“Prosecutors told KREM 2 News on Wednesday that they plan to get tough on Limpert with his latest trial.”
“Larry Haskell, the Spokane County prosecutor, said Limpert’s history of crimes could final[ly] be catching up to him.”
70th time’s the charm, right?
“”I think every day what I could’ve done to prevent myself from getting into trouble,” Limpert told a judge.”
Not get caught; clearly this man needs to work on his skills at not getting caught.
It is possible that Limpert actually has some desire to not get into trouble, but simply lacks any ability to control his actions and act in a non-criminal manner. It is also possible that Limpert just doesn’t want to go to jail for his criminal activities. Either way, nothing’s going to change.
They say that about 1 in 200 people alive today is descended from Genghis Khan (or one of his brothers, if he had any.) Obviously most of the Great Khan’s descendants are in Asia; what about the rest of the world?
“Tracking [Y chromosome] mutations allows scientists to create a family tree of fathers and sons going back through time. … Two-thirds of modern European men are found on just three branches (called I1, R1a and R1b). Our results show that these branches each trace their paternal ancestry to a surprisingly recent individual (shown as red dots in Figure 1). By counting the number of mutations that have accumulated within each branch over the generations, we estimate that these three men lived at different times between 3,500 and 7,300 years ago.”
Female genetics–mitochondrial DNA–show no such feature. “… when looking at this maternal tree, there is no similar explosion. This indicates that whatever factors were responsible for this pattern were specific to men.”
This seems reasonably strong evidence that we aren’t just looking at something that could be explained away as founder/bottleneck effect, because I would expect such an effect to act equally on males and females. However, I don’t know if anyone has adequately addressed the question of patrilocality.
On a potentially related note, another study came up with this graph of Y chromosome diversity over time
Now if you ask me, these look like they’re describing the same phenomenon, but the dates are supposedly different.
A couple of thoughts:
1. I really really wish they’d made the Y Chromosome graph bigger and spread it out more so I can actually see what’s going on. According to the article summarizing the paper, the Siberian population did not suffer a decrease in Y chromosome diversity at this time, but I can’t tell it from looking at the graph.
2. Wow, look at the African Y chromosome diversity drop and then never fully recover. The Near East Y-diversity (the orange part) shoots up much higher than it was initially after the drop, as does the European. If the suspicion that farming was the cause of the drop is correct, then it looks like African Y chromosomes never quite recovered–consistent with the theory that African horticulture has traditionally been easy enough for women to do, leading to polygyny, leading to a few males dominating most of the women and the other males being excluded, etc. See, eg, West African Marriage and Child-Rearing Norms vs. African American Norms. (I’ve got another post on the subject, but it’s not going up for a few more weeks.)
3. What’s been happening to mtDNA diversity in the past few thousand years?
So was it agriculture? Or were did agriculture just make people sitting ducks for horse-born invaders? Or perhaps both?
“3 in 4 former prisoners in 30 states arrested within 5 years of release” (from the Bureau of Justice Statistics press release, April 22, 2014.)Inspired by my recent musings, I thought I would refresh my memory on recidivism stats–I have a vague memory that murderers tend not to recidivate, (murderers tend to stay in prison for a very long time) and that car jackers do, but it’s a bad idea to make claims based on vague memories of old data.
So here’s what the press release has to say:
“An estimated two-thirds (68 percent) of 405,000 prisoners released in 30 states in 2005 were arrested for a new crime within three years of release from prison, and three-quarters (77 percent) were arrested within five years…
More than a third (37 percent) of prisoners who were arrested within five years of release were arrested within the first six months after release, with more than half (57 percent) arrested by the end of the first year.”
We could probably save some time and effort if we could effectively identify those third before releasing them. HOWEVER, I don’t know what percent of these people are being re-arrested on parole violations that the rest of us might not really consider “crimes”, like missing a meeting with one’s parole officer or forgetting to register one’s address.
“Recidivism rates varied with the attributes of the inmate. Prisoners released after serving time for a property offense were the most likely to recidivate. Within five years of release, 82 percent of property offenders were arrested for a new crime, compared to 77 percent of drug offenders, 74 percent of public order offenders and 71 percent of violent offenders.”
I’m guessing violent offenders spent longer in prison, and thus were older when released.
“Recidivism was highest among males, blacks and young adults. By the end of the fifth year after release, more than three-quarters (78 percent) of males and two-thirds (68 percent) of females were arrested, a 10 percentage point difference that remained relatively stable during the entire 5-year follow-up period.
Five years after release from prison, black offenders had the highest recidivism rate (81 percent), compared to Hispanic (75 percent) and white (73 percent) offenders.”
So, while while the chances of being a criminal vary widely between groups, criminals from all the groups recidivate at fairly similar rates. This suggests that we are probably actually arresting the subset of people who are criminals most of the time.
“Within five years of release, 61 percent of released inmates with four or fewer arrests in their prior criminal history were arrested, compared to 86 percent of those who had 10 or more prior arrests.”
Maybe guys with 10 prior arrests shouldn’t be released until they’re well over 40?
Some finer grain on recidivism by specific crime, after five years (note: this does not tell us the new offense,) from the PDF:
Looks like my vague memories were correct. Murderers are the least likely to recidivate, probably due to the personal nature of many murders (you’ve got to really hate that guy,) and murderers being older when released, but they are still folks who aren’t great at solving inter-personal problems or running their lives. Rapist probably figure out non-illegal ways to have sex, or else get old enough to be less interested in it. Drunks probably learn to call a cab when drunk.
Relatively speaking, of course. A 50 or 60% recidivism rate still isn’t something that inspires great confidence. To be clear, again, this is not data on how many released murderers commit another murder or how many released rapists commit another rape–this is arrest for any crime. A further breakdown of re-arrest by new crime vs. old crime would be interesting.Carjacking, by contrast, looks like the Xtreme sports of crime–people attracted to this form of violent thrill-seeking seem unlikely to change their spots or find more legal alternatives.
From the abstract: The role of parenting in the development of criminal behavior has been the source of a vast amount of research, with the majority of studies detecting statistically significant associations between dimensions of parenting and measures of criminal involvement. An emerging group of scholars, however, has drawn attention to the methodological limitations-mainly genetic confounding-of the parental socialization literature. The current study addressed this limitation by analyzing a sample of adoptees to assess the association between 8 parenting measures and 4 criminal justice outcome measures. The results revealed very little evidence of parental socialization effects on criminal behavior before controlling for genetic confounding and no evidence of parental socialization effects on criminal involvement after controlling for genetic confounding.
In other words, looks like my basic thesis is holding up. Overall, I suspect it is far easier to fuck up a kid so they don’t meet their full potential (say, by abusing/neglecting) than to get rid of the effects of negative traits. It’s probably best to try to work with people’s inclinations by finding them life-paths that work for them, rather than trying to mold them into something they aren’t.
There’s an exciting new study on Bronze Age genetics that you’ve probably already heard about but I’m gonna post about anyway because stuff like this is kind of like our core competency around here.
Summary: Scientist people sequenced genomes (did fancy lab things with genetics) on 101 dead Europeans/Asians from a few thousand years ago, to try to figure out who they were and where they came from.
One of the big anthro/archeology debates over the past 70 years or so has been whether the different layers of cultural artifacts (eg, pots) represent things being traded while people stay put, or people invading and bringing their new stuff with them.
To put it in a modern context, if you saw a picture of people from Papua New Guinea taken in 1900, wearing traditional tribal clothes, and then saw a picture taken a few decades later of people from Papua New Guinea wearing Levi’s and T-shirts, you might wonder if the people of PNG had gotten some new clothes, or if some people wearing Levi’s had gone to PNG.
The archaeological assumption pre-1940 or so was generally that different layers of cultural artifacts represented actually different groups of people, who had probably invaded and slaughtered the previous group of people. For a variety of reasons that you can probably figure out on your own, this view fell into disrepute around the mid 1940s, and so was replaced with the peaceful assumption that new cultural artifacts probably spread primarily through trade, not warfare. This is expressed through the phrase, “Pots, not people,” meaning that the pots were moving around, not the people.
So now we can sequence ancient genomes and shit, so we can actually take a look at the people in ancient burials and try to figure out if people in Layer of Pots A are related to people in Layer of Pots B, or if they are a totally different group of people. This is like squinting at the photographs of Papua New Guineans and trying to figure out if the people wearing the clothes look like they come from the same group, but with lab tools and science.
From an archaeology/anthropology perspective, this is big stuff people have been debating about for over a century.
Conclusions: The Yamnaya are the Indo-Europeans (or proto-Indo-Europeans.) They started out around the Ukraine, then about 4,000 years ago, they spread out (cause they had horses and wagons and chariots and such with wheels,) toward the west and east. In Europe they became the Corded Ware Culture. The Corded Ware may have headed toward the Urals and became some of the ancestors of the Indo-Iranians, but that’s still fuzzy.
The Yamnaya had high (relatively) rates of lactose tolerance, so they probably helped spread that gene/the gene helped spread them. Blond hair and blue eyes are not Yamnaya traits–those came from elsewhere. They probably had pale skins, but so did most of the people already in Europe, so they didn’t change that.
I had already figured the Yamnaya were the PIEs (along with a bunch of other people paying even vague attention to the field,) but apparently my rough mental estimate of the time frame was off. 4,000 years ago is not that long–we have quite abundant records of life 2,000 years ago, so imagine what sorts of records or rumors those Greeks and Romans had about life 2,000 years before themselves.
There is much that we once naively took as fact, then skeptically decided was myth, then decided was fact again, like the existence of Troy. (Of course, there is also much that has turned out to be actually false. Like Herodotus’s dog-sized ants.) Perhaps some more of what seems mere myth in the Greek and Roman accounts will turn out to have some basis in history.
On the eastern end of the geographic range they surveyed, the steppe-folks out there were later replaced with a more Asian population that looks more closely related to the Native Americans (possibly descended from a population ancestral to both them and the Native Americans.)
I don’t know yet just how violent the invasion was–the existing European population was not wiped out, a la the Dorset. The groups mixed; modern Europeans (and many Asians) are a mixture of many population waves. But we do know now that these were people, not just their pots.
It seems like people are always trying to use hunter gatherers to further some wacky theory or other. The Paleo Diet isn’t too bad; it is at least a reasonably accurate representation of what hunter-gatherers actually eat, though your chances of replicating hunter-gather food at home are slim–which is why we end up with things like “Paleo Bread.” But then you have the far less accurate theories, often pushed by people who really ought to know better. Like the theory that hunter gatherers had no wars, or that they were all gender egalitarians. Or that there was once a global civilization of feminist goddess-worshipers who were wiped out by evil agriculturalists.
But let’s backtrack a minute. Where do these wacky theories come from?
The short answer is that they come from Marxists. You may laugh or roll your eyes, but I was actually assigned Das Kapital twice in college–once in my major, political science, and once in my minor, anthropology. I was also assigned explicitly Marxist papers in my Feminism class. This was a reputable university where many of my professors were identifiably conservative, not an obvious liberal bastion like Berkley or Reed.
Marx is deep in academia.
You do not have to be explicitly citing Marx or realize that you are using theories of the world derived from Marx to be using one of Marx’s theories, anymore than you have to have studied the Chicago School of Economics or the Austrian School to pick up one of their theories and start using it. But most academics of the past 100 years or so have known the intellectual provenance of their ideas, because like me, they were assigned it in class and no one in academia is shy about explicitly citing Marx.
To be honest, I don’t hate Marx’s theories. I enjoy Bakunin better than Marx, but I understand Marx’s attempt at making a science out of economic history. Not a terribly rigorous science, unfortunately.
This isn’t the time or place for a full explanation of where exactly Marx went wrong–there are far better authors than me who have spilled plenty of ink on the subject if you want to take a look. But suffice to say, real-life experience has not been terribly kind to Marx’s theories. Nonetheless, they still undergird a great deal of academic thinking and were formative in the educations of many, many anthropologists.
And the basic thought process went like this:
Jesus Effin’ Christ, WWII was the most awful, worst thing ever. Nazis are horrifying, racist scum. We need different theories.
Marxism explains human behavior through entirely environmental means, namely the means of production (ie, whether you live in a hunter-gatherer, agricultural, industrial, etc., kind of society.)
Marxism says that humans have wars because capitalists make them–that is, war is a side effect of capitalist society.
Therefore, in the pre-capitalist society, people didn’t have wars.
And then academics went and wrote a lot of things about how they now realized that pre-state people didn’t have wars or violence or were ever mean to each other.
Alas, many a beautiful theory has been destroyed by an ugly fact, and the ugly fact in this case is that pre-state people killed each other all the damn time. Take the Dorset, completely wiped out by the Thule (Inuit) about 700 years ago:
Science 29 August 2014: Vol. 345 no. 6200 DOI: 10.1126/science.125583, Maanasa Raghavan et al.
Those blue bars represent Dorset DNA found in ancient gravesites around the arctic. The red guys represent Thule (Inuit) DNA. The Dorset are gone; their DNA did not make it into the Thule.
Anthropologists and archaeologists have spent the last 70 years or so arguing that if you find one kind of pots in one layer of your excavation, and radically different pots in the next layer, all it means is that people traded for some different pots. In the case of the Dorset, it means the Thule killed them all, a good 200 years before Columbus even set foot anywhere near Cuba.
Speaking of Columbus, he wrote of the Indians he met in the Bahamas, “Many of the men I have seen have scars on their bodies, and when I made signs to them to find out how this happened, they indicated that people from other nearby islands come to San Salvador to capture them; they defend themselves the best they can. I believe that people from the mainland come here to take them as slaves.”
“[The Bushman’s] courage is remarkable, and Fritsch was told by residents who were well qualified to speak that supported by a dozen Bushmen they would not be afraid of a hundred Kaffirs. The terror inspired by the Bushmen has indeed had an effect in the deforestation of parts of Cape Colony, for the colonists, to guard against stealthy attacks, cut down all the bush far round their holdings.
…
Marriage is a matter merely of offer and acceptance ratified by a feast. Among some tribes the youth must prove himself an expert hunter. Nothing is known of the laws of inheritance. … As among other African tribes the social position of the women is low. They are beasts of burden, carrying the children and the family property on the journeys, and doing all the work at the halting-place. It is their duty also to keep the encampment supplied with water, no matter how far it has to be carried.”
Yes, clearly they are bastions of peaceful gender egalitarianism!
“A recent study… gave some astonishing cross-cultural figures. The homicide rate in modern Britain is roughly 0.5/100,000; in the USA it is about 20 times as high, at about 10.5. The highest death rate recorded in a nation, as opposed to a tribe, is 34 / 100,000, in Colombia. Though it is difficult to calculate exact correspondences for much smaller populations, about whom much less is known, it is still clear that Stone Age tribes make up in enthusiasm what they lack in the technology of murder. Even the !Kung bushmen, popularised as “The Harmless People”, had a had a homicide rate of 41.9 on this scale; the Yanomamo come in at 165. The record appears to be held by the Hewa people of New Guinea, with a score of 778. … the Murngin hunter-gatherer aborigines of Northern Australia come in with a score of 330.” –from The Darwin Wars, by Andrew Brown, (you can find excerpts on Brown’s promotional website for the book.)
Of the Yanomamo, Brown notes, ” There are fashions in noble savages as in other things, and the Yanomamo, a warlike and intermittently cannibal tribe living on the borders of Brazil and Venezuela, are one of the most heavily studied and nastiest in their habits of all the unspoiled people in the Seventies and Eighties. …
The tribes are quite exceptionally violent and sexist. The Yanomamo term for marriage translates literally as “dragging something away”; their term for divorce is “throwing something away.” [My emphasis, not Brown’s.] Villages war with villages; villagers with each other. They use poisoned arrows, spears and wooden clubs. When nothing much seems to be happening in the world outside, villagers will fight with long poles: two men will stand facing each other, and exchange insults. Then they will take turns to punch each other in the chest as hard as possible. Finally they take up long flexible poles, and — once more taking turns — smash each other around the head with them until the loser is felled, unconscious and bleeding all over his head. To quote one lurid description: “A man with a special grudge against another challenges his adversary to hit him on the head with an eight foot long pole shaped like a pool cue. The challenger sticks his own pole in the ground, leans on it, and bows his head. His adversary holds his pole by the thin end, whipping the heavy end down on the proffered pate with bone-crushing force. Having sustained one blow, the recipient is entitled to an immediate opportunity to wallop his opponent in the same manner.”
And if we go back to the data cited at the top of the post, Steven Pinker estimates, in The Better Angels of our Nature, that about 15% of people died of violence–murder or warfare–in pre-state societies.
This is about the same % as the Russians lost in WWII, if we go with the high estimate of Soviet casualties–about half that if we take the low estimate. Of course, hunter gatherers live to be about 45, while WWII was compressed into 6 years, so the death rate was rather faster during WWII, but if you did manage to survive, you lived the rest of your 60 or 70 years in relative peace.
In short, Marx obviously missed some major factors that lead people to kill each other, and anthropologists, not necessarily trained in things like analyzing crime statistics, ran with the idea, producing books with titles like “The Harmless People” about the Bushmen.
Unfortunately, wanting something to be true is not the same as it being true.
So what’s the real story?
Put yourself in the bare feet of a hunter-gatherer, unfettered by the rules and oppressions of the modern state. You meet a random stranger. Kill him, and you can take his pile of nuts, his gourd of water, and his wife. Don’t kill him, and he can kill you and take your nuts, water, and wife. There are no police in your society, so who’s going to stop you?
Throughout pre-history, the men who killed their neighbors and took their wives became your ancestors, and the men who didn’t got killed.
“Citing recent DNA research, Dr. Baumeister explained that today’s human population is descended from twice as many women as men. Maybe 80 percent of women reproduced, whereas only 40 percent of men did.”–Is There Anything Good About Men?
This is, literally, evolution in action. This is survival of the fittest, the struggle to reproduce and pass your genes on to the next generation.
Interestingly, Genghis Khan’s empire, after the massacres, was supposedly very safe–it was said that a woman carrying a bag of gold could walk unmolested, alone, from one end of the empire to the other. Probably an exaggeration, but in general, you did not mess with Genghis Khan’s money-making trade routes unless you wanted to be dead.
As has been said many times, the State demands a monopoly on the use of violence, punishing–often killing–those who would take the ancestral route to paternity. This is a novel evolutionary pressure–the collective pressure of the state against the violent.
Thus violent crime rates have plummeted in state-societies over the past 5,000 years or so:
Peter Frost lays out this argument excellently in his post, “The Genetic Pacification of Europe“–basically the idea that European governments have been executing their violent criminals (or otherwise letting them die in jail) for centuries, resulting in a drastic reduction in the prevalence of genes coding for violence in areas with long histories of strong, organized state rule.
According to Wikipedia, monoamine oxidase A, also known as the “warrior gene”, is associated with several types of antisocial behavior. “…individuals with the low activity MAO-A gene, when faced with social exclusion or ostracism showed higher levels of aggression than individuals with the high activity MAO-A gene. Low activity MAO-A could significantly predict aggressive behaviour in a high provocation situation, but was less associated with aggression in a low provocation situation. Individuals with the low activity variant of the MAO-A gene were just as likely as participants with the high activity variant to retaliate when the loss was small. However, they were more likely to retaliate and with greater force when the loss was large.”
Also, “The frequency distribution of variants of the MAO-A gene differs between ethnic groups. 59% of Black men, 54% of Chinese men, 56% of Maori men, and 34% of Caucasian men carry the 3R allele. 5.5% of Black men, 0.1% of Caucasian men, and 0.00067% of Asian men carry the 2R allele.”
Now, as HBD Chick has pointed out, we aren’t just looking at states at agents of pacification, we’re looking especially at a specific sub-set of states. Like those inside the Hajnal Line, where the Catholic church forbade cousin marriage (one of the preferred forms of marriage throughout the rest of the world, actually,) a thousand and a half or so years ago, leading to the breakup of the barbarian tribal/clan systems and the genetic prerequisites for living in modern states (I assume something functionally kinda similar has happened in China and Japan, since they also have low crime rates, but that requires more research.)
“According to a survey of 93 nonindustrial cultures, men were expected to dominate their wives in 67% of them, the sexes were expected to be about equal in 30%, and women were expected to dominate their husbands in 3% (Whyte, 1978). Sex roles differ to varying degrees even among hunter-gatherers, who correspond to the earliest stage of cultural evolution. In the tropics, women provide more food through gathering than men do through hunting. The reverse is true beyond the tropics, where women have few opportunities to gather food in winter (Kelly, 1995, pp. 128-132; Martin, 1974, pp. 16-18).”
Also:
“English psychologist John T. Manning has pioneered the use of this digit ratio as a way to measure how prenatal male and female hormones influence various behavioral traits. In a recent study, he looked at how prenatal hormones might influence gender equality in different populations. After measuring the digit ratios of participants from 29 countries, his research team averaged the score for each country and compared it with indices of gender equality: women’s share of parliamentary seats; women’s participation in the labor force, women’s education attainment level; maternal mortality rates; and juvenile pregnancy rates. To ensure comparability, all of the participants were of European descent.
… the more similar the two sexes were in 2D:4D, the more equal were the two sexes in parliamentary and labor force participation. The other variables were not as strongly correlated. (Manning et al., 2014)
In general, women from Northwest Europe have more masculine digit ratios, whereas women from farther east and south have more feminine digit ratios. This geographical trend is more pronounced for the right hand than for the left hand. Since the right-hand digit ratio is associated with social dominance, Northwest Europeans may be less sexually differentiated for that particular trait, as opposed to being less sexually differentiated in general.
Presumably, this isn’t a new tendency. Women must have been more socially dominant among Northwest Europeans even before the late 19th century and the earliest movements for women’s suffrage. So how far back does the tendency go? To medieval times? To pre-Christian times? It seems to go back at least to medieval times and, as such, forms part of the Western European Marriage Pattern:
‘The status of women differed immensely by region. In western Europe, later marriage and higher rates of definitive celibacy (the so-called “European marriage pattern”) helped to constrain patriarchy at its most extreme level.
[…] In eastern Europe however, the tradition of early and universal marriage (usually of a bride aged 12-15 years, with menarche occurring on average at 14) as well as traditional Slavic patrilocal customs led to a greatly inferior status of women at all levels of society. (Women in the Middle Ages, 2014)’ ”
If you’re looking for a peaceful, gender-egalitarian society, don’t look to prehistory, hunter gatherers, or non-state societies. Look at your own country. It’s probably pretty good.
Impulsive people die younger than non-impulsive people, so much so that how your teacher rated you as a student back when you were a kid is actually a decent predictor of your later mortality.
. The first two probable reasons for this are obvious:
1. They do risky things like drive too fast, hold up conbinis, or take drugs, all of which can actually kill you.
2. They engage in behaviors with potentially negative long-term consequences, like eating too many donuts or failing out of school and having to do a crappy job with bad safety precautions.
But the third reason is less obvious, unless you’re Jayman:
3. There is no point to planning for the future if you’re going to die young anyway.
Some people come from long-lived people. They have genes that will help keep them alive for a very long time. Some people don’t. These people live fast. They walk earlier, they mature earlier, they get pregnant earlier, and they die earlier. Everything they do is on a shorter timeframe than the long-lived people. To them, they aren’t impulsive–everyone else is just agonizingly slow.
Why save for retirement if you’re not going to live that long?
Impulsive people are like normal people, just sped up.
My grandfather was a badass kind of guy, so of course his dogs were awesome, too.
He lived in a part of the country where coyotes were still a problem for livestock producers (it’s always a bummer when your favorite chicken gets eaten,) so he got this German Shepherd.
The German Shepherd proceeded to kill all the male coyotes in the area.
The next spring, we kept spotting half-German Shepherd, half-coyote pups.
Unlike mules, coydogs are fertile, and can continue making more generations of coydogs–or whatever they happen to mate with. In fact, it appears that most species of the Canis genus–various wolves, domestic dogs, dingoes, coyotes, and some jackals–can interbreed. Foxes and other less-closely related members of the family Canidae, however, cannot breed with canids–they have different numbers of chromosomes, which makes the genetics not really work.
(This is what is up with mule, btw. Horses and donkeys have different numbers of chromosomes.)
The history of different canid species actually gets kinda complicated when you look at the inter-species mixing. According to the Wikipedia:
“…melanistic coyotes have been shown to have inherited their black pelts from dogs likely brought to North America through the Bering Land Bridge 12,000 to 14,000 years ago by the ancestors of the America’s indigenous people.”
” Northern Canada’s Aboriginal populations were mating coyotes and wolves to their sled dogs in order to produce more resilient animals as late as the early 20th century.”
(Well that explains the wolf admixture in National Geographic’s article on dog genetics! I’ve been wondering about that.)
“Some 15% of 10,000 coyotes taken annually in Illinois for their fur during the early 1980s may have been coydogs based on cranial measurements… Of 379 wild canid skulls taken in Ohio from 1982 to 1988, 10 (2.6%) were found to be coydogs.”
“Coyotes have hybridized with wolves to varying degrees, particularly in the Eastern United States and Canada. The so-called “eastern coyote” of northeastern North America has been confirmed to be of mixed wolf-coyote parentage, and probably originated in the aftermath of the extermination of wolves in the northeast, thus allowing coyotes to colonize former wolf ranges and mix with remnant wolf populations.”
” In 2011, an analysis of 48,000 SNP chips in the genomes of various wolf and coyote populations revealed that the eastern wolf …and the red wolf… both previously labeled as species distinct from the gray wolf, are in fact products of varying degrees of wolf-coyote hybridization. The wolf-coyote admixture resulting in the development of the eastern wolf may have occurred on the order of 600–900 years ago between gray wolves and a now extinct pre-Columbian coyote population. The eastern wolf has since backcrossed extensively with parent gray wolf populations. The red wolf may have originated later, approximately 287–430 years ago, when much of the southeastern U.S. was being converted to agriculture and predators were targeted for extermination. During this period, declining local wolf populations would have been forced to mate with coyotes, with the resulting hybrids backcrossing to coyotes as the wolves disappeared, to the extent that ~75–80% of the modern red wolf’s genome is of coyote derivation.“
“…since 1975, Russian scientists have bred quarter jackal hybrids, initially from jackals and Lapponian Herder reindeer herding dogs, called Sulimov dogs in order to take advantage of the jackal’s superior olfactory abilities combined with the Lapponian Herder’s resistance to cold. They are owned by Aeroflot – Russian Airlines and trained as sniffer dogs for use in airports. According to the breed’s creator, first-generation hybrid pups could only be produced by male dogs and female jackals, as male jackals refused to mate with female dogs.”
I suspect a lot of genetic traits (being that many involve the complex interaction of many different genes) are such that having a little bit of the trait is advantageous, but having too much (or conversely, too little) is negative.
A few obvious examples:
Aggression: too much, and you go to jail. Historically, prison conditions were awful enough in the West that this likely exerted an upper bound on the population’s criminality by eliminating violent people from the gene pool.
But too little, and you get taken advantage of. You can’t compete in job interviews, get promoted, make friends, or ask people out on dates. Aggressive people take your stuff, and you can’t protect against them.
From getting jobs to getting mates to not being mugged, a little bit of aggression is clearly a good thing.
Intelligence: High IQ is tremendously mal-adaptive in modern society. (This may always have been true.) The upper end of the IQ curve basically does not have children. (On both micro and macro levels.) I’m not prepared to say whether this is a bug or a feature.
But, low IQ appears to also maladaptive. This was certainly true historically in the West, where extremely high death rates and intense resource competition left the dumber members of society with few surviving offspring. Dumb people just have trouble accomplishing the things necessary for raising lots of children.
Somewhat above average IQ appears to be the most adaptive, at least in the present and possibly historically.
Height: Really tall men have health problems and die young. Really short men are considered undateable and so don’t have children. So the pressure is to be tall, but not too tall.
(Speculatively) Depression: Too much depression, and you commit suicide. Not enough, and you’re a happy-go-lucky person who drops out of school and punches people. Just enough, and you work hard, stay true to your spouse, don’t get into fights, and manage to do all of the boring stuff required by Western society. (Note: this could have changed in the past hundred years.)
Sickle Cell Anemia: I don’t think I need to explain this one.
(Also speculative) Tay Sach’s: Tay Sach’s is a horrible neurological disease that shows up in populations with evidence of very high recent pressure to increase IQ, such as Ashkenazim (one of the worlds’ highest IQ groups) and Quebecois. There is therefore speculation that in its heterozygous form, Tay Sach’s may enhance neural development, instead of killing you hideously.
Depression and suicide have non-immediately obvious distributions–countries with things like low crime rates, social equality, and plenty of food tend to have really high rates, while poor, violent countries seem to be quite happy.
Latin American countries, for example, score quite high on happiness surveys, despite being some of the world’s most violent places.
By contrast, the Japanese and Scandinavians have some of the world’s highest rates of suicide.
When something doesn’t make sense, try inverting it: Why might it be useful to be depressed?
I posit that in societies where delaying gratification, working hard, and tolerating high densities of people without getting into fights are prerequisites to reproducing (which has historically been true of China, Japan, and the West,) mild to sub-clinical levels of depression helped people succeed.
(Remember, the phenomenon of most orphans and illegitimate children surviving infancy is only about a hundred years old. Historically, these children almost all died.)
This is where I draw an analogy to Sickle Cell Anemia. With SCA, No SC chromosome = you get malaria. One SC chromosome = you’re not as healthy, but you’re protected against malaria. Two SC chromosomes = you die.
With depression, No Depression => Fun, risky behaviors => you never get a farm and die without any surviving offspring. One Depression trait => you’re not quite sure about this “fun” business => work hard, get a farm, and have children. Two Depression traits => Suicide.
(Obviously depression need not be caused by a mere one or two genes for the idea to hold.)
Seems like the question for Utilitarians becomes, “Is there a way to make people productive, non-violent, and happy, all at the same time?”
