Anthropology Friday: Pygmies and Papuans pt 2

Papuan man accompanied by two Tapiro Pygmies, from Wollaston’s Pygmies and Papuans

Welcome back to Anthropology Friday. Today we are reading A. F. R. Wollaston’s Pygmies and Papuans, published in 1912. Wollaston’s primary purpose in traveling to Papua New Guinea was to study the birds (as was Jared Diamond’s,) but he decided to also write about the people he met.

One of the parts of this book I found most amusing was Wollaston’s struggle to learn the language of the local Mimika Papuans:

“It has been stated in the previous chapters that the natives told us this or that, and that we asked them for information about one thing or another. From this the reader must not conclude that we acquired a very complete knowledge of the native language, for that, unfortunately, was not the case, and even at the end of the fifteen months that we spent in their country we were not able to converse with them. Lieutenant Cramer and I compiled a vocabulary of nearly three hundred words, and we talked a good deal with the people, but we never reached the position of being able to exchange ideas on any single subject. …

“It is unfortunate that there is no common language along the S. coast, nor even a language with words common to all the dialects in use. We were visited on one occasion by the Dutch Assistant Resident from Fak-fak; the native interpreter who came with him, and who knew all the native dialects of the Fak-fak district, could not understand one word of the Mimika language. On another occasion some natives from Mimika were taken down by steamer to Merauke, the Government post in S.W. New Guinea, not far from the boundary of British Papua, and there they found the language of the natives quite unintelligible to them.

“So we found ourselves confronted with the task of learning a language with neither grammar, dictionary nor interpreter. This may not seem to be an insuperable difficulty, nor is it perhaps where Europeans and educated people are concerned, but with Papuans it is a very different problem. The first thing to do—and very few of them would even grasp the idea—is to make them understand that you wish to learn their words. You may point at an object and look intelligent and expectant, but they are slow to take your meaning, and they soon tire of giving information. The facial expression, which amongst us conveys even to a deaf man an interrogation, means nothing to them, nor has the sideways shake of the head a negative meaning to Papuans.”


“In trying to learn a new language of this kind most people (I imagine) would begin, as we did, with the numerals. But our researches in this direction did not take us very far, for we made the interesting discovery that they have words for one and two only; ínakwa (one), jamaní (two). This is not to say that they cannot reckon beyond two, for they can, by using the fingers and thumbs, and beginning always with the thumb of the right hand, reckon with tolerable accuracy up to ten. For numbers above ten they use the toes, never, so far as we observed, two or three toes, but always all the toes together to indicate a large but uncertain number. Sometimes they opened and closed the fingers of both hands two or three times and uttered the word takirí, which appeared to mean “many.” They did not, as some people do, use the word which means “hand” to indicate five or a quantity of about that number.”

EvX: For more on societies with very few words for numbers, see Caleb Everet’s Numbers and the Making of Us. It is interesting to note what a wide variety of numerical systems exist in the world–not only systems that employ unfamiliar bases like five, 20, 60, or twelve, or linguistic systems with a triplet form (just as we have a plural), but also systems in which numbers are highly constrained, like that of the Mimiko, who have only the numerals for one and two (plus use of their hands and toes,) or more extremely, like the Piraha, who have no numbers at all.


“With patience we learnt a great number of substantives, the names of animals, the parts of the body, the various possessions of the natives and so forth, and with more difficulty we learnt some of the active verbs. But when we came to abstract ideas, our researches ceased abruptly for lack of the question words, who, how, where, when, etc.; these we were never able to learn, and it is impossible to act them.

“Thus we were never able to find out what they thought of various things; we could point to the moon and be told its name, but we were never able to say, “What is the moon?” We learnt the names of lightning and thunder, but we never knew who they thought produced them. We could not find out where their stone axes came from, nor how old they were, nor who made them; and a hundred other questions, which we should have liked to put, remained unanswered.”

An Amusing Mistake

“Even the apparently simple matter of enquiring the names of places is not so easy as one would think. When the first party went up the Mimika to Parimau they pointed to the huts and asked what the village was called; the answer given was “Tupué,” meaning I believe, the name of the family who lived in the huts pointed at. For several months we called the place Tupué, and the name appeared in various disguises in the English newspapers.

When I was at Parimau in July, it occurred to me to doubt the name of Tupué, which we never heard the natives use, so I questioned a man elaborately. Pointing in the direction of Wakatimi, I said in his language: “Many houses, Wakatimi,” and he nodded assent; then pointing in the direction of another village that we had visited I said: “Many houses, Imah,” to which he agreed; then I said. “Many houses,” and pointed towards Parimau. This performance was repeated three times before he understood my intention and supplied the word “Parimau,” and then he shouted the whole story across the river to the people in the village who received it with shouts of laughter, and well they might. It was as if a foreigner, who had been living for six months in a place which he was accustomed to call Smith, enquired again one day what its name was and found that it was London. …

Physical Features

“The skin of the Mimika native is a very dark brown, almost rusty black, but a dark colour without any of the gloss seen in the skin of the African negro. Not infrequently we saw men of a lighter, nearly yellow, colour, and in the Wakatimi district there were three pure albinos, a man, a woman and a child. The man and woman were covered with blotches of a pinkish pigment and were peculiarly disagreeable to look at, the child, a sucking infant, and the offspring of black parents, was as white as any European baby, and was called, out of compliment to us, “Tuana.”

“The hair is black and thick and frizzly; it never, or seldom grows long, so you do not see the ornamental coiffures characteristic of the natives of some other parts of the island … The hair of young children is often quite fair, but it becomes dark as they grow up; some of the adults have the custom, common in other places, of dyeing the hair yellow with lime. …

“Tattooing, in the proper sense of the term, is unknown to the Mimika Papuans, but a great number of them practise cicatrisation or scarring. The usual places for these markings are the buttocks and the outer side of the upper (usually the left) arm. …

“The average height of men measured at Wakatimi and Parimau is 5 feet 6 inches. … Such a height is small compared with that of many races, but the first impression you get of the Papuans is that they are tall, for they hold themselves well, and all naked people look taller than those who go clothed. Their legs are thin and rather meagre, due in a great measure to the large proportion of their lives that is spent in canoes, but they walk with a good swinging gait and cover the ground easily.”

The river at high tide


“Beyond question, the happiest time in the lives of the Papuans is their childhood, when they are free to play from morning to night and need not take part in the ceaseless search for food, which occupies so much of the time of their elders. As infants they are carried on the backs of their mothers and very often of their fathers, secured by a wide strap of bark cloth, the ends of which are tied across the carrier’s chest. It is very seldom that you hear them cry and they appear to give very little trouble; their mothers are very careful of the cleanliness of the infants. Very early in life they begin to walk and almost as soon they learn to swim. In fine weather they often spend the greater part of the day in the river and it is a very pretty sight to see a crowd of little Papuans playing together in the water. … They very soon become powerful swimmers, and I remember one day seeing a small boy, who cannot have been more than eight years old, swim across a river in tremendous flood, while the party of men who were with him had to seek a place where they could safely swim across half a mile lower down.


“There are a number of games too that they play on dry land: they play the universal game of lying in wait for your enemy and suddenly pouncing out on him; they have great battles in which they are armed with miniature bows and arrows, and reed stems take the place of spears, and shrill yells make up for the lack of bloodshed. …


“Generally speaking, one would say that the society of the Mimika Papuans is a group of small families. It cannot by any means be described as a socialistic community; with one exception there is no sign of community of property, but it is rather a case of every man for himself, or (more accurately) of every family for itself. A canoe belongs to the family of the man who made it; the coconut trees, which grow here and there along the lower Mimika, do not belong to the community but to individuals, presumably the men or some of the men who planted them. … The exception mentioned is seen when game is brought in by the hunters; the meat, as I observed on several occasions, is distributed to every house in the village. …

“From the description of them which has been given in this and the two preceding chapters it will be seen that the conditions of life of the Papuans are as primitive as those of any people now living in the world. There are very few other places, where you can find a people who neither make nor possess any metal and who have no knowledge of pottery. The only vessels that they have for holding water are scraped-out coconuts and simple pieces of bamboo. Water boiling they had never seen before we came among them. Their implements and weapons are, as I have shown, of the most primitive kind, and their ornaments are of the rudest possible description.

Cultivation of the soil is only practised by the people of one or two villages, and even then it produces but a very small proportion of their food, so it follows that most of their time and energies are devoted to procuring the necessaries of life.


“The struggle for existence is keen enough, the birth-rate is low and the rate of infant mortality is, I believe, very high. Nor do diseases spare them; syphilis is exceedingly prevalent, and was probably introduced by Chinese and Malay traders to the West end of the island, whence it has spread along the coast. Tuberculosis is happily absent, but two natives of Wakatimi were suffering from what appeared to be certainly leprosy. Skin diseases, notably tinea imbricata, are very common; and almost every person appears to suffer occasionally from fever of one sort or another.

“But in spite of all these drawbacks the Papuans of the Mimika are not such a very miserable people. They are strong, those of them that survive the ordeals of infancy and sickness; they have food in plenty to eat, if they choose to exert themselves sufficiently to obtain it; they have their amusements, songs and dances; and the manner of their lives is suited to the conditions of the country in which they live. It is this last consideration which ought ultimately to determine their fate: they live in a wretchedly poor country which is constantly liable to devastating floods, and their habit of wandering from one place to another, where food may be obtained, is the only way of life suitable to the physical and climatic conditions of the country.

The case against “civilizing”

“Any attempt to “civilise” them must inevitably destroy their primitive independence, and if it succeeded in establishing the people in settled communities it would reduce them at many seasons to absolute starvation. We were visited once by the Director of the Sacred Heart Mission at Toeal, which has done admirable work amongst the natives of the Ké Islands and at one or two places in New Guinea itself. When he had seen the people and the nature of the country and had been told something of their habits, he decided that the Mimika was not, at present at all events, a proper field for missionary enterprise. Setting aside all other considerations, one dares to hope that such an interesting people may for a long time be left undisturbed; they do no harm to their neighbours and the effects on them of civilising influences would be at the best uncertain.”

The Negritos of Sundaland, Sahul, and the Philippines

Ati (Negrito) woman from the Philippines

The Negritos are a fascinating group of short-statured, dark-skinned, frizzy-haired peoples from southeast Asia–chiefly the Andaman Islands, Malaysia, Philippines, and Thailand. (Spelling note: “Negritoes” is also an acceptable plural, and some sources use the Spanish Negrillos.)

Because of their appearance, they have long been associated with African peoples, especially the Pygmies. Pygmies are formally defined as any group where adult men are, on average 4’11” or less and is almost always used specifically to refer to African Pygmies; the term pygmoid is sometimes used for groups whose men average 5’1″ or below, including the Negritos. (Some of the Bushmen tribes, Bolivians, Amazonians, the remote Taron, and a variety of others may also be pygmoid, by this definition.)

However, genetic testing has long indicated that they, along with other Melanesians and Australian Aborigines, are more closely related to other east Asian peoples than any African groups. In other words, they’re part of the greater Asian race, albeit a distant branch of it.

But how distant? And are the various Negrito groups closely related to each other, or do there just happen to be a variety of short groups of people in the area, perhaps due to convergent evolution triggered by insular dwarfism?

From Wikimedia

In Discerning the origins of the Negritos, First Sundaland Peoples: deep divergence and archaic admixture, Jinam et al gathered genetic data from Filipino, Malaysian, and Andamanese Negrito populations, and compared them both to each other and other Asian, African, and European groups. (Be sure to download the supplementary materials to get all of the graphs and maps.)

They found that the Negrito groups they studied “are basal to other East and Southeast Asians,” (basal: forming the bottom layer or base. In this case, it means they split off first,) “and that they diverged from West Eurasians at least 38,000 years ago.” (West Eurasians: Caucasians, consisting of Europeans, Middle Easterners, North Africans, and people from India.) “We also found relatively high traces of Denisovan admixture in the Philippine Negritos, but not in the Malaysian and Andamanese groups.” (Denisovans are a group of extinct humans similar to Neanderthals, but we’ve yet to find many of their bones. Just as Neanderthal DNA shows up in non-Sub-Saharan-Africans, so Denisvoan shows up in Melanesians.)

Figure 1 (A) shows PC analysis of Andamanese, Malaysian, and Philippine Negritos, revealing three distinct clusters:

In the upper right-hand corner, the Aeta, Agta, Batak, and Mamanwa are Philippine Negritos. The Manobo are non-Negrito Filipinos.

In the lower right-hand corner are the Jehai, Kintak and Batek are Malaysian Negritos.

And in the upper left, we have the extremely isolated Andamanese Onge and Jarawa Negritos.

(Phil-NN and Mly-NN I believe are Filipino and Malaysian Non-Negritos.)

You can find the same chart, but flipped upside down, with Papuan and Melanesian DNA in the supplemental materials. Of the three groups, they cluster closest to the Philippine Negritos, along the same line with the Malaysians.

By excluding the Andamanese (and Kintak) Negritos, Figure 1 (B) allows a closer look at the structure of the Philippine Negritos.

The Agta, Aeta, and Batak form a horizontal “comet-like pattern,” which likely indicates admixture with non-Negrito Philipine groups like the Manobo. The Mamanawa, who hail from a different part of the Philippines, also show this comet-like patterns, but along a different axis–likely because they intermixed with the different Filipinos who lived in their area. As you can see, there’s a fair amount of overlap–several of the Manobo individuals clustered with the Mamanwa Negritos, and the Batak cluster near several non-Negrito groups (see supplemental chart S4 B)–suggesting high amounts of mixing between these groups.

ADMIXTURE analysis reveals a similar picture. The non-Negrito Filipino groups show up primarily as Orange. The Aeta, Agta, and Batak form a clear genetic cluster with each other and cline with the Orange Filipinos, with the Aeta the least admixed and Batak the most.

The white are on the chart isn’t a data error, but the unique signature of the geographically separated Mananwa, who are highly mixed with the Manobo–and the Manobo, in turn, are mixed with them.

But this alone doesn’t tell us how ancient these populations are, nor if they’re descended from one ancestral pop. For this, the authors constructed several phylogenetic trees, based on all of the data at hand and assuming from 0 – 5 admixture events. The one on the left assumes 5 events, but for clarity only shows three of them. The Denisovan DNA is fascinating and well-documented elsewhere in Melanesian populatons; that Malaysian and Philippine Negritos mixed with their neighbors is also known, supporting the choice of this tree as the most likely to be accurate.

Regardless of which you pick, all of the trees show very similar results, with the biggest difference being whether the Melanesians/Papuans split before or after the Andamanese/Malaysian Negritos.

In case you are unfamiliar with these trees, I’ll run down a quick explanation: This is a human family tree, with each split showing where one group of humans split off from the others and became an isolated group with its own unique genetic patterns. The orange and red lines mark places where formerly isolated groups met and interbred, producing children that are a mix of both. The first split in the tree, going back million of years, is between all Homo sapiens (our species) and the Denisovans, a sister species related to the Neanderthals.

All humans outside of sub-Saharan Africans have some Neanderthal DNA because their ancestors met and interbred with Neanderthals on their way Out of Africa. Melanesians, Papuans, and some Negritos also have some Denisovan DNA, because their ancestors met and made children with members of this obscure human species, but Denisovan DNA is quite rare outside these groups.

Here is a map of Denisovan DNA levels the authors found, with 4% of Papuan DNA hailing from Denisivan ancestors, and Aeta nearly as high. By contrast, the Andamanese Negritos appear to have zero Denisovan. Either the Andamanese split off before the ancestors of the Philippine Negritos and Papuans met the Denisovans, or all Denisovan DNA has been purged from their bloodlines, perhaps because it just wasn’t helpful for surviving on their islands.

Back to the Tree: The second node is where the Biaka, a group of Pygmies from the Congo Rainforest in central Africa. Pygmy lineages are among the most ancient on earth, potentially going back over 200,000 years, well before any Homo sapiens had left Africa.

The next group that splits off from the rest of humanity are the Yoruba, a single ethnic group chosen to stand in for the entirety of the Bantus. Bantus are the group that you most likely think of when you think of black Africans, because over the past three millennia they have expanded greatly and conquered most of sub-Saharan Africa.

Next we have the Out of Africa event and the split between Caucasians (here represented by the French) and the greater Asian clade, which includes Australian Aborigines, Melanesians, Polynesians, Chinese, Japanese, Siberians, Inuit, and Native Americans.

The first groups to split off from the greater Asian clade (aka race) were the Andamanese and Malaysian Negritos, followed by the Papuans/Melanesians Australian Aborigines are closely related to Papuans, as Australia and Papua New Guinea were connected in a single continent (called Sahul) back during the last Ice Age. Most of Indonesia and parts of the Philippines were also connected into a single landmass, called Sunda. Sensibly, people reached Sunda before Sahul, though (Perhaps at that time the Andaman islands, to the northwest of Sumatra, were also connected or at least closer to the mainland.)

Irrespective of the exact order in which Melanesians and individual Negrito groups split off, they all split well before all of the other Asian groups in the area.

This is supported by legends told by the Filipinos themselves:

Legends, such as those involving the Ten Bornean Datus and the Binirayan Festival, tell tales about how, at the beginning of the 12th century when Indonesia and Philippines were under the rule of Indianized native kingdoms, the ancestors of the Bisaya escaped from Borneo from the persecution of Rajah Makatunaw. Led by Datu Puti and Datu Sumakwel and sailing with boats called balangays, they landed near a river called Suaragan, on the southwest coast of Panay, (the place then known as Aninipay), and bartered the land from an Ati [Negrito] headman named Polpolan and his son Marikudo for the price of a necklace and one golden salakot. The hills were left to the Atis while the plains and rivers to the Malays. This meeting is commemorated through the Ati-atihan festival.[4]

The study’s authors estimate that the Negritos split from Europeans (Caucasians) around 30-38,000 years ago, and that the Malaysian and Philippine Negritos split around
13-15,000 years ago. (This all seems a bit tentative, IMO, especially since we have physical evidence of people in the area going back much further than that, and the authors themselves admit in the discussion that their time estimate may be too short.)

The authors also note:

Both our NJ (fig. 3A) and UPGMA (supplementary fig. S10) trees show that after divergence from Europeans, the ancestral Asians subsequently split into Papuans, Negritos and East Asians, implying a one-wave colonization of Asia. … This is in contrast to the study based on whole genome sequences that suggested Australian Aboriginal/Papuan first split from European/East Asians 60 kya, and later Europeans and East Asians diverged 40 kya (Malaspinas et al. 2016). This implies a two-wave migration into Asia…

The matter is still up for debate/more study.

Negrito couple from the Andaman Islands

In conclusion: All of the Negrito groups are likely descended from a common ancestor, (rather than having evolved from separate groups that happened to develop similar body types due to exposure to similar environments,) and were among the very first inhabitants of their regions. Despite their short stature, they are more closely related to other Asian groups (like the Chinese) than to African Pygmies. Significant mixing with their neighbors, however, is quickly obscuring their ancient lineages.

I wonder if all ancient human groups were originally short, and height a recently evolved trait in some groups?

In closing, I’d like to thank Jinam et al for their hard work in writing this article and making it available to the public, their sponsors, and the unique Negrito peoples themselves for surviving so long.

YES Two Out of Africa Events! (Also, Aborigines)

I’ve long suspected (given the archaeological evidence, like 80,000 year old human remains in China,) that there were two Out of Africa (OOA) events–an early one that headed east, toward Australia, and a later one that headed everywhere (including Australia)–and now it looks like this has been genetically confirmed:

Isn’t this a great graphic? My hat’s off to the Estonians. Beautiful work.

Here’s another one they made (sadly small) with less color and more detail on the Eurasian lines. (IIRC, Chinese have more Neanderthal ancestry than Europeans, so technically the schematic ought to be a wee bit more complicated than this, but it’s already complicated enough and this is a solid general overview.)

It might just be the sleep dep + lots of coffee talking, but I am so excited about this.

Some quotes from the NY Times article:

In Israel, for example, researchers found a few distinctively modern human skeletons that are between 120,000 and 90,000 years old. In Saudi Arabia and India, sophisticated tools date back as far as 100,000 years.

Last October, Chinese scientists reported finding teeth belonging to Homo sapiens that are at least 80,000 years old and perhaps as old as 120,000 years. …

Examining their data separately, all three groups came to the same conclusion: People everywhere descend from a single migration of early humans from Africa. The estimates from the studies point to an exodus somewhere between 80,000 and 50,000 years. …

n Papua New Guinea, Dr. Metspalu and his colleagues found, 98 percent of each person’s DNA can be traced to that single migration from Africa. But the other 2 percent seemed to be much older.

Dr. Metspalu concluded that all people in Papua New Guinea carry a trace of DNA from an earlier wave of Africans who left the continent as long as 140,000 years ago, and then vanished.

Obviously, in science, replication and caution are key. Don’t get too excited. These results might turn out to be wrong–sometimes samples get contaminated or data coded incorrectly and we get results that turn out to be completely wrong. And, okay, this isn’t really “huge” in the grand scheme of things–we’re only talking about 2% of Papuans’ ancestors, not, like, 40% of them. But it does explain all of those anomalously old findings.

Now someone needs to explain the Red Deer Cave People:

The Red Deer Cave People were the most recently known prehistoric Hominin population that did not look like modern humans. Fossils dated to between 14,500 and 11,500 years old were found in Red Deer Cave and Longlin Cave in China. Having a mix of archaic and modern features, they are (tentatively) thought to be a separate species of humans that persisted until recent times and became extinct without contributing to the gene pool of modern humans.[1]

On a related note, we have some awesome news about Aborigine DNA/language trees: A genomic history of Australia and Why Australia is home to one of the Largest Language Families in the World. (Well duh it’s because Aborigines spent thousands of years as tiny bands of hunter gatherers, in which each isolated band started developing its own language.) These articles have an oddly inverted structure, (burying the lead, I guess,) so let’s rearrange the abstract for coherency:

We estimate that Aboriginal Australians and Papuans diverged from Eurasians 51–72 kya, following a single out-of-Africa dispersal, and subsequently admixed with archaic populations. … Papuan and Aboriginal Australian ancestors diversified 25–40 thousand years ago (kya), suggesting pre-Holocene population structure in the ancient continent of Sahul (Australia, New Guinea and Tasmania). However, all of the studied Aboriginal Australians descend from a single founding population that differentiated ~10–32 kya. We infer a population expansion in northeast Australia during the Holocene epoch (past 10,000 years) associated with limited gene flow from this region to the rest of Australia, consistent with the spread of the Pama–Nyungan languages.

(kya = thousand years ago). So about 10-32 thousand years ago, one group of Australians conquered all of the other groups of Australians.

The science article notes:

To the researchers’ amazement, the genetic pattern mirrored the linguistic one. “It’s incredible that those two trees match. None of us expected that,” says paleoanthropologist Michael Westaway of Griffith University, Nathan, in Australia, a co-author on the Willerslev paper. “But it’s confusing: The [genetic splits] date to 30,000 years ago or more but the linguistic divisions are only maybe 6000 years old.”

Willerslev says he first thought the languages must be much older than thought. “But the linguists told me, ‘no way.'”

Both types of data also show that the population expanded from the northeast to the southwest. This migration occurred within the last 10,000 years and likely came in successive waves, Bowern says, in which existing languages were overlaid by new ones. This expansion also seems to correspond with a stone tool innovation called a backed edge blade. But the accompanying gene flow was just a trickle, suggesting that only a few people had an outsize cultural impact, Willerslev says. “It’s like you had two men entering a village, convincing everyone to speak a new language and adopt new tools, having a little sexual interaction, then disappearing,” he says. Then the new languages continued to develop, following the older patterns of population separation. “It’s really strange but it’s the best way we can interpret the data at this stage.”

Three things going on here. 1. The group from the north conquered the group from the south, raped their women, and imposed their language. They were able to do this because they had better weapons (“backed edge blades.”) But the group from the north was not very big, and so did not leave a very big genetic signature.

2. They conquered an existing population structure, at which point their language got absorbed into that structure, probably picking up some linguistic substrate from the groups’ previous languages along the way. Since most people learn language from their parents, it’s not too surprising to find cases where language and genetics line up. (Note that people do not always learn languages from their parents.)

3. Intellectuals are kind of naive.

The other really interesting thing here is that the linguistics team came to their conclusions by feeding a big database of Aboriginal words into a computer and having it run similar algorithms to the ones geneticists use for examining human ancestry (see the lovely graphics above.) I’ve been wondering for a long time why they don’t just do this, and am excited that they finally are.

Now please someone put all of the languages + reconstructed proto-langauges into the computer and find the most likely trees.

(Sorry, Nick. The regularly scheduled Anthropology Friday is going to have to wait a week. There just aren’t enough days.)
