Beringia is the now-lost land between Alaska and Russia that was, during the last ice age, a vast grassland. It is believed that humans lived here for thousands of years, hunting mammoths, woolly rhinos, bison, and equines. The probably fished as well, just like modern humans in the area.
It was a land of frigid abundance, of herds of giant beasts that probably put the buffalo to shame.
Here is a nice podcast by Razib and Spencer on the lost paradises of Beringia, Sundaland, and Doggerland.
Humans lived in Beringia for thousands of years before they made it into the rest of North America, because the rest of the continent was blocked off, then, by a giant impenetrable ice sheet. This period is therefore referred to as the “Beringia pause” because humans “paused” here during their migration from Siberia to the Americas, but this name obscures the lives and purposes of the people who lived here. They weren’t consciously trying to get to North America and pausing for thousands of years because their way was blocked; they were happily living their lives in a land of abundant resources. We could equally say that Europeans “paused” in Europe for thousands of years before some of them migrated to the Americas, or that anyone on Earth has “paused” in the place they are now.
According to an article published recently in Nature, The Population History of Siberia since the Pleistocine, by Martin Sikora et 53 other people, these folks in Beringia have their own interesting and complex population history, full of migration and back-migration, conquering, splitting, and joining:
Northeastern Siberia has been inhabited by humans for more than 40,000 years but its deep population history remains poorly understood. Here we investigate the late Pleistocene population history of northeastern Siberia through analyses of 34 newly recovered ancient genomes that date to between 31,000 and 600 years ago. We document complex population dynamics during this period, including at least three major migration events: an initial peopling by a previously unknown Palaeolithic population of ‘Ancient North Siberians’ who are distantly related to early West Eurasian hunter-gatherers; the arrival of East Asian-related peoples, which gave rise to ‘Ancient Palaeo-Siberians’ who are closely related to contemporary communities from far-northeastern Siberia (such as the Koryaks), as well as Native Americans; and a Holocene migration of other East Asian-related peoples, who we name ‘Neo-Siberians’, and from whom many contemporary Siberians are descended. Each of these population expansions largely replaced the earlier inhabitants, and ultimately generated the mosaic genetic make-up of contemporary peoples who inhabit a vast area across northern Eurasia and the Americas.
There is a lot of interesting material in this paper (and some nice maps and graphs), but I’m too tired to summarize it all and not lose accuracy, so I encourage you to read it yourself; perhaps the most interesting part involves migration from Alaska to Siberia, across the now-Bering Strait, of people like the Ekven (are these the same as the awkwardly named Evens?)
The polar world is a fascinating circle.
