"A new article in Horizon, Ice-age Europeans roamed in small bands of fewer than 30, on brink of extinction (via Eurogenes), basically gives away the game in the headline. But please keep in mind my earlier post, as low effective population numbers may not accurately convey the actual census size over long periods of time. These results are not particularly surprising, as the ancient genomes we have from hunter-gatherers tend to indicate a very high level of inbreeding in comparison to modern populations. The main difference here is that it seems that they have more and more ancient genomes sampled from diverse locations to add confidence to the original conjecture:" - Maitani
