We don't talk about this paper enough and the evidential risk it implies for the future. I guess this is what makes Elon and others worried (more likely from first principles thinking) This paper implies we were down to ~30k humans at one point: https:/

When we apply FitCoal, the inference method used by Hu et al. (https://t.co/Id13BMLJOO), to a model without an ancient, extreme bottleneck (black in Figure 1B), it artifactually produces a population size history with an extreme bottleneck (red in Figure 1

The human population was reduced by 99% about 900,000 years ago due to climate change and remained at that level for about 100,000 years. During this period there were about 1300 breeding individuals on average. In the entire world. https://t.co/8uuHVwUa0d

Fascinating study. If there had been a few hundred individuals less 900,000 years ago, I would not be here to comment on this study. Chance plays a massive role in the history of evolution. Nothing is a given https://t.co/hCIBspppCE
Between 800,000 and 900,000 years ago, the population of #human ancestors crashed, a 2023 Science study finds. The results suggest there were only ~1280 breeding individuals during the transition between the early and middle #Pleistocene. #momentomori
