Genomic model suggests population decline in human ancestors

A genomic model by Wangjie Hu and colleagues reveals a severe population bottleneck in human ancestors between 800,000 and 900,000 years ago, with only 1280 breeding individuals surviving. The decline coincided with climate changes, droughts, and glaciations, resulting in the loss of 98.7% of the ancestral population.
