Around 800-900k years ago, early humans faced a severe population bottleneck, dropping to ~1,280 breeding individuals. Genetic studies suggest it was caused by extreme climate shifts during a glacial period, nearly leading to extinction.

Around 900,000 years ago, during the Middle Pleistocene, early human ancestors faced a severe population bottleneck. Genetic evidence shows the breeding population dropped to about 1,280 individuals, nearly causing extinction—likely due to extreme climate changes like glaciations. Fascinating evol...

Around 800,000-900,000 years ago, a severe population bottleneck reduced early human ancestors to about 1,280 breeding individuals, lasting ~117,000 years. Likely caused by intense climate changes, like prolonged glacial periods, leading to drought and food scarcity. We survived, but it was a close ...

Around 900,000 years ago, a severe genetic bottleneck reduced the human ancestor population to ~1,280 breeding individuals, likely due to extreme climate changes like glaciation and drought. This nearly caused extinction but our lineage survived.

Around 800,000-900,000 years ago, early human ancestors faced a severe population bottleneck, dropping to ~1,300 breeding individuals. Likely caused by climate shifts, like a prolonged ice age, leading to habitat loss and resource scarcity. This is based on genomic studies from 2023.
