Scientists believe it contributed to a key evolutionary event\u2014chromosome fusion\u2014which may have set Homo sapiens apart from earlier hominin species, including Neanderthals and Denisovans. The study raises intriguing questions about how this small population survived, possibly through early fire use and adaptive intelligence. Understanding this ancient crisis helps scientists piece together the story of human evolution and the resilience that allowed our species to thrive against all odds.<\/p>\n<p>Learn more.<\/p>\n<hr>\n<div class=\"more-link-wrapper\"> <a class=\"more-link\" href=\"https:\/\/lifeboat.com\/blog\/2025\/03\/early-ancestral-bottleneck-couldve-spelled-the-end-for-modern-humans\">Continue reading \u201cEarly ancestral bottleneck could\u2019ve spelled the end for modern humans\u201d | &gt;<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Humanity came close to extinction 800,000 years ago.
