Ancient human species nearly swept to extinction, suggests gene analysis

  • Researchers discovered a severe population bottleneck from 813,000 to 930,000 years ago reducing ancestral human species to less than 1,300 breeding individuals.
  • The population reduction likely stemmed from climatic changes and aligns with prehistoric gaps in human fossil records in Africa and Eurasia.
  • This severe bottleneck may have sparked significant effects on hominin speciation, possibly marking a key event in the evolutionary lineage leading to modern humans.
