    Ancient Climate Crisis Nearly Erased Humanity

    Miglior citazione da Ancient Climate Crisis Nearly Erased Humanity

    “

    Our ancestors experienced a 'bottleneck' where the breeding population crashed to just about 1,280 individuals, a 98.7% reduction that lasted for around 117,000 years. It suggests the very traits that make us uniquely human—like advanced cooperation and innovation—might have been forged in the crucible of near-extinction.
