The Flood
Chapter summary from Sapiens by Yuval Noah Harari.
When sapiens expanded into new regions, the landscape did not merely gain a clever ape. It lost creatures that had survived ice ages and volcanoes for millions of years.
Australia and the Americas show a recurring pattern: large animals disappear soon after humans arrive, and the sequence repeats across islands and continents. Coincidence becomes harder to defend when the timeline keeps matching footprints.
Alongside this comes another disappearance: other human species. Neanderthals, Denisovans, and others vanish, leaving a single branch where there were once several. Whether through competition, absorption, or violence, the result is the same: one species inherits the planet.
Power begins here as ecology. Dominance is not only building temples. It is also deciding, often unintentionally, which lives continue and which become fossils.
A 30-second summary — and that's the point. Read Stacks chapters are deliberately short. The full Sapiens edition has the examples, the longer argument, and the moments worth re-reading. If this resonated, the Bookshop link below supports the author and an indie bookstore.
