Koalas Crashed Once Before: Genomic Study Dates a 100,000-Year-Old Population Collapse
A genomic study reveals koalas suffered a severe population collapse around 100,000 years ago, driven by climate upheaval before humans arrived in Australia. Modern koalas descend from a single surviving population, and understanding this ancient history is key to addressing current human-caused threats.
