Koala population crash came before humans, genomic study reveals

A genomic study shows that koalas faced a significant population decline approximately 100,000 years ago, long before human arrival in Australia. This finding challenges previous assumptions about the factors influencing koala population changes. The research highlights the role of natural environmental shifts in shaping koala history. The discovery provides new insights into the species' resilience and adaptation over time.
