Why
A new DNA study published in Molecular Biology and Evolution concluded that climate shifts, not early human activity, caused the koala species' first major collapse.
The Frontline Impact
How this affects you
The finding changes how conservationists understand the risks koalas face, suggesting their DNA could reveal resilience to climate-driven bottlenecks but also highlights vulnerability to modern human-caused pressures like habitat destruction and disease, which further impact ecosystems and local economies.
