Why
Researchers at the University of Sydney and Texas A&M mapped the koala's population history over roughly the past 100,000 years and concluded that climate shifts caused the species' first major collapse.
The Frontline Impact
How this affects you
This finding changes how conservationists understand the risks koalas face, as their DNA could reveal their resilience and how little room there is for additional pressure from habitat destruction, disease, and fire. Better genetic tracking could help officials intervene earlier to prevent further population decline and inbreeding.
