Koalas (Phascolarctos cinereus), such as this mother and 7-month-old joey from Queensland, Australia, embody a genetic paradox. Populations rich in diversity are declining, whereas those with little variation are expanding and rapidly reshuffling their genomes. These findings reveal that diversity alone does not determine resilience. Instead, a population’s fate depends on several evolutionary processes unfolding across generations.

According to a new study of Australia’s koala populations, rapid demographic rebound may be able to restore once-lost genetic variation and drive recombination in ways that re-establish long-term evolutionary potential in previously bottlenecked populations.
