Summary

Story summary

Kangaroo Island's koalas face genetic challenges from inbreeding and reduced diversity, despite being a conservation success.
Research shows their genetic legacy originates from fewer than 24 relocated koalas in the 1920s.
Extensive homozygosity indicates a compromised gene pool, raising risks of fertility issues and developmental abnormalities.
Researchers recommend introducing genetically diverse mainland koalas for better adaptability.
Ongoing genomic monitoring is crucial for long-term survival and global wildlife conservation strategies.
