As koalas in southern Australia have grown from a few hundred to almost half a million, the marsupials show signs of regaining lost genetic variation.

Some koalas may recover their genes after major population crashes. Growing koala populations may rebuild genetic strength over time.

A new study reveals that habitat fragmentation can lead to sudden "tipping points" where a species' genetic health ...

If you follow media coverage of koalas, you could be forgiven for feeling confused. Recent stories describe a “koala paradox”: endangered in the north of Australia, abundant in the south; genetically ...

A new study published in Science is challenging long-held assumptions about how we measure genetic risk in endangered species. Researchers analyzed whole genomes from hundreds of koalas, finding that ...

Understanding biological relationships is often critical when studying animal populations. Researchers have now developed a transformative approach that identifies stretches of DNA that two ...

When a nuclear disaster empties a landscape of people, nature doesn’t politely wait for instructions. It moves in. After the 2011 meltdown at the Fukushima Daiichi nuclear power plant in Japan, ...

Tree genome evolution is a fascinating area in the study of biodiversity and ecosystem stability. Trees, with their distinctive life history traits, such as ...

Human evolution’s biggest mystery, which emerged 15 years ago from a 60,000-year-old pinkie finger bone, finally started to unravel in 2025. Analysis of DNA extracted from the fossil electrified the ...
