Koalas’ population comeback may be doing more than boosting numbers—it could also be rebuilding their lost genetic diversity.

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

Knowing how human DNA changes over generations is essential to estimating genetic disease risks and understanding how we evolved. But some of the most changeable regions of our DNA have been ...

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 ...

A strange tiny species of crustacean has challenged the way we think about natural selection and evolution. This microscopic animal, known as a water flea or Daphnia pulex, generates genetic variation ...

It's long been assumed that koalas in southern Australia are genetically unhealthy. A new study finds they're actually recovering, changing how scientists look at genetic risks.

A new Yale study provides a fuller picture of the genetic changes that shaped the evolution of the human brain, and how the process differed from the evolution of chimpanzees. For the study, published ...

Fish caught in the same trawl and sold under the same name may in fact have significant genetic differences. Beneath the surface of the Skagerrak lies a biological diversity that is rarely seen in ...

Surprising animal behaviors, from birds to amphibians, are revealing deep biological processes. Scientists are uncovering how viruses manipulate cells, how the immune system balances defense, and how ...
