Evolution is perhaps the most extraordinary story ever told—a tale spanning billions of years that connects every living thing on Earth through an intricate ...

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Using advanced analysis based ...

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

A new study published in Science is challenging long-held assumptions about how we measure genetic risk in endangered species ...

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

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

A study combining the growing number of ancient genomes from living people has given us our best picture yet of how humans have evolved over the past 10,000 years or so. It shows that people in ...

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.

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 ...

When a nuclear disaster empties a landscape of people, nature doesn’t politely wait for instructions. It moves in. After the ...
