An analysis of ancient and modern DNA suggests the extent of convergent evolution in different peoples around the world is even greater than we thought ...

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

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 ...

A large-scale genomic study of koalas across eastern Australia has found that populations that went through severe 20th-century bottlenecks are already showing signs of genetic recovery, challenging ...

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 ...

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.

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 ...

Jason Munshi-South joined the Drexel faculty in 2024 as the Betz Endowed Chair of Ecology and Professor in the BEES department. Jason’s research program is dedicated to understanding how wildlife ...
