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 ...

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

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

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 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 ...

Volcanic eruptions on the remote island of Nishinoshima repeatedly wipe the land clean, giving scientists a rare chance to study life’s earliest stages. Researchers traced the genetic origins of an ...

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 ...
