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 ...

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 ...

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

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 ...

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

For more than 50 years, scientists have been freezing living cells from endangered species. Here’s how the Frozen Zoo® is ...

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

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 ...

Structural variants (SVs) are alterations in the DNA sequence that involve large-scale changes, typically longer than 50 base pairs. Advances in long-read sequencing have significantly increased ...
