In natural populations, the mechanisms of evolution do not act in isolation. This is crucially important to conservation geneticists, who grapple with the implications of these evolutionary processes ...

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 ...

The study of genetic variation and growth traits in tree species is crucial for understanding the mechanisms that underpin forest productivity, resilience and adaptation. Recent advances in molecular ...

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

Erangi Heenkenda, co-lead author of the PNAS paper who received her PhD in forestry and natural resources from Purdue this month, prepares to take a sample from a frozen pupfish that will be used for ...

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 ...

Humans are still evolving, and Tatum Simonson, PhD, founder and co-director of the Center for Physiological Genomics of Low Oxygen at University of California School of Medicine, plans to use ...

When a species lives in two distinct types of habitats, individuals with traits better suited to each habitat will thrive and reproduce, naturally selecting descendants with those traits.
