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 ...

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 ...

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 ...

When most people think about natural selection, they imagine individuals competing with one another: The fastest animal escapes predators, the strongest plant produces more seeds, and the most ...

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 ...

Most of us know that as living things evolve, they take on traits that help them thrive in their home environments. But how are certain traits "chosen" for future generations, and how are others cast ...

Millions thrive at high altitudes due to remarkable genetic adaptations. Tibetans, for instance, possess a gene variant allowing efficient oxygen use without dangerously thick blood. Andeans and ...

A new study has highlighted how reproductive biology and human behavior influence the number of children a person might have. This research, which has identified genetic factors that impact human ...
