Wild scarlet monkeyflowers in California survived a historic drought by relying on a rapid evolution, marking the first time the process has been observed in the wild.

A potted scarlet monkeyflower would die within a few days without water. But multiple natural populations of the species ...

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 ...

In a first-of-its-kind experiment tracing evolution across 25 generations, scientists have discovered that marine copepods—the tiny crustaceans at the heart of the ocean food web—rely on a largely ...

University of Vermont Professor Melissa Pespeni led a research team that explored how tiny sea creatures evolve. Her discovery provides hope that organisms in the ocean my be more resilient to the ...
