Adaptive evolution arises when heritable genetic variation confers a fitness advantage under changing environmental or ecological conditions. Central mechanisms include the generation of variation ...

Some scientists say humans may be entering a new phase of evolution, one in which culture is becoming more powerful than genes in shaping our survival and future. At the heart of that idea is a ...

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 ...

Researchers at the University of Maine are theorizing that human beings may be in the midst of a major evolutionary shift—driven not by genes, but by culture. "Human evolution seems to be changing ...

1 The extinction vortex, is genetic variation related to extinction?; 2 How to measure genetic variation; 3 Inbreeding, geographic subdivision, and gene flow; 4 Genetic diversity in changing ...

On Sept. 17, researchers reported the formal identification of Leopardus tilcayo, a small wild cat from Bolivia’s Yungas cloud forests. The study, published in Current Biology, marks the first ...
