For decades, many evolutionary biologists argued that natural selection acts primarily on individuals. In other words, that organisms are rewarded or penalized one at a time, and that the idea of ...

Evolutionary biology explores how living systems change over time through variation, inheritance and differential success. At its heart lies the concept of descent with modification: populations ...

A new paper in Molecular Biology and Evolution, finds that changes in animal development induced by climate shock persist ...

Mathematical model: The study shows that multicellularity can evolve without direct benefits over unicellular ancestors. In ...

A common element in “Star Trek” and other science fiction is their depiction of humanoid alien species. If life exists ...

Scientists have developed a theoretical model that uncovers the dual role of polyploidy -- organisms carrying extra genome copies -- in evolution. Their findings reveal that polyploidy can stabilize ...

The study of early vertebrates provides an essential window into the evolutionary processes that shaped modern biodiversity. Fossil discoveries spanning the Silurian to Devonian periods reveal a ...
