Have the canines acquired strange mutations living near the power plant?

In five cases where vertebrates evolved monogamy, the same changes in gene expression occurred each time. In many non-monogamous species, females provide all or most of the offspring care. In ...

An understanding of the origin and dynamics of heritable genetic variation within classical animal breeding programs is needed to provide the context for understanding the contributions and concerns ...

A genetic “cheat sheet” allows different species to display the same warning patterns.

Evolution is a continuous, powerful force shaping the natural world around us. As environmental pressures intensify, future animal evolution is likely to produce fascinating and sometimes bizarre new ...

New research is shaking up our understanding of evolution by revealing that some species may not evolve gradually at all. Instead, scientists discovered that certain marine worms experienced an ...

Researchers at the University of Bristol have traced the genetic changes that allowed animals to colonize land not once but at least 11 separate times across the tree of life, finding that distantly ...

Add Yahoo as a preferred source to see more of our stories on Google. Once upon a time, there were a bunch of one-celled microbes, swimming, eating, reproducing, doing all the things that a one-cell ...

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Using advanced analysis based ...
