New results emerging from graph theory prove that the way a population is organized can guarantee the eventual triumph of natural selection — or permanently thwart it. Natural selection has been a ...

A team of scientists has developed an algorithm that can accurately pinpoint, in large regions of the human genome, mutations favored by natural selection. The finding provides deeper insight into how ...

Investigators report that, as a species, humans are able to keep the accumulation of damaging mutations in check because each additional mutation that's added to a genome causes larger, and larger ...

As mutation affects essentially every aspect of biology, the development of a unifying theory for mutation-rate evolution is highly desirable. There is much to be explained. For although the ...

At this time of year, firemoths (Schinia masoni) can be seen on blanketflower (Gaillardia aristata), a colorful native wildflower. Evolution is the change of genetic forms in a population. We are ...

Evolution is such a slow process that it can be easy to be fooled into thinking it's not still happening. But certain populations of fish and geckos have adapted to changing environments in a span of ...

Professor of Evolutionary Genetics at The Milner Centre for Evolution, University of Bath Modern medicine’s ability to keep us alive makes it tempting to think human evolution may have stopped. Better ...

At this time of year, firemoths (Schinia masoni) can be seen on blanketflower (Gaillardia aristata), a colorful native wildflower. This is a fine example of crypsis, for the moth must sit with its ...
