The evolutionary trajectories of complex traits are constrained by levels of genetic variation as well as genetic correlations among traits. As the ultimate source of all genetic variation is mutation ...

Science education reform continually occurs through the replacement of current teaching methods with alternatives that are designed to enhance student performance. Newly adopted teaching strategies ...

Researchers from the University of Chicago have demonstrated that natural selection plays a much larger role in molecular evolution than anyone suspected. Their report, published in the February 28 ...

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 ...

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 ...

"Survival of the fittest" is the catch phrase of evolution by natural selection. While natural selection favors the most fit organisms around, evolutionary biologists have long wondered whether this ...

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 ...

In a new paper published by Science, Alexey Kondrashov, Professor of Ecology and Evolutionary Biology at the University of Michigan, along with the co-authors of the study, have proposed that a ...
