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 ...

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 ...

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 ...

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 ...

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 ...

Another complication is that sustained genetic variation does not emerge exclusively as a result of natural selection.

Modern medicine’s ability to keep us alive makes it tempting to think human evolution may have stopped. Better healthcare disrupts a key driving force of evolution by keeping some people alive longer, ...
