A type of natural selection, called "stabilizing selection," is thought to maintain functional characteristics in species. But it is difficult to find evidence of this type of selection through ...

Despite being a central issue in evolutionary biology, few studies have examined the stasis of characters in populations with no gene flow. A possible mechanism of such stasis is stabilizing selection ...

How are humans contributing to negative selection? It's a part of evolution that can also drive some species to extinction; models of negative selection help us understand biodiversity.

HOKKAIDO, Japan, Dec. 20 (UPI) --Scientists have previously hypothesized that evolutionary forces work to maintain a species' most functional physiological features. They call the process "stabilizing ...
