Stabilizing selection is a key evolutionary mechanism for which there is relatively little experimental evidence. To date, stabilizing selection has never been observed at the whole-genome level. We ...

Quantitative traits show abundant genetic, environmental, and phenotypic variance, yet if they are subject to stabilizing selection for an optimal phenotype, both the genetic and environmental ...

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 ...

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.

Evolution can perform spectacular makeovers: today's airborne songbirds descended from the wingless, earthbound dinosaurs that roamed millions of years ago, for example. But some organisms seem to ...

Hokkaido University researchers are finding evidence of natural selection that maintains the status quo among ant populations. A type of natural selection, called "stabilizing selection", is thought ...
