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 ...

The loca arginine vasopressin receptor la (avpr1a) and oxytocin receptor (oxtr) have evolutionarily conserved roles in vertebrate social and sexual behaviour. Allelic variation at a microsatellite ...

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.

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 ...

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 ...

Why does natural selection appear to happen slowly on long timescales and quickly on short ones? A multigenerational study of four lizard species addresses biology’s “paradox of stasis.” James Stroud ...
