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.
A fundamental goal in biology is to predict the evolution and optimization of traits in populations undergoing natural selection. Quantitative genetics has emerged as the dominant paradigm for ...
FACTORS OF EVOLUTION : THE THEORY OF STABILIZING SELECTION BY II SCHMALHAUSEN TRANSLATED BY ISADORE DORDICK EDITED BY THEODOSIUS DOBZHANSKY WITH A NEW FOREWORD BY DAVID B WAKE ...
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 ...
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 ...
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 ...
