The survival of the human species in the face of high rates of genetic mutations has remained an important problem in evolutionary biology. While mutations provide a source of novelty for the species, ...

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 ...

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 ...

Population genetics theory supplies powerful predictions about how natural selection, interacting with genetic linkage, will sculpt the genomic landscape of nucleotide polymorphism. Genetic ...

Genetics is important to our understanding of selection for at least three reasons: first, although the concept of selection seems obvious, it was not until selection was linked to Mendelian genetics ...

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 ...

When Charles Darwin articulated his theory of evolution by natural selection in On the Origin of Species in 1859, he focused on adaptations — the changes that enable organisms to survive in new or ...

Joe Pickrell works for and holds equity in the personal genomics company Gencove. Molly Przeworski receives funding from the National Institute of Health. Hakhamanesh Mostafavi does not work for, ...

At this time of year, firemoths (Schinia masoni) can be seen on blanketflower (Gaillardia aristata), a colorful native wildflower. This is a fine example of crypsis, for the moth must sit with its ...

Investigators report that, as a species, humans are able to keep the accumulation of damaging mutations in check because each additional mutation that's added to a genome causes larger, and larger ...
