A new study uses age-stratified allele frequencies to map ongoing natural selection and rare pathogenic variants.

Some of nature's mysteries have kept scientists busy for decades—for example, the processes that drive evolution. The question of whether certain differences between and within species are caused by ...

New research suggests that natural selection, famous for rewarding advantageous differences in organisms, can also preserve similarities. The researchers worked with a plant called wild radish and its ...
