The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...

Researchers have significantly expanded the catalogue of known human genetic variation. The resulting datasets, shared in two back-to-back publications in the journal Nature, constitute what may be ...

Daphnia pulex (a.k.a. the water flea) is a microscopic crustacean whose unique reproduction habits make it the perfect species for studying evolution and natural selection. A new study looks at how ...

A study expands the list of known genes with circadian variation and provides the first comprehensive list of genes with seasonal variation in each tissue. Tissues in the thoracic cavity, such as the ...

Gene banks worldwide make an important contribution to the conservation of biological diversity. In addition to negative traits, old and exotic varieties possess many valuable gene variants that have ...

Several genetic variants associated with social behavior in honey bees are located within genes that have previously been linked to social behavior in humans, Ian Traniello at the University of ...
