In their efforts to identify the genetic basis for differences in mate choice that keep two co-existing species of butterfly separate, evolutionary biologists at Ludwig-Maximlians-Universitaet (LMU) ...

Group size and mating preferences may have caused male primates, including humans, to evolve deeper voices than females. The findings can help to shed light on social behavior in humans and their ...

NOTE: The embargo for this release has been lifted. A biologist at Washington University in St. Louis has shown that for some fish species, females prefer males with larger sexual organs, and actually ...

People tend to focus on Darwin’s ideas about natural selection, but he also spent a portion of The Origin of Species discussing another powerful evolutionary force: sexual selection. If a species ...

New research has revealed that sexual arousal leads to an immediate preference in short-term mating in men over more long-term committed relationships, such as marriage. Short-term mating preferences ...

According to an article by Schwarz and colleagues, published in the June 2020 issue of Evolutionary Psychological Science, men and women have significantly different mating preferences. 1 To ...

Major histocompatibility complex (MHC) genes are known to mediate sexual selection both at the individual and gamete level. Previous studies have shown that perceived body odor attractiveness is ...

The human genome is a complex record of migration, evolution, and ancestry written over thousands of millennia. Now, new genomic research by members of Sarah Tishkoff’s lab at the University of ...
