Because same-sex sexual behavior does not result in offspring, evolutionary biologists have long wondered how the genes associated with this behavior have persisted in the human genome, and whether ...

A wild cannibalistic sexual behavior in spiders has a simple genetic explanation, new study finds.

The Australian redback spider (Latrodectus hasselti), a cousin of the North American black widow spider, is known to practice sexual cannibalism, which is somewhat common among spider species. However ...

How do genes and the environment come together to shape animal behavior? Both play important roles. Genes capture the evolutionary responses of prior populations to selection on behavior.

Although sedentary behavior may be an evolutionarily selected trait, it is still important to try to be physically active, says a new study conducted at the University of Jyväskylä, Finland.

Humans have probably shared their homes with dogs ever since they first settled. So it could be argued that there is no such thing as “human society” without including animals as part of it. Our long ...

Although sedentary behavior may be an evolutionarily selected trait, it is still important to try to be physically active, says a new study conducted at the University of Jyväskylä, Finland.

Male Australian redback spiders perform an acrobatic somersault during mating that sends their abdomen directly toward the ...

We no longer believe in inherited capacities, talent, temperament, mental constitution, and characteristics. Give me a dozen healthy infants, well-formed, and my own specified world to bring them up ...

LONDON — A report released on October 2 by the Nuffield Council on Bioethics assesses the influence of genetics on patterns of behavior. It calls for intelligent use and regulation of genetics. The ...

Social behaviour can be pretty complex at the best of times, and defining the underlying genetic events has provided a formidable challenge. In the November 15 Sciencexpress, Michael Krieger and ...
