This is the blog for GW students taking Human Evolutionary Genetics. This site is for posting interesting tidbits on: the patterns and processes of human genetic variation;human origins and migration; molecular adaptations to environment, lifestyle and disease; ancient and forensic DNA analyses; and genealogical reconstructions.

Biological sex tweaks nervous system networks, plays role in shaping behavior



We know that there are sex-based differences to certain behaviors and neurological responses, but the mechanisms behind these differences has been largely a mystery. This study examined those mechanisms using the roundworm (C. elegans) and found that there are differences in the control and function of neural circuits based on sex that can modify behavior. These differences have genetic underpinnings that could relate to neural development, behavior, and susceptibility to diseases.
