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.

New Possible Origin of Insect Wings

Researchers at the University of Florida have identified Hox gene regulation of abdominal wing serial homologs that may be used to elucidate the molecular mechanisms that lead to the development of insect wings. These researchers used the Tribolium beetle as a model organism to purpose a third possible evolutionary origin of insect wings that may unify the two most prominent current hypotheses. This third hypothesis was termed the dual evolutionary origin of insect wings. However, these researchers stated that further testing of the Hox regulation of these abdominal wing serial homologs is required to explore the dual evolutionary origin of insect wings hypothesis.
