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.

Forensic identification of age using methyl tags
A new paper in the journal Epigenetics suggests methyl tags for specific genes (e.g. ELOVL2 ) are highly correlated with age. This could provide a diagnostic tool - more precise/feasible than telomeres - for estimating the age of a suspect in forensic phenotyping. Perhaps similar assays could be developed for estimating age in wild primates!
