Diabetes risk gene 'from Neanderthals'

A gene variant that seems to increase the risk of diabetes in Latin Americans appears to have been inherited from Neanderthals, a study suggests.
We now know that modern humans interbred with a population of Neanderthals shortly after leaving Africa 60,000-70,000 years ago.
This means that Neanderthal genes are now scattered across the genomes of all non-Africans living today.
Details of the study appear in the journal Nature.
The gene variant was detected in a large genome-wide association study (GWAS) of more than 8,000 Mexicans and other Latin Americans. The GWAS approach looks at many genes in different individuals, to see whether they are linked with a particular trait.READ MORE
