Why chimps can't chatNovember 12th, 2009 LONDON - A mutation in a gene might help explain why chimps, our nearest relative, don't talk, claim scientists. It is known that when mutated, FOXP2 can disrupt speech and language in humans, and now the study has revealed major differences between how the human and chimp versions of the gene work, perhaps explaining why language is unique to humans.

'Addiction gene' puts white women at high risk of becoming drug, booze addictsSeptember 1st, 2009 LONDON - Scientists at Yale University have identified an 'addiction gene' that puts white women at high risk of drink or drug abuse. The finding paves way for a DNA test to screen for those people who are most at risk of becoming drug addicts or alcoholics.
Genetic analysis challenges human-chimp interbreedingAugust 29th, 2009 LONDON - A genetic analysis has called into question the controversial claim that early humans and chimpanzees interbred before splitting into separate species. In 2006, David Reich and his colleagues at the Broad Institute in Cambridge, Massachusetts, compared the genomes of humans, chimps and three other primate species, and found that the separation of ancient humans from our closest cousins was more complex than a clean break.
