Comparing primate genomes offers insight into human evolution
...number in specific primate lineages. All the great ape
species showed more increases than decreases in gene copy numbers, but humans showed the highest number of genes with increased copy numbers, at 134, and many of these duplicated human genes are implicated in brain structure and function. Because som...

Organgutan numbers plummeting worldwide; species may vanish in ten years, study says
NEW YORK -- The orangutan - the only great ape
found in Asia - may vanish from the wild within a decade, unless illegal logging of its habitat and poaching can be greatly reduced, according to research funded by the Bronx Zoo-based Wildlife Conservation Society (WCS). The study, which appears in ...
We are family: the imperative for a chimpanzee genome project
