The secret to chimp strength

Big differences in duplicated DNA distinguish chimp and human genomes
A study comparing the genomes of both humans and chimpanzees has found that much of the genetic difference between the two species came about in events called segmental duplications, in which segments of genetic code are copied many times in the genome. The study appears as a companion article to t...
