In Nature this week, a team led by investigators at the Wellcome Trust Sanger Institute presents "the assembly and analysis of a genome sequence for the western lowland gorilla," and proposes "a synthesis of genetic and fossil evidence consistent with placing the human-chimpanzee and human-chimpanzee-gorilla speciation events at approximately 6 and 10 million years ago." Further, the team reports having found that in 30 percent of the genome, "gorilla is closer to human or chimpanze
