Pan troglodytesFLICKR, HANS HILLEWAERT

Species: Pan troglodytes; P. paniscus
Genome size: 3 billion base pairs; 2.9 billion base pairs

Both sequenced in the last two years, the common chimpanzee (Pan troglodytes) and bonobo (P. paniscus) genomes have shed enormous light on the evolutionary history of the great apes. To understand their evolution in even finer detail, a team led by investigators at The Salk Institute for Biological Studies in La Jolla, California, presents in Nature today (October 23) an analysis of human, chimpanzee, and bonobo induced pluripotent stem cell (iPSC) genomes.

Analyzing chimp and bonobo iPSC genomes, the researchers found greater expression of L1 transposons in both primates, as compared with humans. Overall, though, the team found that human, chimp, and bonobo iPSC genomes share nearly 98 percent of ...
