The chimpanzee represented the first non-human primate sequenced. The differences in the chimpanzee and human genomes are small, with 99% of the DNA sequence preserved. <ref>http://www.nih.gov/news/pr/aug2005/nhgri-31.htm</ref> The differences can be classified in terms of differences in local single nucleotide substitutions, insertions, deletions and repetitions of sequences. A relatively large number of difference between the chimpanzee and human genomes are not due to substitutions.<ref>http://207.210.67.162/~striz/docs/chimpc.pdf</ref> When this is taken into account, humans and chimpanzees still share 96% of their sequence, and are genetically closer than rats and mice.<ref>http://www.nih.gov/news/pr/aug2005/nhgri-31.htm</ref> | The chimpanzee represented the first non-human primate sequenced.
