Researchers have sequenced the genome of the rhesus macaque, providing more precise data on how humans are genetically different from primates. Sequencing the macaque genome not only benefits research in human health but expands the understanding of primate evolution. More than 170 scientists from 35 institutions worked on the macaque genome project, and they published their findings in several articles in the April 13 issue of Science, a special edition devoted to the discovery.
