The most comprehensive genomic study ever on primates - a group whose membership includes lemurs, monkeys, apes and people - has revealed pivotal genetic traits that are uniquely human while refining the timeline for our evolutionary lineage's split from our closest cousins, the chimpanzees and bonobos.
Researchers said on Thursday they sequenced and analyzed the genomes of 233 primate species, comprising nearly half of those alive today, and surprisingly discovered that most boast greater genetic diversity - variation within a species that is vital for adaptation to changing environments and other challenges - than humans.
