Ajit Varki and Pascal Gagneux from the University of California in San Diego,
who’ve been studying the known genetic differences between humans and our
primate cousins. The researchers claim that because we’re so similar, only full
sequencing of chimp DNA will tell us which genes make us human.
“If you were looking down from outer space and simply took the DNA
differences we would certainly fall into one group with the…
