Use of genes shapes difference between humans, chimps: scientist
AFP, April, 2004
BERLIN (AFP) — Chimps and humans differ by only a tiny percentage in their genetic make-up, but the reason why they're in trees and we're not lies in who has the most active genes, a leading scientist said.
Svante Paabo, who has been helping to decipher the genetic code of chimps, said the key lies in the degree to which genes are used in each species.
Human and chimpanzee genomes differ by just 1.2 percent, he told the annual meeting in Berlin of the Human Genome Organisation.
Yet around 10 percent of the genes are differently active, said Paabo, who studies at the Max Planck Institute for Evolutionary Anthropology in Leipzig, eastern Germany.
Among humans, the gene responsible for our sense of smell ...
