Orangutan DNA more diverse than human’s, remarkably stable through the ages
An international team of scientists, led by Washington University School of Medicine in St. Louis, has decoded the DNA of a Sumatran orangutan. With this genome as a reference, the scientists then sequenced the genomes of five additional Sumatran and five Bornean orangutans, they report in the journal Nature.
Don’t call it fur!
Chimpanzees don’t need haircuts.Mammals have fur over most of their bodies, but at some point during evolution, we humans lost that fur covering. Researchers at Washington University School of Medicine in St. Louis argue that hair on the head is somehow different from fur because fur stops growing when it reaches a certain length, but our head hair continues to grow.
