Unlike some, I find no problem with the idea of hybrids between ancestors of chimpanzees and humans. We have to assume that any speciation event will be protracted. The collection of genes that separate humans from apes would hardly have arisen in a single individual. From my study of dabbling ducks, I have come to […]

Evolution’s DNA Difference: Noncoding gene tied to origin of human brain
Investigators have discovered a gene that shows signs of having evolved rapidly in people and of having made a substantial contribution to the emergence of a uniquely human brain.

Letters from the July 15, 2006, issue of Science News
People want to know “Sharing the Health: Cells from unusual mice make others cancerfree” (SN: 5/13/06, p. 292) reported that years ago it was discovered that certain male mice eradicate cancer cells and that white blood cells from these mice make normal mice cancer resistant. It also reported that it is superpremature to look forward […]

Chimps creep closer yet
Humans evolved most slowly of all primates, with chimps a close second.

Well-Tooled Primates
People may have leaned on ancient primate-brain capacities to begin making stone tools by 2.5 million years ago, a transition that possibly spurred the development of language and other higher mental faculties.

Chimps ape others to learn tool use
Chimpanzees appear to develop traditions of tool use by copying one another's behavior and conforming to a successful approach.
