Human evolution not from chimps, fossil study confirms

Our ancestors underwent a previously unknown stage of evolution over more than a million years before “Lucy”, the iconic early human ancestor specimen that walked the Earth 3.2 million years ago,” National Geographic Magazine science editor Jamie Shreeve reports today.science-cover-image.jpg

The finding, published in tomorrow’s journal Science, is based on the discovery of the oldest fossil human skeleton, a small-brained, 110-pound (50-kilogram) female of the species called Ardipithecus ramidus.

“The fossil puts to rest the notion, popular since Darwin’s time, that a chimpanzee-like ‘missing link,’ midway resembling something between humans and today’s apes, would eventually be found at the root of the human family tree,” Shreeve writes.

“Indeed, the new evidence suggests that the study of chimpanzee anatomy and behavior, long used to infer the nature of … the earliest human ancestors, is largely irrelevant to understanding our beginnings.”

Walking for sex

Jamie Shreeve also launched his new blog today with a related piece on Ardi’s sex life. (Ardi is the name scientists have given this fossil).

It is fascinating reading, “especially if you like learning why human females don’t know when they are ovulating, and men lack the clacker-sized testicles and bristly penises tk sported by chimpanzees,” Shreeve writes. Read the rest of this at:

Did early humans start walking for sex?

Science is publishing 11 different papers about the Ardi research, involving more than 40 different authors.

In this 200th anniversary year of Darwin’s birth, Science is pleased to publish the results of many years of scientific research that suggest an unexpected form for our last common ancestor with the chimpanzees,” writes Bruce Alberts, Editor-in-Chief of Science, in an editorial about the research.

“The history of science assures us that powerful new techniques will be developed in the coming years to accelerate such research, as they have been in the past,” Alberts writes. “We can thus be certain that scientists will eventually obtain a rather detailed record showing how the anatomy of the human body evolved over many millions of years.”

    Scientists have *never* claimed that humans evolved from chimps – both humans and chimps evolved from a common ancestor species. And it has been a common assumption that the common ancestor species would be much more chimp-like than human-like, ie not halfway between the two. So there has never been “[a] notion […] that a chimpanzee-like ‘missing link,’ midway resembling something between humans and today’s apes, would eventually be found at the root of the human family tree”.

    It is a pity that such poorly worded articles from a respected source such as National Geographic only gives fodder to those that don’t accept evolution as a fact – as attested by other comments on this post.
