Truth Is Out There . . .

By Maggie Fox, Health and Science Editor

WASHINGTON (Reuters) - Researchers have sequenced DNA from the leg bone of a Neanderthal man who died 38,000 years ago and said on Wednesday it shows the Neanderthals are truly distant relatives of modern humans who interbred rarely, if at all, with our own immediate ancestors.

They estimate that modern humans and Neanderthals split from a common ancestor at least 370,000 years ago, and possibly 500,000 years ago, although we share 99.95 percent of our DNA.

“We see no evidence of mixing 40,000, 30,000 years ago in Europe. We don’t exclude it, but see no evidence,” Edward Rubin of the U.S. Department of Energy Joint Genome Institute in Walnut Creek, California, who led one study, told reporters.

This conflicts with some evidence from other researchers, including a team who said earlier this month that humans may have inherited a brain gene from Neanderthals.

The researchers reported their findings jointly in the journals Nature and Science.

Rubin’s team used one method to isolate and sequence part of the Neanderthal’s DNA, while another team, led by Svante Paabo of the Max Planck Institute for Evolutionary Anthropology, Leipzig, Germany, used a separate method to sequence a much larger amount.

Paabo was the first scientist to find and sequence Neanderthal DNA, in 1997, and first suggested that Neanderthals did not mix with modern humans.

“I think the sequence data will serve as a DNA time machine that will tell us about biology and aspects that we will never be able to get from their bones and a limited number of associated artifacts,” Rubin said.

Hell with the sprints! Look at the sports administrators to see how little we’ve evolved!

I am wondering how reliable a sample of DNA from 38,000 years ago is. T. Lindahl, ‘Instability and decay of the primary structure of DNA’, Nature 362(6422):709–715, 1993. S. Pääbo himself has found that DNA fragments a few hours after death into chains 100–200 units long, that water alone would completely break it down by 50,000 years, and that background radiation would eventually erase DNA information even without water and oxygen, ‘Ancient DNA’, Scientific American 269(5):60–66, 1993.

While you’re checking the scientific literature, if humans are 99.5 percent the same as Neanderthals, how close are ultimate fighters?

I can’t speak for the research, but from experience I would have to say that they (myself included) are a different species altogether. The trouble is is that there are enough groupies out there that over the years we have managed to mate and produce offspring. The scientific name I believe is Homo Antisocius. Here is a mnemonic to help coaches interested in coaching this sport to recognize potential Ultimate fighters:


* C - cannot follow law
* O - obligations ignored
* R - remorselessness
* R - recklessness
* U - underhandedness
* P - planning deficit
* T - temper

Are you sure Neanderthals could spell mnemonic?
