Well, certainly more so than creatioists.  :D

It is time to stop thinking we are the pinnacle of evolutionary success chimpanzees are the more highly evolved species, according to new research.

Evolutionary geneticist Jianzhi Zhang and colleagues at the University of Michigan in Ann Arbor, US, compared DNA sequences for 13,888 genes shared by human, chimp and rhesus macaques.

For each DNA letter at which the human or chimp genes differ from our shared ancestral form inferred from the corresponding gene in macaques researchers noted whether the change led to an altered protein. Genes that have been transformed by natural selection show an unusually high proportion of mutations leading to altered proteins.

Zhang's team found that 233 chimp genes, compared with only 154 human ones, have been changed by selection since chimps and humans split from their common ancestor about 6 million years ago.

This contradicts what most evolutionary biologists had assumed. "We tend to see the differences between us and our common ancestor more easily than the differences between chimps and the common ancestor," observes Zhang.

The result makes sense, he says, because until relatively recently the human population has been smaller than that of chimps, leaving us more vulnerable to random fluctuations in gene frequencies. This prevents natural selection from having as strong an effect overall.

And take nothing but a grip
With the few good books that really count
It's a necessary trip

I'll be gone with the girl in the gold silk jacket
The girl with the pearl-driller's hands

Then why do we still have humans?

OK, I'm not a biologist, but that article makes me want to puke.

One, the title.  "MOre evolved" makes your ordinary person in the street thing "superior".  Therefore no sensible and intelligent journalist should use that phrase unless it is precisely defined and essential to the story.
remember New Scientist gets syndicated or ripped off by a bunch of newspapers.

The first sentence then compounds the error, by mixing up a greater number of changes in the genome with the idea of success and superiority.  I can just see this article confusing people and perpetuating the supposed link between evolution and racism and eugenics.  

Whoever wrote it should come on this board and defend their poor writing.

Which, I suppose, explains why chimps are virtually extinct, and humans infest every habitable area on the entire planet.

This is "news."

Everybody should've been aware of this fairly obvious fact ever since Charlie "Fire Away" Heston climbed out of his capsule.

Just because the "wilder" chimps have mugged their way to entirely-evanescent short-term "success" over the "tamer" chimps, doesn't mean that our retiring forest-bound brothers will not triumph in the end.

It's destiny, I tell ya!

And you don't have to believe me, ask that time-traveling astronaut, Mr. Heston.
