Pittsburgh Professors Challenge Darwin
Syberghost writes "Darwin's Theory of Evolution comes under an interesting attack from an American anthropologist and an Italian biochemist, according to an article from University of Pittsburgh's school newspaper. In a nutshell, Schwartz and Maresca argue that change is not gradual as Darwin stated, but comes rapidly in response to drastic mutations caused by shifting environmental conditions."
On another note, Darwin supports his theory of evolution. He looks like a monkey!
After all, I am strangely colored.
...when Gould came up with it 20 years ago.
Seriously, is the author of TFA a moron or what? Punctuated Equilibria is not the same as "Science is wrong!!!11one"
The actual article is available from The Anatomical Record Part B: The New Anatomist" volume 289B, Issue 1 , Pages 38 - 46. The abstract's free, although the article itself may require a subscription or university account. The flareup seems to be with this sentence in the abstract (I haven't read more yet): "In evolutionary terms, extreme spikes in environmental stress make possible the emergence of new genetic and consequent developmental and epigenetic networks, and thus also the emergence of potentially new morphological traits, without invoking geographic or other isolating mechanisms." In other words, a change in the environment puts organisms under extreme stress, overloading the ability of various DNA repair mechanisms to counteract DNA damage and mutation, occasionally resulting in novel, beneficial mutations. Several other posters have already said this really isn't anything new, for instance it's known that some bacteria actively mutate their DNA in response to extreme environmental stress. The author (Schwartz) may be hyping his claims some, but really it looks like a case of the reporter going gonzo, and might be a creationist yahoo to boot.
