Evolution Not Just the Result of Random Mutations

The research, which appears to offer evidence of a hidden mechanism guiding the way biological organisms respond to the forces of natural selection, provides a new perspective on evolution, the scientists said.

The researchers -- Raj Chakrabarti, Herschel Rabitz, Stacey Springs and George McLendon -- made the discovery while carrying out experiments on proteins constituting the electron transport chain (ETC), a biochemical network essential for metabolism. A mathematical analysis of the experiments showed that the proteins themselves acted to correct any imbalance imposed on them through artificial mutations and restored the chain to working order.

"The discovery answers an age-old question that has puzzled biologists since the time of Darwin: How can organisms be so exquisitely complex, if evolution is completely random, operating like a 'blind watchmaker'?" said Chakrabarti, an associate research scholar in the Department of Chemistry at Princeton. "Our new theory extends Darwin's model, demonstrating how organisms can subtly direct aspects of their own evolution to create order out of randomness."

Does anybody else get a little warm, nostalgic feeling when they read a non-textbook that calls the mitochondria the "powerhouse of the cell" and talks about ATP? *sigh* It almost makes me giddy.

One very important point the article stresses:

The scientists do not know how the cellular machinery guiding this process may have originated, but they emphatically said it does not buttress the case for intelligent design, a controversial notion that posits the existence of a creator responsible for complexity in nature.

Not that the opinions of scientists hold any water with ID pushers. Especially when the scientists have conceded 2 points:

  1. it's a very complex process that's being "guided" on some level

  2. and

  3. they don't know how it's happening

Obvious answer - God did it. Duh.
