Just like the moths in europe that were in my old textbooks. The moths got darker as the pollution/soot got on the trees and made the trees darker. And now that the pollution problems (from the 50's and 60's), the trees are lighter and the moths are getting lighter.
Actually the moths themselves have always been the same color. Its just the NUMBER of moths of "each" color that had changed. Just like these birds.

their beaks revert to an intermediate size
So now the birds have a smaller pecker?

So now they're
devolving into a
lower lifeform?
We are DEVO. D-E-V-O.
(But seriously, this just shows variation about the genetic mean, which is all that's ever been observed.)

The only answer is for human beings to exterminate themselves so that large-beaked finches may survive and flourish.
To: mlc9852
Ahh, micro-evolution at it's best.

I've always thought of the left wing fringe as devolved; the RAT party seems to be devolving - its the only rational explanation for the elevation of Nancy Pelosi....

Human interaction with animals could be causing evolution to go into reverse... Sigh.

I really don't have anything to add, except the source of this is from an aljazeera.net server? I thought that area of the globe stopped evolving arround 800 years ago.

I see Nancy as more of a deletorious mutation. In nature 99% of all mutations are fatal. We weren't that lucky in her case :)
To: raynearhood
Al-jazeera has a lot of news about all sorts of things. Of course, it's always better to have more than one source.
