What about Finches named Dennis? ;-)

This might be true, but has our sun gone supernova yet?
Evolutionary changes occur with each generation. They don't usually create observable morphological changes.
Is this pre-emptive commentary?
Or maybe it's post-emptive; based on comments on prior threads?
You nailed it Widewake. Evolution is a theory about speciation. As in the "Origin of Species". Changing bill-size over generations is not - in itself - speciation.
Al Gore says this won't save them. They are all doomed.
Any genetic population shift is evolution. They describe how this finch population has undergone evolution due to competition - which hasn't been observed before.
People saying "ah but has [something else entirely] happened yet?" are reading something into this article that isn't there while simultaneously missing what is there. Quite a feat.
Maybe, but we won't know it for seven minutes.

IOW, Natural Selection.
Evolution is not a theory soley about speciation. It covers any genetic change in a population. Ie bacteria can evolve resistance to antibiotics even though they haven't changed species.
Nope, the finch aren't becoming anything else. They're still finch. A taller human is still a human -- and this isn't evolution any more than that... Now when the finch turns into a frog, ping me. That's evolution.
see #30
The REAL reason AP is reporting this is to counter the facts in Ann Coulter's book relating to the wacko-evolutionists and the creation argument. She mentioned the finches as another example of Darwinian argument errors.
Still the same species
LOL Gee, the sizes of the finch beaks has been a 'proof' of evolution for evol believers for a long time. Apparently, these birds change beak sizes like I change my shoes.
Coulter just repeats the anti-evolution literature, probably off some website or other. It's all nonsense. Many of the problems they cite with Darwin's finches are problems they have imagined through their lack of understanding of the matter.
how does a shorter beak equate to evolution? it could easily be attributed to global warming or more likely a statistical fluke in the measurements themselves.
Yeah, you coulda knocked me over with a ... no, I can't do it.
im not aware of anyone using finches as a "proof" of evolution. It's a demonstration of natural selection.
A fair clarification. But the word "Darwin" in the title kind of throws the theory of speciation into the ring :0)
