Let me say this again for those who have not learned the wisdom of Truth. Don’t just study the finches but in general; Look at the birds in the air, they do not sow or reap or store away in barns for the Heavenly Father feeds them. That’s from a book more than 2000 years ago. When one understand the Theo, who cares about the Theo-ry?

In reply to Pick.

While the ALX1 gene does correspond to beak sizes, due to the observed variance in the study – the correspondence is not consistent as expected from the theory of “slight successive changes.”

Regarding gene sharing, the authors report “Extensive sharing of genetic variation among populations was evident, particularly among ground and tree finches, with almost no fixed differences between species in each group.” This also is not a consistent finding as expected from Darwin’s theory of “slight successive changes.”

Since the “Phylogenetic analysis reveals important discrepancies with the phenotype-based taxonomy” and the genetic evidence failed to identify any last common ancestor or any transitional link between any of the finches, Darwin’s finches fail genetic testing.

Evolution believers should examine all the scientific evidence and look beyond the evolution rhetoric before embracing evolution carte blanche.

To answer your original question – I have the entire paper published in Nature.

Did you even read the initial article you quoted from Nature? I’m not going to go through ever point you brought up since the earlier post links to a very enlightening article however I’d like to point out what the article you quoted actually says since you seemed to have been unable to even read the abstract which states :

“Darwin’s finches, inhabiting the Galápagos archipelago and Cocos Island, constitute an iconic model for studies of speciation and adaptive evolution. Here we report the results of whole-genome re-sequencing of 120 individuals representing all of the Darwin’s finch species and two close relatives. Phylogenetic analysis reveals important discrepancies with the phenotype-based taxonomy. We find extensive evidence for interspecific gene flow throughout the radiation. Hybridization has given rise to species of mixed ancestry. A 240 kilobase haplotype encompassing the ALX1 gene that encodes a transcription factor affecting craniofacial development is strongly associated with beak shape diversity across Darwin’s finch species as well as within the medium ground finch (Geospiza fortis), a species that has undergone rapid evolution of beak shape in response to environmental changes. The ALX1 haplotype has contributed to diversification of beak shapes among the Darwin’s finches and, thereby, to an expanded utilization of food resources.”

To which you seem to think points away from the ALX1 gene having anything to do with beak shape as you state here “The ALX1 gene not only failed to consistently correspond to the size or shape of beaks” despite the fact that the article clearly states “the ALX1 gene that encodes a transcription factor affecting craniofacial development is strongly associated with beak shape diversity across Darwin’s finch species”

You then stated “Rather than finding evidence for Darwin’s “slight, successive [genetic] changes” between the finches, the team discovered gene sharing – not sequential genetic evolutionary changes.” Which is a complete misrepresentation of what is being said, I think what you mean to say is Gene Flow and not Gene sharing and Gene Flow is a well known mechanism in evolution defined as “The transfer of alleles or genes from one population to another” Which will lead to slight, successive changes in connection with the other mechanisms involved.
