Subject: homology controlled by different genes
On Richard Dawkins evolution board recently someone posted an inquiry
regarding a quote from a creationist that states

'But the real blow dealt to the evolutionist claim of the homology of
pentadactylism came from molecular biology. The assumption of "the
homology of pentadactylism," which was long maintained in evolutionist
publications, was overturned when it was realized that the limb
structures were controlled by totally different genes in different
creatures possessing this pentadactyl structure.'

I am curious about htis myself and so am asking here what is the
explanation for this?
Note I think this quote comes from Harun Yahya.

It strikes me as pure fabrication.
Limb development is controlled by Hox genes, and such genes are
extremely conservative. The same basic genes control fin development
in fish as control limb development in humans.

By "different genes" the Creationist moron surely must mean
"modified genes." The fossil record shows pentadactylism going
back at least 365,000,000 years ago, including not just five
fingers but the wrist bones, arm bones, shoulder bones, and neck
bones as well---- "pentadactylism" is just the tip of the ice
berg.

http://en.wikipedia.org/wiki/Zone_of_polarizing_activity

The finger genes of the ZPA patch that develops on "hands" in
land-dwelling and some sea-dwelling animals has not remained fixed
in any species that we know of since the Devonian, as this
Creationist nut seems to believe it should have. That is, he
assumes evolution did not happen, and then asks why differing ZPA
patch genes are different but perform the same fuctions. Amazing
how stupid Creationists can be to not even realize what they say
and write is self-contradictory.

Nested hierarcy is the explanation: pentadactylism showed up early
in the history of life on Earth, and evolution modified those
existing structures.

If Adnan Oktar were honest and not thge evil shit he is, he would
have asked why the precursors to the genes for making hands show
up in fish, sharks, and assorted finned species. Why would his
gods want us to look at the DNA and conclude hands evolved from
fins?

Yeah, it's bullshit. The genes are not "totally different:" the
cultist merely asserted they are. The "Sonic Hedgehog" gene is
observed to have changed over time, and I suppose a Phylogenetic
tree has already been mapped showing those relationships.

Any particular reason why five is preferred? Is it just an accident of
evolution or is there some geometrical or other reason five is
preferred? Why have six toed cats not taken over the world?

They can't be bothered?

Indeed, they want you to believe that, as they already telepathically
control every household they visit for food. :P

If you strap a piece of buttered toast on the back of a cat, and then
drop that cat from a fixed height, it will hover.  This is because
when you drop a piece of buttered toast, it always falls to the
ground, buttered side down.  But cats always land on their feet.

This duality creates a quantum indecision singularity, and the cat
hovers.

Because they have humans to do all the heavy lifting? And the
light lifing? And the door-opening? And the can opener twisting?

Just a guess on my part, but it appears the flippers in the first
few fish-to-amphibian species were not wide enough for the proto-
"Sonic Hedgehod" gene to make more fingers: the gene ran out of
space. Damn shame: we could use a second thumb on each hand, to
make banjo playing easier.

Acanthostega had eight digits per limb:

It's likely that settling on five was rather random, but it's hard to be
sure without knowing exactly what that selection pressure was at the
time.
