In other words, there are only five sets of information that each describe expression of a unique digit.<br /><br />Polydactyly is common, but you will ALWAYS find that the extra digit is a copy of one of the other five, never unique.<br /><br />Pentadactyly is neither adaptive nor contingent. Natural selection actually had nothing to with it. The 5-only contraint on the Hox-4 genes were in place long before terrestrial vertebrates evolved, and long before nature moulded fins into limbs.<br /><br />Pentadactyly isn't a mystery, but the ancient five-way Hox gene contraint that caused it eons afterwards, is.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6868618319990879375.post-58369265862094993562007-05-24T14:12:00.000+00:002007-05-24T14:12:00.000+00:00WOW!You'll be explaining about the congenital abno...WOW!<BR/>You'll be explaining about the congenital abnormalities of Springfield next....why do the evolutionary characotrs have 3 fingers? a local nuclear power station or just easier to illistrate!<BR/><BR/>I (in my simple minded capacity), guessed the extra fingers where 1/2 evolved fingers, not yet made there evolutionary way from fins.<BR/><BR/>I think this site is toooooo clever for me!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6868618319990879375.post-32859254305674527302007-05-20T22:23:00.000+00:002007-05-20T22:23:00.000+00:00I'm back and was searching about the ostrich peopl...I'm back and was searching about the ostrich people, and found it on Wikipedia. And in my search for photos, I also found this site with a page on <A HREF="http://www.messybeast.com/poly-cats2.htm" REL="nofollow">polydactyl cats</A>. I remember my own cat having an extra useless "thumb." Useless because they were like dead and was just hanging there. But I think that cat was a real genetic disorder in many ways, since one paw had an extra "thumb." The other paw had two nails on one digit. The cat was pure white that his eyes were very noticeable. One was blue and the other was green.<BR/><BR/>But just a background on it... when it was still a kitten, it was a stray kitten that took a ride in our car, that seemed to climb under the car and ended it's way near an area near the car battery and was securely there until we got home from a bowling trip that was just about 1 kilometer away. He was kitten although he was big enough not to depend on his mother. For me he was the best cat I had. I had cats since 1978 up to today.<BR/><BR/>When ever we go back to the bowling alley we kept going to... I noticed by the side of the building, is a big trash can and some trash dumps near it where several stay cats go to. I am not surprised if my cat's mother was probably one of them feeding on all these trash while she was pregnant.<BR/><BR/>WOW! Is this the longest comment I made in history? Hahaha. This is good enough as a blog post. Haha.

I didn't think that getting some more would be much of an issue, and may be the character would quickly get fixed, if advantageous.<BR/><BR/>So, we can't have more than five 'cause otherwise other parts of our bodies would not develop correctly.
