You know how spurs are supposed to be the remnants of legs from our snake's ancient lizard ancestors? How many of you agree with this? I saw a program on animal planet not too long ago that showed an x-ray of an anaconda's spurs and they actually had little bones that were described as little tiny legs. An evolutional link between lizard and snake was provided through the example of some skinks which have proportionaly short legs, and one sand swimming skink that had no legs and was for all intensive purposes...a snake. Anyway, my question is...how come on some snake species (like my dumerils) spurs are only present in males? Does it mean that the genetics for growing legs are more closely related to being male than female? Or is the whole leg theory just far-fetched? Does anybody really care anyway? ...Probably not, but I'd be interested in your thoughts if you'd care to share them.
Thanks for listening to my babble...
