Nipples on a man have no use at all, so why, oh why??
They must have had some reason in the far past, they couldn't have been created for show. Or is it evolution? Will Male & Female become one??

In Cattle the polled (hornless) condition (P) is dominant over the horned (p) phenotype. A particular polled bull is bred to 3 cows. With cow A, which is honred, a half calf is produced; with a polled cow B a horned calf is produced; and with honred cow C a polled calf is produced. What are the genotype of the bull and the three cows, and what phenotypic ratios do you expect in the offspring of the three matings?

And what kind of traits (superior or inferior intellect, appearance, etc) will the evolved species from homo sapiens have?

This question is almost a debate I realise that. It will not in all likelihood change any minds, but may influence the minds of those who are currently suffering cognitive dissonance regarding the conflicts between Evolutionary theory and Creationist theory.

The crux of the argument to me seems to be whether 'faith' trumps 'reason' or vice versa. http://www.fstdt.com illustrated to me the gulf between those who accept the holy book of any religion as a tool for truth and those who accept scientific principle as a tool for truth.

The quote I read saying 'You honestly believe the world was created over millions of years and not six days?' just summed up the seemingly unassailable wall between the two world views, obviously the opposite could just as sincerely be said as an argument against creationism.

So, how do you KNOW which trumps which, Faith or Reason? How can we know the answer to this question? Are faith and reason totally, mutually, incompatible?
Yours hopefully,
Yuk
