Re: For those that don\'t believe in evolution - why do men have nipples?
[ QUOTE ]
All human embryos begin as female. Later stages of development release hormones that effectively change the gender of the embryo from female to male. The nipples have already been formed by that time. I believe in evolution, but I don't understand how your analogy proves your point. [/ QUOTE ] "Begin as female" might be a little misleading, but yeah. If certain genes (SRY for example) are turned on certain changes occur that lead to masculinization, if they remain off certain changes occur which lead to feminization. But changes still (obviously) must occur for anything resembling a normal sexual development. They both start out androgenous is probably more accurate. |
