Evolutionists.  How is human head hair evidence of evolution?

There is no such thing as an evolutionist, not even bothering to read the question past the word evolutionist.

So, you discovered that different characteristics exist among different species, and you think that disproves biological evolution, when in fact that is exactly what biological evolution is all about.

Well! If you don't want hair, cut it off!

You don't seem to know what evolution is and how it works. Perhaps you should learn before you mention it again. That way you won't embarrass yourself like you just did.

Not every trait has a marked evolutionary advantage. 

There is no such thing as an "evolutionist." 

How staggeringly ignorant is it to think that some claim about hair, all by itself, is somehow going to challenge the bedrock foundation of modern biology?

Last week you tried to do this over chins.  This week it's hair.  Which one will you "grace" us with next time?  Earlobes? Cowlicks?  Boogers?  Zits?

Yep you christians are dumber than a box of hammers.   Animal hair falls out after x length and y time  

Have you noticed that your pubes do not need to be cut.  They fall out.  But you many have not reached puberty yet.;

IT IS NOT.....GOD MADE ALL LIFE BY SPEAKING IN BEGINNING AND THE REST OF US CAME THROUGH SEX.

Actually, I can explain why women don't have beards from an evolutionary standpoint. Traditionally, women have been the ones to remain home with the children. Therefore, successful mothers have had higher pitched voices and less facial hair so that their children would better relate to them.
