what i learned today (in class of all places)
According to the rate of mutation (balh blah, kinda tuned out here) there will be no y chromosome in about 10 million years (or even earlier)
a)not saying that there will be no males (insert something about certain moles who have no male sex chromosome but still have male and females in a population)
b) if it does happen, doubt the human race will still be around by then, so nothing realy to worry about as the end of a species thing, i'm sure we do something to ourselves (read annhilate or colonise galaxy serenity style but turn into green little alien asgard style or become a trekkie etc etc etc)
On another note;
' creation took three and half billion years, genesis reduces it to one week'
