Mankind's age?

I think it's ten thousand... according to genetic population studies. I think we human may not extinct as a species because we have learnt what is called morality. Animals do not have moral law, they function by moral instinct. But for human there is moral law which deter us from operating on the survival of the fittest kind of agenda. There is also the ability to colonise other planets and solar system. Though it is not fully developed yet it seems that even nuclear bomb will not totally wipe us out. However, we may evolve... as in the sense of becoming more intelligent or grow in size etc.
