<!--QuoteBegin-->QUOTE<!--QuoteEBegin-->- What prevents homo sapiens from mating with monkeys for example ?

The classical defenition of a species is...
a group of organisms that have a unique set of characteristics (like body shape and behavior) that distinguishes them from other organisms. If they reproduce, individuals within the same species can produce fertile offspring.
They can mate...but there is no use...they cannot produce offsprings that can reproduce. so, they die out. Geographical isolation is a key factor in origin of new species.

I doubt that. Our ancestors will be a different species by then. May be some primitive form of hominid.
Can some one give a reference?
