We hear a lot about mass extinctions, and invasive species. But what about new species emerging? If the premises of evolution and mankind's changes being significant are both true, then when can we expect to see the new species emerge?

Thanks.

In order for evolution to begin (through reproduction) isn't it necessary for the complex reproduction system to already be in place? How are females and males so different, yet work together so well to reproduce? I understand how evolution can account for a change in a species, but I don't get how it can account for the origin of the sexes.
