The first individual of a new species wouldn't find a mate (Talk.Origins)
The first individual of the new species would be very unlikely to find a mate. Hybrids are infertile, so a newly evolved individual would not be able to breed successfully with the original species. The mutation that caused that individual to be a new species would also have to occur in an individual of the opposite sex.

Talk Origins is correct on this point.
