    They're separated by hundreds of millions of years of evolution, this is unbelievable to me. Seems much more likely that it would be self-impregnation, which is not all that unusual.

    It's comparable to a human impregnated by an alligator.

      Hey, there was an infamous incident of scientists accidentally producing sturgeon and paddlefish crossbreeds (this was considered to be so unlikely that the paddlefish sperm was being used as a control in the experiment they were conducting). The two species were also separated by over a hundred million years of evolution.

      It's unlikely, yes, but it's not unheard of.
