One quick question Peg, how do you know that humans and chimps can't hybridize? What experiments have been done? How about humans and orangutans?

Do you know that human sperm has been tested and does penetrate a gibbon egg?
Sperm/egg interaction: the specificity of human spermatozoa - PubMed
Gibbons are the apes furthest from humans on an evolutionary scale if I remember correctly.

Re: Kind (Wolves)
I question your specific claim: (bolding mine)
...But if you leave them alone in the wild insemination will never happen ...
Without mankind's intervention there would be no wolf dog....
Wolf Dog Hybrids in the Wild
Rare but it does happen
If fact, wolf and dog are not the only canid hybrids found in the wild.
Other Canid Hybrids
It seems that some domestic dog breeds are inching towards non-interfertility.
Are all "dogs" interfertile?

Re: Kind (Wolves)
you stated that it will never happen in the wild:
...But if you leave them alone in the wild insemination will never happen ...
Without mankind's intervention there would be no wolf dog....
Just showing that yes it does occur in the wild, and not just wolves and dogs.
You don't call that human intrvention?
By necessity, it would have to happen where there is a population of dogs, and populations of dogs generally happen near human habitation. No I do NOT call this human "intervention".
