Nut we have a winner in Brian1009 at #16, quoted here in part:
according to Wikipedia on interspecific hybrid naming conventions:
Hybrids are often named by the portmanteau method, combining the names of the two parent species. For example, a zeedonk is a cross between a zebra and a donkey. Since the traits of hybrid offspring often vary depending on which species was mother and which was father, it is traditional to use the father’s species as the first half of the portmanteau. For example, a liger is a cross between a male lion and a female tiger, while a tiglon is a cross between a male tiger and a female lion.
Therefore, to properly name this hybrid, we’d need to come up with a portmanteau that combines the first part of the male parent’s name (pig) and the second part of the female parent’s name (chimp).
In following conventional interspecific hybrid naming conventions, then, we humans can trace our ancestry all the way back to the very first pimp.
We will leave the official zoological nomenclature to Darwin’s nomenklatura. To the rest of us it’s just this: If the theory is true, great-great grandaddy was a, er, pump or something, we’re not sure… 😉
Seriously, Brian1009 needs to be in touch with Denyse O’Leary, firstname.lastname@example.org, to provide an address to which the prize, the DVD of Flight: The genius of birds, may be mailed.
