By "animals," I mean that one would only use the term "interbreeding" when referring to wild or domesticated animals mating. It's an inherently zoologic term, much like the word "mating."
And the first result for the second search has the title, "Can humans mate with other animals?" I rest my case.
Edit: Also, Google result tallies for individual search terms is crap evidence, just so you know. If you're going to gather evidence from the interwebs, at least try somewhat. Here's what I came up with:
Although severe inbreeding depression in humans seems to be highly uncommon and not widely known, there have been several cases of apparent forms of inbreeding depression in human populations. As with animals, this phenomenon tends to occur in isolated, rural populations that are cut off to some degree from other areas of civilization. Some notable examples include:
The Vadoma tribe of western Zimbabwe, many of whom carry the trait of having only two toes due to a small gene pool.
The Ulas family of southern Turkey have several members who walk on all fours, due to mental retardation caused by inbreeding.
Inbreeding is not interbreeding. Inbreeding is an accepted term, as in a people being "inbred." But I've had enough, you're clearly coming from a point of ignorance and are just frivolously debating now.
