Which leads me to a really good question to all.

Could an organism (say human or dog) successfully interbreed with a member of the same species from a thousand or 6000 years ago?

.

I would say that based on ecological research and personal anecdotes, it depends on the given species' sexual behaviors. For example, mallards are well known to have sex with (or attempt to have sex with) nearly all other duck-like waterfowl, including many species of geese. In other words, mallards have very lax sexual boundaries. Green-eyed Tree Frogs, otoh, are notoriously picky about who they mate with.

We humans are definitely NOT picky about our sexual partners as species go, and I'm more than willing to lay down my net worth on the bet that we as a species would definitely mate (and produce offspring) with our ancestors from 10,000 years ago. Heck, there's evidence we interbred with Neaderthals...how picky could we really be?

Dogs...hmmm...I'm aware of some breeds that will mate with just about any other dog-like animal, so I'm willing to lay a similar bet on them as well.
