they do happen...
If my tigon and liger-interested friends were right, I believe a liger is almost always bigger than either parent, and I believe he said that a tigon is almost always smaller...
I'm not sure about fertility, but I do know it does happen. Relatively rare it might be, but it does happen.
There are also documented occurences of half-cow-half-moose births, although I don't know how long they live and if they're fertile either.
To be honest, I would expect that the existence of hybrids amongst relatively similar life-forms would point to the ToE being vindicated - if they were entirely different, there should be NO hybrids at all.
If we've all come from common ancestors, sometimes perhaps (through the magic of the genetic code which we're far from fully unravelling) hybrid offspring are possible even when we think it unlikely...
still, it's fascinating.

Re: they do happen... (NOT)
Yeah, the moose-cow is a tabloid myth. Ranchers in Minnesota occasionally blame deformed calves on the horny bull moose; the two examples that got some press turn out to be endocrine problems, probably caused by a combination of recessive genes.

Well I'll have to ask my farmer-friend who keeps cows for some evidence then.
It came up in a discussion where we were talking about calves since it was that time of the year up here - they'd just had one that was born "inside out" and he'd had to put it down.
There are lots of moose where we live and the cows here are let out to roam around so there's more than enough chance for it to happen.
I don't think he was deliberately lying to me and feel it more than likely that he believed what he was saying...
