Re: Ligers and tigrons - oh my!

Peter, et al:

Aside from the obvious differences in coloration and environmental
preferences, there is at least one difference noticeable in the skulls:
If you take the skulls (minus lower jaws) of a lion and a tiger and
place them on a table, one of the skulls will easily rock back and forth
and the other will not.  (I'm not sure which is which - I think the lion
skull rocks easier).  Thom H. can correct me on this.  [This difference
is in the dentition of the animals, and the shape of the upper jaw -
sorry, no real scientific nomenclature here].

Note that I recommend that both animals are dead before you try this
experiment :-).

What makes lions and tigers distinct species, instead of just different
breeds of big cat? Is this where cladistics comes in?
