Hi Jody,

Ecology seems to have abit of effect on V. albigularis across Africa, behaviors, seasons, climates, elevations, food availability, and alike all make this animal different in different parts of Africa, but their skulls are never-the-less the same in adults - so what is it that makes a species a species? The genetics (= skull morphology) or their environment? This has been a hotbed of discussion among humans since Freud and like began addressing this 70 or so years ago; and it still is - and they concluded both conditions make the animal, or human what they are....maybe this applies to zoologica too? I don't why it would not.

Cheers Jody,
markb
