Re: Another FAQ




George,
In all fairness, it depends on who is looking and how closely. If one didn't know better, one might well think the Tasmanian wolf was a member of Carnivora. A closer look at the teeth, mode of reproduction, etc., would quickly expose this convergence of general body form and way of life. But to the untrained eye, a Tasmanian wolf could easily look more like a wolf than a French poodle.
The same could be said for convergences among dinosaurs. It depends on who is doing the looking and how much they know about the details of anatomy.
-Cheers, Ken Kinman

IDENTICAL?? Give me a break!
