Here's one of my main problems with using the fossil record to prove evolution. Below are examples of some skulls. Can you identify the one that's from a different species?

Every skull in that post is a dog, including the coyote. So what's the problem?

[King Prout]

well, I'm not an osteologist, nor am I a veterinarian, but they all appear to be canines to me - not canidae, but canis familiaris.

just guessing: chihuahua, pug, some kind of retriever?, coursing hound?, a different courser?, no idea on the last one

a trained veterinary osteologist would do a much better job of identification.
