1) Define "kind".
I think your real problem is that you want a very specific answer for something that was not given as specific.
What if I decided that I wasn't going to believe in Aristotle until I knew his shoe size and eye color?
From all the posts on here, you can see there is definitely a broad definition for "kind". Can you ever reduce it down so much that we could classify every living thing according to that system? Of course not. Not enough information is given.
So why is this so troubling? There are many things about history that we just can't know. If you can give me Julius Caesar's exact weight when he was 12 years old, I'll give you an exact definition of "kind".
