Lions and tigers are 'of a kind'...cats.
Dogs and wolves are of a kind...they're canines, aka dogs.
Man can play with the genetics of different animals and plants in many different ways; but nonetheless, a creature is what it is; they inherit their genetics from their parents.
You know that my point is overwhelmingly valid.
Canines and felines are both carnivores.
Where would you put foxes, jackals and hyenas?

You know that my point is overwhelmingly valid.If you don't stretch your point longer than that, sure. If a dog gave birth to a cat, the theory of evolution would go up in flames as well.
Speaking of genetics... If/when you have time, I can recommend reading this great post by Ichneumon (long but worth the read). While it probably won't convince you that species (in this case primates, including humans) evolve, it may give you a hint why scientists, in general, are convinced. When multiple lines of evidence points as strongly as this towards an explaination, it is hard to ignore (unless you're on the O.J. jury!).
