@Leadfoot,
how does any of that vaguely imply design?. Im really curious how we (or you) get to that conclusion.

You do have a learned " bifurcate vagueness" about your statements. I always thought that it was so you could try to not get cornered, and thus blame the other guy for dimness at its lack of understanding .
If snarling rats eat all the kiwis does that not comply with your superpredator concept? Think of it another way. Many vegetarian animals are limited into the range in which their main host plants live , and as these plants succumb to some outside edaphic force (or climatic), so does the animal. Look at all the insects in which "host plants" are being reduced in numbers .
"Superfoxes" derived from Eocene placental pre canids, (I wonder how many genera there were in total since the Eocene till today).
Something like Andrewsarkis was a carnivore that seemingly separated the hyenas from canids etx etc. Did any of them "eat themselves out of existance"? We do know that several of the "met eting toothed" precanids were more or less initially unfit for the coming Savannah conditions because of the fore and aft "locking" of their hip bones. While prey animals evolved from a common ancestor ( evolving a hip and foot structure as well as a surfeit of mitochondria thus causing an arrival of the fittest for open savannah). True Canids, like wolves ,foxes, and even bears and cats, waited till the Oligocene to explode in species, perhaps as an adaptation to the newer environments which brought out the megatheria plant eaters.
Youd have to follow a single species at a time to answer your question. Hoover, I feel that from what we know about what early man did to mastodons and imperial elephants and moas, we can extrapolate with a degree of certainty that the same things happened with other species of meatatarians and plant eaters.
