Do you have any objective measure as to why?
Where do you draw a line?
Is cat a kind? Is great cat a kind?
Are wolves and coyote's the same kind? How about foxes?
If all you have is unjustifiable conviction, then you shouldn't expect to be able to convince anyone else.
Of course wolves and foxes and coyotes are the same kind.. this is basic biology.
The felines tend to be more specialised meat-eaters, have shorter faces and retractable claws. Many of them are ambush, pounce-predators, rather than runners.
The word
species is difficult to define, whether you is a creationist or not.
So why all the abuse about " kinds"?
Dogs can easily breed with one another, whether wolves, dingoes, coyotes, or domestic dogs. When dogs breed together, you get dogs; so there is a dog kind.
Creation scientists use the word baramin to refer to created kinds (Hebrew:
bara = created,
min = kind).
Generally, if two animals can produce a hybrid, then they are considered to be of the same kind.
Hybrids in the feline family include bobcats that mate with domestic cats and bobcats with lynx.
Try mating a dog and a cat...
