Ow boy....
Cats, tigers, lions, ... = felines.
Humans, chimps, gorilla's,... = primates
The ancestor of humans and chimps was a primate.
This primate produced more primates: humans and chimps.
The ancestor cats, tigers, etc was a feline.
This feline produced more felines: cats, tigers, lions,...
Felines, canines, primates,... = mammals.
The ancestor of felines, primates, etc was a mammal.
This mammal produced more mammals: felines, primates, canines, etc
Reptiles, amphibians, mammals = vertebrates.
The ancestor of reptiles, amphibians, mammals was a vertebrate.
This vertebrate produced more vertebrates: reptiles, amphibians, mammals, etc
Once more: speciation is a vertical process.
Felines do not produce canines.
Felines produce more felines.
Primates do not produce felines.
Primtes produce more primates.
Mammals produce more mammals.
Vertebrates produce more vertebrates.
At no point in our evolutionary history did one "type" become another "type", nore is it required.
So this seems to be yet another case of a creationist trying to argue against a theory that he does not understand.
I'll just leave this diagram here and let you ponder the implications:
