Your guy's math just doesn't work. , but all cats can evolve from a couple of species in just a few hundred years.....yeah tell me why we should accept your guy's claims?
where did you get a few hundred years, thats a false claim.
I said 6000 years. (but that technically is the era of creation),
if you talking noahs arc, we are talking about 4600 years ago.
so thats plenty of time for micro evolution to work from 16000 species.
all they would need is founding parents taken from separate areas, in order to increase their diversity.
"many birds transplanted within Australia have been started by single pairs of innoculi (see appendix 1 in Newsome and Noble 1986)"
"The introduce Laysan Finch on one of the Hawaiian Islands may have descended from a single pair of birds (Conant 1988, p256; Pimm 1988, pp. 290-291)
"Likewise, a population of American Gray Squirrel, started by one pair of founders, fourishes in Victoria, Australia (deVos et al, 1956, p.179)
"the rock wallaby introduced to Hawaii (Tomich 1986,p17.)"
racoons introduced to the Bahamas (Sherman 1954, p. 126)
"elk introduced to california" (McCullogh 1978, p. 174)
"Hence, a founder population of two lizards collected from different local populations would display more genetic variation for all diversity measures withe the possible exception of N than a sample of 50 lizards from a single local population (Templeton 1994, p 62)
