I make myself out to be the voice for YECs? Huh? I believe I simply pointed out recently that I AM a YEC and share their basic point of view on the Young Earth, as opposed to the other Creationists who post here, who aren't YECs; hardly a claim to "be the voice of" YECs, and hardly implying anything that would require me to agree with absolutely every point made by a YEC ministry.
It's of course hard to produce evidence for this but logically it hangs on the fact that the production of varieties breeds or races involves the splitting of populations into smaller populations which remixes the genes/alleles and of necessity reduces the proportions of some (while increasing the proportions of others), so that overall over time there is an increasing reduction in genetic diversity down the generations as alleles that don't contribute to the new breed eventually drop out altogether. This can happen enough to kill some genes altogether (junk DNA). You get new breeds or varieties or races from new populations that have an overall reduced genetic diversity from the parent populations. Tracing this back extrapolates to greater diversity the further back you go.
The Linnaean classification was just one man's ponderings, it is not based on genetics so it is open to question, and to my mind logic requires that cats be cats.
It is not really important to my point anyway, Tangle. The same processes I'm talking about apply in either case. Reduction of diversity occurs as breeds develop whether big cats and little cats are of the same species or not. That's just a red herring.
There s no evidence on your side of this either, it's all conjecture, and I do have logic on my side. Again if it could be tested genetically as I've described then we'd know if my prediction is correct or not.
It seems to me that when new species are formed, they usually contain more genetic material and not less.
They are formed from a split off a larger population. The smaller population cannot possibly have more genetic material than the larger. It takes the reduction or loss of alleles for the former characteristics for the allleles for the new characteristics to increase, and often the former disappear from the population altogether if the population is appreciably smaller than the original.
