But it doesn't. There's no evidence connecting the unusual genetic depletion in cheetahs (produce by bottlenecks AFTER cheetahs became a distinct species) and their lack of interfertility with other cats. You would need to take a far more detailed look at the evidence to even be able to make a case for your claim.
So again we come to the question of why you think that people ought to accept your opinion in the absence of adequate supporting evidence or reasoning.
The cause of the cheetah's inability to breed with other members of the cat family is their genetic depletion. This is one case that supports my claim.
The lack of genetic variation in species would be extremely strong evidence - probably undeniable evidence - for the Noah story where a global flood 4,000 years ago caused the deaths of all but a breeding pairs of all animals and plants.
Every living animal and plant would show the cheetah's genetic bottleneck marker. Unfortunately for you, we find no such evidence, in fact the opposite, no bottleneck exists, therefore there was no global flood. It's as simple as that.

I've answered this many times already. At the time of the Flood the genetic diversity would have been enormously greater than it is now so that the bottleneck would not have produced the high percentage of homozygosity found in the cheetah. Genetic diversity basically means high heterozygosity.
The branching into many variations (breeds or races) by the splitting off of smaller populations gradually reduces the genetic diversity in a given population over many generations, so NOW in some populations such as the cheetah, we see the condition of almost total homozygosity.
The Flood bottleneck would have brought about a reduction in the heterozygosity and an increase in homozygosity but there was still a great deal of variability left. Enough to produce everything we see today with more to spare.
Yet an overall reduction in the total heterozygosity would have occurred. An estimate of the present percentage of heterozygosity in humans is something like 7%. That's enough for a great deal of variation still, and it would have been much much higher back in the time of the Flood.
"Junk DNA" figures in this too. There should have been much less at the time of the Flood, and its accumulation was likely the result of the loss of alleles since then, the reduction in genetic diversity in other words, the reduction to greater and greater homozygosity until some genes completely lose function altogether and become junk or dead DNA. Greater homozygosity over the generations, plus more Junk DNA. I've discussed this many times before.
I've answered this many times already. At the time of the Flood the genetic diversity would have been enormously greater than it is now so that the bottleneck would not have produced the high percentage of homozygosity found in the cheetah.
And you have been shown, numerous times, that at the time of the supposed flood genetic diversity was NOT enormously greater than it is now.
You really need to stop repeating falsehoods.

Not when you say YOUR opinions are representative of ALL creationists. You make yourself out to be THE voice for YEC's. You accused me "refusing to understand creationists" because I attributed standard creationist rationale to you. Well, I didn't. You simply have different views than most creationists. Even the biggest groups.
So, again, which is it? Are CMI and AIG not true young earthers and need your corrections?

Yes, but all this division does is isolate that new "species" in its genetically reduced condition so that it has no further direction to evolve in. The whole point of the idea of speciation within the context of the theory of evolution is that it is a stepping stone to further evolution, but genetically it is either very close to the end or has reached the end of all possibility of further evolution. This is the case with the cheetah, formed by a bottleneck but still characterized by the same kind of genetic situation speciation naturally produces. It can't interbreed with other cats and it also can't evolve new variations within its own population. If you want to call it a Species unto itself you only succeed in obscuring the fact that genetically it remains part of the Cat Species or Family.
What would obscure the facts is using the word "species" to mean family, when it doesn't. No-one in the world (except you) would call a pussy-cat the same species as a tiger. This is what we have the word "family" for.
Would it kill you to speak the same language as the rest of us?
(Your fantasies about genetics are, as we know, nonsense from beginning to end, but that seems to be beside the point. Could you at least try to be wrong about one thing at a time?)
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.
In Life*, there are many hundreds of common experiences, feelings, situations and even objects which we all know and recognize, but for which no words exist. On the other hand, the world is littererd with thousands of spare words which spend their time doing nothing but loafing about on signposts pointing at places.
Our job, as wee see it, is to get these words dow off the signposts and into the mouths of babes and sucklings and so on, where they can start earning their keep in everyday conversation and make a more positive contribution to society.
