I wonder why creationists are not citing the cheetah as an example of the Ark's cargo - it looks like it could have been the only one!
The creationists aren't citing it because they know if they do they'll get slammed.
The very existance of the "Cheetah bottleneck" is proof AGAINST the flood.
The fact that we can look at the cheetah's genetics and say - "Oh, this is different" means that there is something we are checking it against.
In other words, the only reason we know that there is a "cheetah bottleneck" is because the vast majority of species don't have the bottleneck.
If every species had the same bottleneck (as would be predicted by the Ark) then that would be our baseline and the cheetah's genetics wouldn't stand out at all.
What's more, if the creationists start hoisting the genetics flag, they quickly find themselves in big trouble since the vast vast vast majority of genetic data clearly contradicts their myth.
