Do you think the cheetah has less genetic information from its pre-bottleneck parent population, yes or no. If no, give us your definition of genetic information that leads you to reach such an amazing conclusion.
My lack of biology knowledge usually causes me to stay totally clear of discussions pertaining to genetics, but I'll take a bit of a stab at this one.
It certainly seems that the current cheetah population has less genetic diversity that that of "pre-bottleneck". I personally can't seem to see a direct correlation between "increased diversity" and "increased information". In either case, there is the information required to breed another cheetah.
Just a random, what the hey type thought.

What I said is that the cheetah has clearly lost genetic information from its pre-bottleneck parent population. For example, we know the cheetah has a deteriorated immune system and it is likely it has lost some gene segments (via crossover) and thus potential antibodies. This is clearly a loss of information, no way around it.
I know that I'm in way over my head, as far as discussing genetics, so I won't pursue this much.
To me, it seems that Fred has made a valid and interesting point in the above quoted. How the cheetah situation fits into the bigger question of organic evolution is perhaps now the question.
