A chromosome loss would be almost impossible to survive unless it was a duplicate of another chromosome.
Hmm... not sure about that. Humans have 46 chromosomes, but we almost certainly evolved from animals with 48 (given that Gorillas, Chimps and Orangs all have 48).
I'm not sure that 'loss' in this case is really what happened.
Yeah, see you point; I did not word that very well. What I think I meant to say was that sabre teeth come and go over time, rather than evolution having to 'go backwards'.

But remember, we didn't actually lose a chromosome pair. Instead, we have 46 (not 48) because of a fusion event, not a loss.

That's not a loss, that's a fusion.
Chromosome 2. An article so profound in its intellectual brilliance that I can only say ... I wrote it.
