How long does evoluution take.

[Gawdzilla Sama]

Evolution is based on the reproductive cycle of the creatures experiencing said evolution, right? Bacteria with a reproductive cycle of hours would experience more evolutionary chances in a year than, say, a grey whale.

I've been under that impression, but one thing stops me from embracing that explanation.  Mutation rates are relatively constant, and not affected by rates of reproduction.  So it doesn't seem as simple ultimately as more reproduction, more mutations (not saying that is your position, but that seems a logical way to interpret the relationship between reproductive frequency and mutations.  Thinking about it now, I suspect the frequency of reproductive cycles likely simply amplifies differences in reproductive fitness, resulting in more efficient and therefore quicker selection, but I'm just spitballing).

I wasn't aware that mutation rates are relatively constant. I do know that a mutation can happen at any time. The propagation of that mutation is dependent on reproductive rates.
