Then, we will try and estimate how long each change ought to take on average.
Isn't that a bit like trying to calculate the average mass of every organism on earth? What would that "average" even mean?

If you wanted to argue that there hasn't been enough geological time for evolution to occur, you'd need to know the maximum speed of evolution. What's the point of knowing the "average"?

In nature we see certainly do see reuse of designs.
But what we don't see is retro-fitting of the improved designs across the board. Once the better octopus eye was invented, why wouldn't a designer rewrite the DNA of mammals to use it? After fancy electric headlights were designed for cars, we don't still see aircraft flying around with candles.

There just seems to be a siege mentality where people would rather not acknowledge problems with scientific inquiry.
I think it has more to do with wanting to get on with the inquiry instead of obsessing about how the inquiry is done. It's like going in vacation instead of incessantly planning the perfect vacation.
