Jack: Uh... what's left to answer? I can't answer the one about the number of mutations involved in the whole process, I don't know that.
Even more than 3 mutations, to get an as simple as possible working eye that won't make the organism 'less fit' ? (and for that reason die out)
Jack: That's easier, because we still have living examples of creatures that can reproduce both sexually and asexually.
but it doesn't answer how it evolved into that.
Nobody believes that the mamal-way of reproducing could be the result of one random mutation.
Of course in theory it could be possible that any organism would reproduce by 'DNA exchange' or whatever way, while evolving sexual organs.
But that means that any organism at any given time had two kinds of reproduction methods, with one of these two being unfinished. That's against 'the survival of the fittests' unless any half-finished reproduction method would give any benefits to the organism.
Later in the process, male and female have to evolve, seperate to each other. Since nobody believes that spontaneously the male and female got one big mutation that resulted in the sexual organs we have right now.
How could this evolution process ever happen ??
Any penis would make any organism less fit if there's no vagina it could fit in. Just to state it easily.
The penis and the vagine must have evolved simultaniously.
The entire process of mamal-reproduction can't have evolved by one mutation. Hundreds of mutations are needed, the mother must have mutated to be able to bear and feed 'kids', the father must have mutated meanwhile to produce semen.
How could this EVER have evolved by accident ?
A simple step-by-step way is impossible. A simplified working mamal-reproduction system will always be either not working and for that reason make the mamal less fit, or........ well, there is no 'or' option.
Jack: The nylon bug certainly has a "new" functionality, because it didn't exist before nylon.
nylon bugs eath nylon, right ?
The bug itself did not change, the food it eats changed.
Like we humans didn't eat macdonalds hamburgers in the past.
Eating is not a new functionality. It's the same functionality, but only modified to be able to consume nylon.
Still a great example of micro evolution, that's a sure thing.
Jack: Of course, any new functionality WOULD be a "mutated" functionality. That's the point!
A new evolved organ will always be more than a mutation.
For sure if the 'old' organ still exists.

Pherhaps someone else can continue on:
- Vacuum Fluctuations....... someone dropped (must have been Zu again) don't just mention it, explain it. (briefly, if you won't spend much time)
(how can vacuum fluctuations happen if there's no vacuum ? is just a simple question you could answer as well)
