If "Caterpillar -> Cocoon -> Butterfly" evolves, why does "Butterfly -> Cocoon -> Butterfly" not?

There is the same population for both.

Are you saying metamorphosis can't become Evolution, or that Evolution doesn't want to become metamorphosis? Or something?

It's not the same principal. Metamorphosis is purely the change in insects and other such creatures from a larval stage to an adult stage.
Evolution can result in an entirely new animal all together. Like the Ambulocetus becoming a whale. That's evolution.

Metamorphosis is a process that occurs to an individual. It's a single animal that transitions from ome shape to a significantly different shape.

No, metamorphosis and evolution are completely different processes that do not apply in the same way or to the same targets.

Evolution doesn't want anything, because it is just a physical process, not a person.

Sleep on it, and get back to me: there has to be some link between metamorphosis and Evolution, that establishes why or why not, they are related?

Like selection pressures. What selection pressure would create metamorphosis but not Evolution, or Evolution but not metamorphosis?

As I said earlier, metamorphosis is a trait that some species possess, so that trait has an effect on the evolution of the species... but that does not in any way make the processes connected.

The ability to fly is also a trait possessed by butterflies and that also evolved and will have an effect on the evolution of the species... but that doesn't make flying evolution any more than metamorphosis.

Metamorphosis and evolution are not the same thing.

You've been completely uninformed this entire thread. Evolution happens BETWEEN generations. A new individual is born and it has a new set of genes that may or may not give it some advantage. If it does have an advantage it will likely pass those down to its children and they will pass those genes down to their children and the mutation will enter the population. A population is a group of individuals who are all alive at one moment. Now, sometimes a group of individuals is separated from a population. This can happen by geography, say a river or an ocean. This can happen because they move. This can be a catastrophe. A volcano erupts. Whatever the reason, suddenly you have a bunch of individuals living where they can't get back and mate with the original population. Now any changes that happen to one group don't happen to the other group. If they find each other again it's no big deal. Those changes will just reenter the other group when someone mates with someone from the other group. But... if speciation happens, a change that prevents them from breeding, then the two groups can only become more and more different over time.

Given enough time those changes will become more and more distinct. Until eventually the two populations will become so different that we would call them different species. Like chimps and humans. Which were once one population of creatures.
