Sounds preposterous? Think about it.
If you've seen pokemon or played the card game long enough, you'll see that the pokemon move up through points and levels (similiar to XP and user levels here on E2).
If the pokemon reach a certain level, they evolve. For example, Pikachu evolves with a lot of bright light and in seconds into Raichu. Most pokemon have 3 evolutionary states, some have 2, or only 1. Most aficionados of the series know very well who evolves into what and when. Check your pokedex.
I guess the point of the nodeshell title that I'm filling in is that Pokemon evolution is not real. Real evolution takes thousands upon thousands of years, and natural selection to take its course, as told by Charles Darwin. What Pokemon calls 'evolution' is really 'metamorphosis' but the Game Boy display is only 20 characters wide. Therefore any scientific realism is discarded, and in a few years, a few of the less savvy students will be confused in high school Biology.
Learning something fantasy and calling it the same name as the boring, real thing, probably isn't a good idea. Imagine primary school science class:
Teacher: Now, evolution takes place over thousands of years-
Student: But that's not what happened in Evolution the movie! Or in Pokemon!
Ah, this will confuse the younger kids. A single organism doesn't evolve during its lifecycle, let alone the two or three times you see squirtle do it on TV.

Note to The Alchemist: Evolution is defined as a change in a species from generation to generation.
