The problem with that is, theres no thousadns of years gap between the two types, one essentially morphs into the other.
NO
how much do you know about evolution...
heck dolphins lived on land once
and we came from lancelets
do you know what lancelets are? there fish...
yet we don't have gills...
I'm just trying to say anything can happen in evolution
it doesn't exactly mean the origional species had the attributes of all the sub-species and became specialized...
a lot of insects evolved from anthropods... that lived in the ocean. now look they die in a glass of water.
EDIT: remember what somebody said (it was a couple of pages ago) they respirate through their leaves at the ends of their stems once the poison reaches the leaf and diffuses into all of their cells they die... adumbrodeus stressed on the fact that this is potent stuff
Also, white pikmin can change back to normals with that spotted flower.
This means that there shouldnt be any real fundamental chemestry change between the two other than size, and the fact white shave poison glands.
If the two are interchangeable like this, the poison shouldnt be fundamentally dangerous to a Pikmin.
WHo knows, the poisons you see int the environment could just be different...
(as for white's special immunity to it, thats just game mechanics to solve puzzles)
