Which statement (s) are true about metamorphosis:

(A) it is a highly complex genetic process

(B) it is completely governed by preexisting genetic information received by the zygote

(C) it is a form of accelerated evolution

I'd say A and B. It's not evolution because mutation doesn't occur, this change is coded into the organism's genes, every one of its kind can do it. It must be highly complex, especially since it's hard to comprehend how once a caterpillar turns itself into a liquid it can reform as a completely different-looking butterfly!
