does man can again evolve into an ape

Again. Humans did not evolve from apes. We share a common ancestor with them. You have some serious misconceptions about evolution. If what you intend to ask was : Could humanity change into another specie , over a long periodo of time, that resembled todays apes, the answer is probably no. Why? Because our inteligence is a tremendous evolutionary advantage and I don't see what kind of environmental pressure could cause such change, hence the probably no.

it wud be devolve not evolve....and i seriously think that humans have no idea as to what HE has planned for us!!!!!!!1
