Natural selection (I assume that's what you mean when you say that the mankind came from monkey) occurs because forces of nature cause a species to adapt to something new in it's environment, giving the adapted species an added advantage over its counterparts in either reproduction or longevity (usually both, since one tends to lead to the other). Humans don't devolve back into monkeys because that effect doesn't give those "humans" a natural advantage over other humans. By the way, natural selection is not something that occurs over night, or even over the course of a few hundred years (especially in mammals)...it takes thousands of years for genetic variations to build up to a point where a new species evolves from an older, existing form, and even then the anscestral species usually doesn't immediately die out.

due to the process of heredity and evolution, there occurs sudden changes in the genes of living organisms which is called mutation.this occurs during the crossingover stage of meosis cell division, between the chromosomes. due to mutation, certain changes are observed in the upcoming generations.
thesame thing occurred in this case also. gradual genetic changes in the chromosomes of monkeys ultimately led to the evolution of human beings. genetic changes still occur in the genes of human beings also.so more & more developed forms of man can be observed.
i dont know whether the backward process is possible or not. but if such genetic changes occurs, then some day it might be possible that monkeys will be formed from man. but when that will happen , is very difficult to say.

Each difference from monkey to man is a gene in the dna tha becomes mutated for some reason.
For us to revert to a monkey it would take a lot of sincrinicity and luck. It is cause and affect, not the other way.
Their brains grew so their skullos grew. I don't know if tha would reverse.
There are people in Turkey that walk on their hands and feet and can't stand to walk.

Man does not " come from monkeys ", but shares a common ancestor with them. We are evolving and all the time. You are talking about some mutation that responds to some environmental pressure, thus being selected. Not really predictable, as the environmental selection pressure and mutational change would be total speculation.

Darwin NEVER said that man came from monkey. He said that monkeys, chimps, gorillas and other higher primates, including man, had a common ancestor. No one ever said man came from monkey. At least not anyone that understands evolution.
Evolution is not spontaneous in higher animals. It does occur rather rapidly in bacteria and virus. And no, reverse evolution has never occurred.

I totally disagree. I was created by God in His image. I did not come from a monkey or anything else. The whole evolution theory is a farce and only fools would believe such crap. Adam was perfect man, totally intelligent and civilised. And so are we and so will be until Christ comes to put an end to it all.

There is a lot common between the gene pool of man and monkey. Look at the answer from this angle.

Yes, this theory is true.
In fact, these days too this theory is applicable. Our heads are becoming larger and that too not in proportion with the rest of our body just like babies.
And, no opposite reaction can occur cause man always evolves and monkeys are obviously less evolved than humans.

man is an end product of evolution from monkey and the process of evolution is still going on to what it will lead to is a question of importance.

yes it is true because i can proove . the monkey looking man in
the past were having tail and now also human beings have the
bone of that tail.
