Are humans evolved from monkeys

Its not always we think about the evolution of humans. But we sometimes do think about it. Some curious fellows would have clarified their doubt even in their childhood. The most popular answer was that humans evolved from monkeys. Even Some rational people believe that Adam and Eve were the first human beings on earth( don't forget that forbidden apple). 

But scientifically many facts related to human evolution were put forth, some of them are really convincing.

• Humans are not direct descendants of apes. 
• It is proved that both humans and apes evolved from a common descendant. 
• Chimps, gorillas, orangs and humans, all underwent millions of years of change to become who we are today. 
• About five million years ago there lived the common ancestor to humans and apes -- a dog-sized primate, who wandered the African grasslands. 

There are no fossils to prove that humans and apes share a common ancestor. There could be evolution of human beings. If the temperature of the planet raises constantly, then apparently humans may develop a physique which withstand higher temperature. The dinosaurus species was wiped out of the planet as it could not able to cope up with the environmental change. The same thing could happen to humans.   `
