This is actually a common misconception.
The word "hominid" refers to members of the family of humans, Hominidae, which consists of all species on our side of the last common ancestor of humans and living apes. Hominids are included in the superfamily of all apes, the Hominoidea, the members of which are called hominoids. Although the hominid fossil record is far from complete, and the evidence is often fragmentary, there is enough to give a good outline of the evolutionary history of humans.
The time of the split between humans and living apes used to be thought to have occurred 15 to 20 million years ago, or even up to 30 or 40 million years ago. Some apes occurring within that time period, such as Ramapithecus, used to be considered as hominids, and possible ancestors of humans. Later fossil finds indicated that Ramapithecus was more closely related to the orang-utan, and new biochemical evidence indicated that the last common ancestor of hominids and apes occurred between 5 and 10 million years ago, and probably in the lower end of that range (Lewin 1987). Ramapithecus therefore is no longer considered a hominid.
Whilst modern Human and Great Apes share a common ancestor, we are of a completely different species.
The ancestor of the Apes took a slightly different evolutionary step to what became us.
Perhaps the genes or DNA precluded the development of sentience or even of bone restructuring which allowed us to begin to walk upright.
The Apes and Monkeys have evolved over a similar period to ourselves but the changes were still animalistic and have been quite slight except for size and the development of the 'family group'. Behavior changed but the physical aspects didn't.
For 'us', the physical shapes as well as the form of our brain drastically altered over the course of a few million years. This is an incredibly fast rate of change which some theorists have concluded, that radiation and 'mutants' may have contributed to the gene pool with viable plasm.
The debate still rages on that score though!

RV 1988 you are a complete idiot. Now to Answer your question on how come apes are still here. We all come from a common ancestor. Basically through natural selection and reproductive isolation, a new species can form. Natural selections is basically that only those best suited for their environment will survive and reproduce offspring with their traits. Those with traits that do not help them will die because they are not suited for their environment and thus will die off=not able to pass on those traits to offspring. Overtime you will only see the animal with the favorable traits. During a long period of time as this happens, the species can change so much that it evolves or becomes an entirely new species. Basically the answer to your question would be that we and Chimpanzee's may be the closest related but we are so different because we have been evolving separately from each other for about 30 million years.

A long time ago we had a common ancestor, natural selection took monkeys 1 way and people the other.
We still share around 98% of our DNA with them.
You could ask the same question about birds..... How come an eagle and a crow exist at the same time? Same answer

We didn't evolve from present monkeys and apes. We all shared a common ancestor and as a result evolution took us all in a different direction

im not sure
they may have evolved from colonies of apes moving to richer grounds and evolving along the way leaving the other apes in the same environment not needing to evolve

There are a lot of different species of monkeys. And BTW some of us haven't evolved. I love bananas.

We did not evolve from apes, we are different creatures. We all have the same creator, God! Man was created in God's image, and that is why we are set apart from all the other animals.

If you came from your grandparents, why are your cousins still here?
