rock Is there any kind of point you're trying to make here? yes , both apes and monkeys branched off 65 million years ago , thus making them seprate family |

Well, what Infinity Blade posted seems to state otherwise

...That's not even what your phylogenetic tree says.
Apes are separate from Old World monkeys. Their common ancestor was still a monkey.

Their common ancestor was still a monkey. cats and dogs share a comman ancestor , yet we dont say dogs are part of the cat family or vice versa For the third time: the last common ancestor of Old World monkeys and apes was itself a monkey. That's why apes are monkeys, because they are descended from monkeys. You don't consider dogs to be cats or vice versa because their last common ancestor wasn't either a cat or a dog. Dogs are not descended from cats, so they are not cats. |

Rock, this is not meant to be offensive or anything, but I think you should really need a basic understanding of how to understand phylogenetic trees.
When you look at the tips (AKA the species) and then zoom down, you can see that lines go down from the species and meet at certain points. These points are called nodes and they represent groups. If you are asking yourself "What species does this group include?" stop for a while and try to search for a node that would describe your group.
If you find none, your group is probably either paraphyletic or polyphyletic. Such groups are not created on the basis of any objective truth (as could be derived from evolutionary history), but on the basis of the scientists' and laypeople's convenience. If you find a node, your group is monophyletic and there is a clear answer what species it includes and what not (though we might not always know it).
