Yeah, makes a lot of sense that some of the monkies didn't make it.
rolleyes What are you talking about? That some of the monkeys (which is incorrect because we share a common ancestor with apes, and are, in fact, still apes) didn't evolve? It makes perfect sense.
The problem with saying that if we had come from monkeys, they wouldn't be around is that evolution doesn't just magically change an entire species. Evolution works within populations. It's called speciation.
Here's a nice, hypothetical situation that will hopefully allow you to better understand what you're talking about.
You have a population of 100 animals (usually populations are much larger, but 100 will work for this example). 99 of these we will call 'A,' and the other one is 'B,' because it has a genotype that codes for a phenotype that gives it an advantage over A. Let's say that something happens that separates this population into two different populations of 50. Population A (composed entirely of As), and population B (with B and 49 As). B will survive to reproduce more than the As in its population, and it's genetic code will be proliferated more and more, until all of the organisms share the part of its genome that gave it an advantage.
Along with all of the other changes bound to happen in population B, this will cause this population to be composed of what I will call X. The changes bound to happen in population A will lead to this population being composed of what I will call Y. X, as a result of this evolution, is much more different from A than B was, and even more so from Y.
Because of this, humans (which could be 'X'), and other apes (which we actually evolved from, and could be 'Y') both exist.
