When a new, better, more capable of surviving organism (or maybe just a different, but just as viable organism) evolves out of an existing organism, there are a few options for the old organism.
1. They both are able to live together and flourish along separate evolutionary paths (apes), both often evolving further and maybe later facing options 2 or 3.
2. The existing organism must move to another locale to avoid being phased out by the success of the new one (I don't have a good example).
3. The existing organism is no match for the new one and loses out on resources to the point of becoming extinct (Neanderthals v. humans).
I think it is the great intellect of the evolved homo species that forced the old ones out, though there is a group of people in the Indonesian islands who they believe might be descendants of a slightly different homo line that evolved in seclusion on their island. So, other homo species might still exist after all.

For the same reason that many species no longer exist.Extinction.The only difference is that some species, like many fish, birds, reptiles and man, evolved and as we evolved our less evolved cousins went extinct.
For your added details:
Take two tribes of ancient man.Each tribe has about a hundred members.Ten members from each tribe mate with ten members of the other tribe.Their offspring are born a little different.Not much.But a little.They can stand up a little more straight and don't have as much hair.Then they have children.The change increases.Over the course of time they evolve.
Is your great great great grand mother alive?How can you be alive if she isn't?That about sums your reasoning.Just because we are here today doesn't mean that a long time ago we didn't have ancestors.And our ancestors changed over time.At one time we were shorter.At one time we had shorter expected life spans.Does knowing that mean that our ancestors didn't exist because we are not like them?

Because, like you, the cave men had a bad habit of setting themselves on fire. I saw one guy do this to himself once and it's just not pretty, but we humans developed something called hospitals, so the nitwit survives to this day despite his apparent eagerness to win a Darwin Award. I can see how people don't understand the concept of natural selection when we live in a society that works hard to keep the suicidally stupid alive.
Of course, you could be talking about how cave men have changed since, technically speaking, cave men were homo sapiens sapiens - US! What changed? Well, now we have electric shavers and computers. We're still pretty ugly in comparison to most birds though.
You *could* also be refering to "Peking Man" or homo sapiens neanderthalensis, which were two off-shoots of the same genus. And I suppose neanderthals having a larger cranium makes one wonder why they didn't outsmart our cave man ancestors. Well, maybe they were too smart for their own good? Supposedly there's evidence that points to a declining reproduction rate. Either cave men were better at fighting them despite being smaller or there was sufficient ability to crossbreed with cave man being the dominant phenotype. That later theory is kind of Eurocentric though since neanderthals were limited to Europe and Europeans may feel a need to inflate their heads with dreams of having greater cranial capacity than others...
Anyhow, my theory is this: Neanderthals were so smart that they invented religion early and all decided to convert to Quakerism, which meant that they all thought sex was too sinful. So basically they out-thought their own procreation and ceased to exist. Maybe we will all meet them as happy Quakers in the spirit world?

Look. Isolated populations are supposed to evolve separately. So evolutionists believe that if it had happened that all the monkeys in the world were in the same place and shared genes with each other, THEN there would be no monkeys today. But if one group was in, say, Africa while another was in, say, Asia, then one of them might not get the memo. Dig?

Perhaps it would help you to look up what the word "evolve" actually means? I'll help you out...a process of continuous change from a lower, simpler, or worse to a higher, more complex, or better state. Once you evolve, you don't go back.
I hope this helps.

Why aren't there any other extinct species in the world? Oh, yeah, because they're extinct!

The Earth exploded once before wiping out life entirely and God built it back up.
Now here's the Philosophical question? Why build something only to destroy it?
The solution to that is God doesn't believe in ending one path to Twilights.

If you're still using the word monkey by now, you've been put out already and are just feeling the burn from talking to someone uneducated.

We share a common ancestor? Prove that! You can't do it. There is evolution happening but that is not likely to be how it works.

OK, you might want to put out this "fire"--it's distracting you from asking a sensible question. Species die out because they are unable to adapt to a changing world.
