Why don't any of man's recent ancestors exist today?

They all died off, due to environmental pressure and, in some cases, pressure from competing proto-humans.

Most anthropologists believe that modern humans evolved in Africa by about 100,000 years ago. They eventually spread across the world - the so-called "Out of Africa" theory.

By 20,000 years ago, the Neanderthals were extinct. But it was not known whether modern humans destroyed them, or whether their distinctive characteristics disappeared through interbreeding.




interbreeding
violent confrontations
starvation
and other forms of population decimation.
I'm sure it was very gradual.

you can also hypothesize that more distant versions of our relatives (i.e. primates) were forced to evolve in order to occupy a niche foreign to ours.

Which is why the most common relatives to humans still have many distinct features. While those who were more similar competed for a similar niche and were consequently outcompeted.

Also back in the day you had groups of animals who were usually always with each other. With the way our population is spread out now a days, wed have a hard time evolving. Its not like the packs of the early ancestors to humans, who would stay decently close knit as there wasnt a huge amount of them. So their genetics could be shared pretty reasonably.
Edit: Ha I guess I didnt actually address the question.

Ya, from what I've heard, homo erectus stayed around long after neanderthals and homo sapiens came onto the scene. I can only imagine what it must have been like to have two other hominid species around, looking so much like you and yet so different.

haha you said homo erectus

yeah, that would be bizarre.
have you read that it is believed
that many are believed to still
have the genes for, say, neanderthals
due to interbreeding thousands years ago?

So did modern primates excluding humans evolve after homo erectus had died out? I'm curious why apes and other lower primates exist today and yet species closer to modern man do not exist.

It seems apes and the like found their enviormental niche which did not conflict with the same problems that homo erectus and neadethals ran into.

No, humans and apes evolved from a common ancestor which preceded australopithecus. We became less apelike during an environmental change which turned areas of jungle into savannah, which meant that we had to leave the trees(and in response, we evolved to walking upright). The reason that homo erectus died out, as well as neanderthals later on, is because homo sapiens outcompeted them for supremacy in the same ecological niche. This took millions of years to occur, but ultimately, these other two homonid species lacked the biological advantages that homo sapiens had.

Evolution schmevolution. Does that also mean that similiar species of other animal types (birds, reptiles) "competed" with one another for ecological supremacy? And at one point there had to be quite a few neanderthal, homoerectus. Where are the fossils?

Not explicitly, but they competed for the same resources, which led to the better-adapted species filling the niche while the other died out.

Many have been discovered, while others are still in the ground. Are seriously not aware of the extensive work of paleontologists in this field?

i don't see how evolution is possible when every creature dies after a few decades of living. Like wise humans will never physically evolve into some post-humanoid.

You're kidding, right? Evolution is not something that happens to a single creature over its lifetime. It is the process by which the gene pool changes over time spans of millions of years.

They will if the environmental changes demand it(or else they will go extinct, and something else will evolve to fill the niche).

I believe we really are evolving into post humanoids.


I mean jeez, people are getting more overweight and less muscular with the further advents of technology. You could definitely also say natural selection continues to occur with more intellectual individuals outcompeting less intelligent ones.

But who knows.

OMG, evolution is not up for debate now.
Do you realize this.
Evolution is NOT a theory, it IS a FACT

But don't say "hey i heard that evolution was a theory"
NO, this is the most misunderstood piece of evolution.
The ONLY time you will hear the words"theory" and "evolution" in the same sentence is when scientists try to explain the "theory" of "HOW" evolution(fact) occurred.
The only theory in evolution now is how it occurred, NOT IF it occurred.
That is the most mistaken thing in this whole FACT!

Take for example:
what if you kept hearing the phrase " The theory of gravity"
Does that mean that gravity is a theory?
NO !
it means the theory of HOW gravity works, NOT IF it exists !
The right-wing, fundamentalist have used this theory/evolution statement to twist facts to fit their own ideas.
Once again, evolution IS FACT.
How it actually happened is whats up to theory at this present time.

uh you realize they never used "fact" because all of science is based on limited perception, and that there is always the possibility of such observations to be disproved.


You'll never ever hear ANY scientist/researcher say something like gravity or evolution is a "fact" because there's no real way of proving it. The word "theory" is as far as they can go in coining a scientific concept, no matter how many times it's been proven.
