Evolutionists, where, geographically, did man evolve?

I'm not too familiar with either. The polycentric theory of social evolution is discussed by Herbert Spencer, and the polycentric theory of biological evolution by Franz Weidenreich. The one from Franz proposes a split from Homo erectus and possible interbreeding afterwards. Not sure if this could explain or take into account such interbreeding as between Homo sapiens sapiens and Homo sapiens neanderthalensis.
Just looked it up and basically the concept is that we inter-bred with the different other hominids that existed to give us more expanded roots. Though homo-sapiens themselves actually developed in Africa. However we have bits of other hominids in our blood. Neanderthal being the most prominent.

It isn't anywhere near as widely accepted as the OOA model but its still a legitimate theory.

But didn't Homo sapiens evolved from Homo erectus which existed in several parts of the earth.

Yes. But we didn't independently evolve all over the world from homo erectus. One specific and isolated group of homo erectus developed into what we now call homo sapiens.

Homo Erectus lived on earth for 2 millions years, what had happened that made the Homo erectus in Africa to be evolved to Sapiens whereas the rest all over the world to went extinct.

Unfortunately, as humans continued to evolve, they made better and better weapons, plus were able to better compete for available resources than other humans who didn't culturally advance as much. IOW, we learned to kill our fellow humans much more efficiently, so maybe my use of the word "advance" should be more tempered

During that time frame, not only did our brain size increase, but probably its efficiency on tool making and learning to outmaneuver both prey and other humans increased as well. This is the general pattern we see, although it's not always clear what the specifics were. The animals H.e. was able to kill got larger in the latter part of their existence, but they must have proven no match for the emerging Neanderthals and Homo sapiens that gradually replaced them.

Why the Homo sapiens need to kill the Homo erectus ? why they didn't do the same to Monkeys and chimps ?
Were the Homo sapiens united and organized to kill the Homo erectus all over the world ?

"Man" is still evolving. Where man evolved from geographically all depends on from what point a person consider man to be man. Is it at the point where we label out species Homo or specifically at Homo sapiens archaic or...? Or perhaps we can start with Australopithecus? Don't know. Which "man" are we talking about?

Monkeys and apes have their own niche, but our ancestors seemed to be better adjusted to the savannas where food, but also risks, were more abundant. Also, please realize that we're talking about maybe tens of thousands of years whereas this transition appears to have taken place. Even though we may not know the details, the results are obvious as no H.e. now exists.

"Man" is a continually evolving entity. We became biologically distinct from other primate species in North and Central Africa. We have settled all of the continents, and on each save Antarctica there originated unique genetic material that has entered our common gene pool.

But that doesn't answer the question of the reason that Homo sapiens eradicated Homo erectus from our world.

Actually I did answer it. Generally speaking, humans have historically fought over control of resources, and we well know there was conflict between different groups. H.s. was generally better equipped to both handle these conflicts and also to better compete over food and water. IOW, H.e. was "in the way", much like the Amerindians were "in the way" of the Europeans who came here to the Americas, whereas an estimated somewhere between 40-80 million perished directly or indirectly at their hands.

So, do you have your own theory on this? If so, I'd be interested even though I'm gonna be outta here shortly.

Population were very few before 100000 years ago and i don't think fighting for food is a good reason to eradicate Homo erectus in every part of this world.
