Yes, the primate order began in Africa, and so did its two most distinguished families, the hominids and the apes.
I believe in what anthropologists call "the ancient candelabra theory." I dispute the Recent Out-of-Africa theory that some claim is supported by mtDNA studies.
In the ancient candelabra theory, Homo erectus dispersed from Africa into Europe and Asia about a million years ago. The hominid family wasn't particularly specialized in either form or behavior, excepting the primate specialization in large brains.
Given the biological momentum, it was reasonable that the easiest adaptation to new environments to be made were further extensions of the existing specialization. In other words, Homo erectus dispersed from Africa, became racianated due to geographical isolation, yet nonetheless there was a certain amount of parallel evolution toward higher intelligence in most of the dispersed hominid groups.
Hominids that wandered toward the north had an accelerated evolution of the brain. Their tribes were culled by cold weather in favor of large brains, since the brain is an organ vulnerable to freezing in cold weather, while size is a defense against being frozen.
Once the additional brain mass was there, natural selection was quick to put it to use. That's why the extant hominid races whose ancestors left Africa are much better developed (more evolved) in the brain than those whose ancestors remained behind.
Although there's no question about where the hominid family originated (Africa), there is some dispute about when the hominids emerged from there. Those who rely on mtDNA studies say that the dispersal happened about 135,000 years ago, whereas much other evidence (fossils and artifacts) indicates a much earlier emergence: about 1 million years ago. The former theory is the Recent Out-of-Africa theory, whereas the latter theory is known as the Ancient Candelabra theory. It is the latter that I believe is true.

Humans evolved from a common ancestor millions of years ago. The oldest early human fossils were discovered in Africa - much of human evolution happened on that continent. The fossil record indicates all this.

. The fossil evidence and evidence from DNA studies indicate that the human race originated in Africa.
. The oldest fossils whose characteristics barely separate them from the pongid lineage and place them in the human lineage have all been found only in Africa. Fossils of human lineage which have been found outside of Africa include only those which, though more primitive than homo sapiens, are not much like apes at all. and they are found both in Africa and in Europe/Asia.
. DNA studies show that there is more variation in the DNA of different groups in Africa than there is among all of the groups in the rest of the world. This is most likely due to there having been humans in Africa, picking uo DNA variations with time, much longer than humans have been in the rest of the world.

Most of the anthropology throws light that equatorial parts on earth were the
first habitats of the human race because most of them were full of vegetation and rivers. One cannot say exclusively Africa only but also South Asia especially South India, Present day Srilanka The life of mammals incepted
from equatorial side from south pole upwards. The HUMANS also first evolved from here. The second theory is that SOUTH ASIA comprising Present INDIA, AFRICA , were the first parts of FIERY BALL to cool down especially the parts of PRESENT EARTH (From Equatorial towards South Pole). Therefore we have big oceans over here.Naturally life began evolving
over here and hence FIRST HUMAN RACE evolved here.

I believe it certainly could have and evidence would seem to point in that direction. Wouldn't north eastern Africa be where the Garden of Eden would have been?

Mitochondrial and Y-chromosome research indicate not one, but multiple migrations of early humans and humanoids out of Africa. Migrations of Cro Magnons into Europe about 40,000 years ago coincided with the gradual decline and extinction of the Neanderthals, whose ancestors had themselves migrated out of Africa hundreds of thousands of years earlier. Some hominoids migrated out of Africa millions of years before humans did, but were unable to adapt to their new environment and died out. Some researchers hold open the possibility that humans may have come into contact with the last vestiges of Homo erectus in Southeast Asia just before H. erectus went extinct. If this contact did occur, it must have been a stunning experience, on par with early humans coming into contact with "Flores Man" (possibly a new species, tentatively named Homo floresiensis) in Indonesia circa 40,000 years ago and coexisting until only 12,000 years ago.

i think of even a number of the main racist are coming around by way of no longer being waiting to project the technology in it. Now their emotions are yet another component b/c you're saying that a team you hate is actual your mom; so it robs them of feeling that they are unique and extra advantageous. i might prefer to stay 50 extra years to work out what the subsequent prejudicial argument would be approximately.

It does not matter what I believe. A suite of credible evidence points unerringly in that direction. You want to believe otherwise? Then do so, but all intelligent and educated people will know you as deluded.

So far all evidence support this theory,until someone come up with contridicting evidence; I am supporting the Africa theory!

To be concise and make two points. Yes!
To be accurate and follow what science has shown...... yes
To be a booger and plant my own theory... not entirely because extraterrestrial beings also added to our existence. I'm just going by the written records and paintings that show ET with us in many countries to include Africa and America and Asia and, well, you get the message.
