I don't know. Pangea was a thing, so perhaps everyone was just scattered on this same continent?

yeah if your talking about evolution, there was some scriptures of roman scholars who said the same thing that even todays science are actually agreeing that people was originated to a single man from africa. but for me i bilieve that people started from asia, asians evolve to brown, to black into white because of the environment and some people with genes that can produce white skin and it all depends on the oxygen the harder you breath the more you could adapt to the environment, thats why black have huge dingdong because their ancestors probably lived to some higher grounds a long long time ago ??????

ahh reminds me of that song "every color, every hue.... its represented by me and you"

But according to a study I posted earlier, The tools found in Australia were far more primitive than the ones found in Africa.

That can only mean two things... Either the africans sailed to Australia and forgot how they made their tools, or the humans came out of Australia and developed.



Also dna suggests life starting in two different spots

“the finding that the Europeoid haplogroups did not descend from “African” haplogroups A or B is supported by the fact that bearers of the Europeoid, as well as all non-African groups do not carry either SNI’s M91, P97, M31, P82, M23, M114, P262 …”

There are 11 more entries in this list of non-starters, all missing from both Europeoids and “all non-African groups,” which obviously includes the Original Australians. With the Original people exhibiting an intense clustering into two groups, haplogroups not present in any African genes and an absence of dozens of African genetic markers, it is very difficult nigh on impossible to sustain any link between Africa and Australia."

I see. I didn't see your link but I just read a couple articles on the Australia situation and you're right. Mitochondrial DNA suggests the earliest life for that was in Australia about 400,000 years ago.

As far as the European halogroup, it said R1b is the most common halogroup in Western Europe, and as far as it's origins it said this:

Spoiler

The origins of R1b are not entirely clear to this day. Some of the oldest forms of R1b are found in the Near East and around the Caucasus.
Haplogroup R1* and R2* might have originated in southern Central Asia (between the Caspian and the Hindu Kush). A branch of R1 would have
developed into R1b* then R1b1* in the northern part of the Middle East during the Ice Age. It presumptively moved to northern Anatolia and
across the Caucasus during the early Neolithic, where it became R1b1b. The Near Eastern leftovers evolved into R1b1a (M18), now found at low
frequencies among the Lebanese and the Druze.The Phoenicians (who came from modern day Lebanon) spread this R1b1a and R1b1* to their
colonies, notably Sardinia and the Maghreb.
The subclades R1b1b1 and R1b1b2 (the most common form in Europe) are closely associated with the spread of Indo-European languages, as
attested by its presence in all regions of the world where Indo-European languages were spoken in ancient times, from the Atlantic coast of
Europe to the Indian subcontinent, including almost all Europe (except Finland and Bosnia-Herzegovina), Anatolia, Armenia, Europan Russia,
southern Siberia, many pockets around Central Asia (notably Xinjiang, Turkmenistan, Tajikistan and Afghanistan), without forgetting Iran,
Pakistan, India and Nepal. The history of R1b and R1a are intricately connected to each others. Whereas R1b1 is found is such places as the
Levant or Cameroon, R1b1b mostly likely originated in north-eastern Anatolia.

It seems like the european halogroup is considered to originate from Asia pretty much, though no it's not for certain. But that does play into what I said earlier about primates being in Asia too. Still I'm not sure man. The article on MDNA also cited the Australia discovery to evolved scientific methods, so it's entirely possible that in a few decades or so our origin will be flipped on it's head again. But I can see Asia and Australia being the starting point for the different groups

Do you believe it's more likely all human life on this planet originated from one spot in Africa? OR it popped up all over the world and we just haven't found other origin points yet?

Its complicated. Let's put it this way: the common ancestor of humans and chimpanzees Definitely lived in Africa (approx 5 million years ago) . But on the 'branch' that would later lead to modern day homo sapiens, there were still further splits, all of which are now extinct. The last line to go extinct were the neanderthals, who up to 40000 years ago occupied Europe and were assumed to be our direct ancestors. DNA tests done by researchers in Germany found differences far too significant for that to have been the case: the new theory is that they were replaced/beaten out of Europe by their hominoid cousins who stayed behind in Africa and evolved independently there. While are there are still 'gaps' over the exact route, one thing is clear: the neanderthal was not our direct ancestor.

As for your Australia links, aboriginals may have evolved from a more primitive homo sub family (like the neanderthals) independently, or our earliest 'human' ancestors managed to get there very early on.

Regardless, we still all came from Africa: the absence of jungles and great apes with well nigh identical DNA to ourselves in existence (chimpanzees) anywhere other than Africa are all proof of our original(more than 3 million year old) ancestry from that continent, whatever the exact routes were.

We're all distant relatives. The question is how distant.
