Back in April I posted about the fossil remains of Luzia Woman found in Brazil. Most anthropologists, including myself, believe she was a Paleo-Indian who may well have been part of the first wave of migrants into South America. The fossil remains have been dated at about 11.5 kya and in terms of all things anthropological that’s not that long ago. In fact, it was towards the end of the last glaciation. You can find my original post at the link below. Continue Reading
Dragon Bone Hill overlooks the sprawling Chinese capital of Beijing (formerly Peking). It is a small limestone mountain visited by over 150,000 visitors each year. It was here in 1929 that the first specimen of Asian Homo Erectus was found known as “Peking Man.” The find consisted of a nearly complete skull dated between 680-780 kyr. The specimen was also one of the earliest ancient human ancestor fossil remains ever found but since that time the fame and importance of Peking Man has dwindled, sadly. Older fossils have been discovered in Africa where environmental conditions for fossil formation are more conducive. China and Southeast Asia tend not to be very good places for finding fossils due to the tropical climate and wet conditions in much of the region. Today Chinese paleoanthropologists wonder if H. erectus died out or contributed genes to modern Chinese people.
In the past decade China has stepped up efforts to uncover evidence of early human ancestors in the country and surrounding region. Old fossils are being reanalysed and old theories are being revised as new evidence comes to light. And the Chinese government has built a million dollar lab to extract and sequence ancient DNA!
More and more paleoanthropologists are beginning to finally pay attention to what is being found and what has been found in China and Asia in general. Discoveries in China and Asia clearly indicate that there was a variety of prehistoric human ancestors in the region and these finds are beginning to challenge some conventional ideas about just what our evolutionary history might really be!
Sadly, Western researchers tend to view fossils and artifacts in terms of those found in Africa and Europe due to the age of the fossils found there and because they are closer to major research facilities. However, what is becoming increasingly clear is that Asian fossils do NOT fit into the traditional narrative of human evolution
H/T to JR Bentley for sending us this research article………..
It would be an understatement to say that there are problems with the Out-of-Africa (OOA) theory and finally new research and reanalysis of prior research is attempting to correct some of those problems but what is being found is that the OOA may be absolutely WRONG to begin with. This becomes especially obvious when genetic evidence is looked at. In fact, WORLD science is now leaving the OOA theory behind and a Chinese research team is advancing an out-of-ASIA theory for modern human origins based on Y-DNA & mtDNA evidence and, thus, they are reviving the Multiregional Theory for human evolution based on autosomal evidence. The field of genetic research is becoming more precise and I think that is fantastic because it is now beginning to give us a new picture of human evolution and migration patterns!! Finally, we are getting some real concrete proof of what was and what was NOT.
The latest research by Chinese geneticists suggests that about 2 mya the first split occurred in modern human autosomes. Further, they’ve uncovered genetic evidence of Y and mtDNA having originated in East Asia and dispersing outward from East Asia via HYBRIDIZATION by archaic human ancestors!! This research strongly suggests a EURASIAN origin rather than an African origin for ancient human ancestors!! The primary research team is being led by Shi Huang who is a US educated and trained geneticist.
Huang’s research confirms genetic diversity is highest in Africans and lowest in Amerindians. His team also confirms Africans & Amerindians are genetically most divergent from each other. Africans are found to be closer to each other than they are to other groups and that New world sub-populations are more distinct from each other than other continental groups. Further, they’ve also found that Amerindians have the world’s highest values of intergroup diversity.
The findings of this research are currently under peer review and the team argues that African genetic diversity is NOT a function of greater age of African hominins but is a product of selection! This is supported by data showing increased African diversity in the study. Yuan uses autosomal molecular divergence dates as evidence for multiregional evolution. That date is derived from estimated molecular divergence between autosomes of major human groups to have taken place 1.96–1.91 mya which is consistent with paleobiological evidence for a Homo (human) migration out of Africa 2 myr.

The link below is to an excellent article well worth the read about the growing “mystery” concerning archaic humans with modern human features. It calls for the revamping of the Out of Africa theory and I wholeheartedly agree!
The norm has always been that more than one human species have coexisted at the same time and sometimes in the same place. Our nice little concept of an archaic human species giving way to a more modern human species now lies in tatters thanks to recent discoveries. That little Utopian idea no longer flies as the evidence says that there was MUCH interbreeding between human species and that HYBRIDS were produced and survived. In fact, they dominated and they (we) still dominate today!
In South Africa we have Homo naledi showing a mix of archaic and modern morphology. We have the same in Morocco. These finds are changing what we think in terms of human evolution because these specimens are NOT from archaic times but from MODERN TIMES! When I say modern times mean around 300 kya NOT millions of years ago. The “mystery” is really no mystery at all if we think in terms of hybrid offspring. What is being found in Morocco and South Africa and elsewhere is CLEAR EVIDENCE of hybridization! And not only that but we now know that there were many migrations out of Africa AND many migrations INTO Africa! So much for the OOA theory!! Continue Reading
A new look at archaic human DNA by the University of Utah has come to some interesting and “revolutionary” findings but sadly what they have found doesn’t fit at all with the status quo so it’s being ignored. However, I STRONGLY suspect that what the U of U has found is closer to the TRUTH in terms of the human evolution story than what we have now!
Using a new method for analyzing DNA sequence data researchers at the University of Utah have reconstructed the early history of archaic humans and it contradicts what we believe to be so for modern humans (H. sapiens), Neanderthals, and Denisovans. One thing they discovered quickly was that Neanderthal and Denisovan populations almost went extinct but 300 generations later the Neanderthal population grew to TENS OF THOUSANDS of individuals living in segregated populations, that is, they mainly lived apart from Denisovans and modern humans.
“This hypothesis is against conventional wisdom, but IT MAKES MORE SENSE that the conventional wisdom,” said Alan Rogers who is a professor of Anthropology and lead author of the study. And indeed it does!! The conventional wisdom holds the view that Neanderthal numbers were small when modern humans came upon the scene…somewhere around 1000 individuals. But this study shows that that number grossly underestimates the Neanderthal population at the time. The team calculated that Neanderthals and Denisovans separated around 744 kya which is much earlier than conventional wisdom holds. The study also questions the conventional wisdom that Neanderthal populations only amounted to about 1000 individuals and that the REAL Neanderthal population may have numbered in the tens of thousands!!

Cerutti Mastodon Site in San Diego, California discoveries indicate that early humans were in North America at least 130 kya.
Calico Hills Early Man Site in California indicate humans were in North America 100-200 kya.
Bluefish Cave Site, Canada indicates humans were in North America 24 kya.
Puebla, Mexico Site indicates humans were in Mexico 200-250 kya
Pedra Furada Site in Brazil indicate humans were in South America 48-60 kya.
And there are more…………….
When we take a look at these sites and the dates they have yielded we find that it appears humans have been in the Americas since 250-200 kya. But this is far from being the generally accepted timeframe for when humans migrated into the Americas! That timeline says we migrated across the Bering Landbridge around 15 kya! However, the more archaeologists discover, the more it appears that “someone” was in the Americas before 15 kya and that “mystery population” is affectionately known as “POPULATION Y.” Additionally, the more we learn about Paleoindians the more apparent it becomes that they did NOT look like modern Native Americans and, in fact, were quite different. At the tip of South America we have a people known as the Fuegians who ironically have many features sen in Homo erectus and we find the same features in a people known as the Pericues who lived at the tip of Baja California. But, according to mainstream thinking H. erectus was long extinct before these timeframes. I suggest that hypothesis is WRONG and note that some researchers believe H. erectus could have existed up until 20-30 kya!! Continue Reading
A new study and find has come out and in my mind it is MAJOR NEWS when it comes to ancient human ancestors being in North America. The San Diego Natural History Museum has announced that a recent Mastodon discovery shakes up our beliefs of when early man came to North America and the evidence comes from broken bones and rocks.
At an Ice Age site in San Diego, CA bones 130 kyr and teeth from a mastodon show evidence of EARLY HUMAN modification. Analysis of these finds dramatically alters the timeline for when humans first arrived in N. America. The report was published today in the journal “Nature.”
Museum paleontologists discovered the remains during routine work to clear the way for a new freeway expansion in the area. The discovery includes bones, teeth, and tusks and many of them have been sharply broken. They were buried alongside large stones that apparently were used as hammer stones and anvils. This makes the site the oldest in situ and well documented site in North America according to the museum.
According to Judy Gradwohl who is president and CEO of the Museum this discovery rewrites our understanding of when “humans reached the New World.” She went on to say, “The evidence we found at this site indicates that some HOMININ SPECIES was living in North America 115,000 YEARS EARLIER than previously thought.” Did you get that? SOME HOMININ SPECIES! That’s CODE TALK! Why didn’t she say Homo sapiens, or modern humans, or something along those lines? Instead she uses the phrase “some hominin species.” Why” Because I bet they suspicion this “hominin species” was NOT modern humans!!
Gradwohl went on to state, “This rasises intriguing questions about how these EARLY HUMANS arrived here and WHO THEY WERE.” In other words they don’t know who these early humans were and they don’t even know if they were early modern humans are some more archaic human like HOMO ERECTUS! And I’m betting my money on HOMO ERECTUS! In my mind this is evidence of this species being in the Americas around 100 kya!! Continue Reading
