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.

Hypertrichosis seen in a young man
I got an email a while back and this post is in answer to that email but first here is the email with the name changed to protect the reader:
Dear Dr. Peron:
I realize you are an anthropologist and not a medical doctor but do you know anything about excessive body hair growth at birth? If so, can you put up a post about it? Here’s why I am asking you this question.
When I was born I had a reddish “fur” all over my newborn body. Probably it was hair but my grandparents described it as “fur” like that seen in a little monkey or puppy. I also had a projecting jaw that was corrected by orthodontics when I was about 13 years old, thankfully. I also had a somewhat flat nose and pointed ears. In fact, my grandparents, aunts, uncles, etc. said I looked more like a ” baby ape” than a “human baby.” I lost the “fur” during the first few years of my life but retained a colorless hair type all over my body which kind of shines like a blond color when I am in the sun. I know this might all sound freaky but my family is reluctant to talk about this and my mother gets very angry and absolutely refuses to discuss it whenever I bring it up. Additionally, when my father arrived at the hospital (he was off somewhere and had to travel) he took one look at me and angrily said, “That’s not my son!” and stormed out of the hospital never to return. Needless to say he and I did not have a very good relationship when he was alive, unfortunately. I just want to know if you’ve ever heard of anything like this and if you can post a bit about it if you have.
Miguel I’m not claiming to be an expert in this subject but here are some things that might aid in your understanding of this phenomena. Also, note that things like this DO happen so you are NOT alone.
Before I begin let me define a few terms. First is the term “atavism.” An “atavism” is a term used in biology to describe an “evolutionary throwback.” Traits appear in a species or individual that have generally disappeared generations before. Atavisms can occur in several ways. One way, and the most common, is when genes for previously existing phenotypical features are preserved in DNA and they become expressed through a mutation that knocks out the overriding genes for the new traits OR makes the old traits override the new one(s). A number of traits can vary as a result of shortening of fetal development of a trait (neoteny) OR by prolonging of it (neoteny). In such a case a shift in the time a trait is allowed to develop before it is fixed can bring about an ancestral phenotype. I do not wish to insult you so please do not take what I’m writing that way. What you are describing comes closest to the ancient human ancestor species known as Homo habilis (aka: Tool Man, Handyman, et al) minus the heavy brow ridge. This species existed roughly between 2.1–1.5 mya. That in my mind is significant and if you have any pictures of you as a newborn with this condition I would be HIGHLY interested in taking a look at them. Continue Reading
Let me begin this post by defining some terms that some of you might not be familiar with. First is the term “Atavism.” In biology an atavism is an evolutionary throwback. What this means is that traits sometimes reappear in some people or some species that had disappeared generations ago. For example, a newborn human infant covered in somewhat thick hair would be considered an atavism as such an infant would be deemed an “evolutionary throwback” and might look like something akin to, say, Homo habilis.
