Skip to comments.Aspergerís Man- The Search for Multi-Regional Human Speciation
Posted on 08/30/2012 10:45:34 AM PDT by EveningStar
My first love will always be archaeology and the study of what makes us human.This article is speculation. This is my personal musing on the development of certain psychological and physiological human traits. This is not to be taken as anything but my personal opinion. I have no evidence that there was an Aspergers man. This article was also written several years ago and since then more evidence for the possibility of interbreeding with other hominids has come to light in Russia and in Africa that may support my original idea...
save for later
It’s an interesting theory, but I see one fatal flaw: the clumsiness associated with aspies would be fatal for a hunter, wouldn’t it?
(And I say this as someone who’s immediate family believes he’s on the spectrum)
The clumsiness may be a condition caused by two conflicting genes that would not be present in a pure Homo sapien or pure Asperger’s man. Also the clumsiness may be a product of heightened senses (you get something, something is taken away there is no free lunch).
In the past there have been numerous theories for the cause(s) of autism, Asperger's syndrome, ADHD and Tourette syndrome. Most of these theories can at best explain small parts of these diverse syndromes. Many of them extend their findings in spectacular ways to be able to claim to explain larger parts of the autism spectrum with little success.
This theory approaches the problem from a new radical viewpoint. Instead of approaching autism as a disorder, brain defect or the result of poor socialization or parenting, it claims that autistics are fully functional.
All the areas that are central to autism are related to species-typical adaptations that vary widely between species. These include nonverbal signals, social organization, sensory acuteness, motor skills, general preferences, sexuality, physical traits and biological adaptations. Some of this diversity in autistics is poorly understood and virtually unresearched and therefore is not published in peer-reviewed journals. Because of this lack of research, Aspie-quiz, an online questionnary, is heavily referenced for these traits.
Recent genetic research have demonstrated that the Out-of-Africa (OoA) model with no interbreeding fails to explain nuclear DNA diversity in Eurasia. Several models of interbreeding that do explain this diversity exists today. It therefore is quite likely that Neanderthals contributed to the Caucasian genome. Aspie-quiz have demonstrated in a large survey in the US population that Afroamericans have only 1/6 of the autism prevalence of Caucasians. The same survey also indicates that Asians and American Indians have about 1/2 of the autism prevalence of Caucasians.
Principal Component Analysis (PCA) of Aspie-quiz yields axises that seems to be related to the first Eurasian Homo, the formation of modern humans in Africa or South Asia and the hybridization between modern humans and Neanderthals in Europe. These axises seems to be 1.8 million years, 150,000 years and 37,000 years, which fits pretty good with the archaeologic evidences available.
The conclusion that should be reached from the article is that we may need to look for a third (not counting denisovan man) hominid that would account for Asperger traits rather than autism traits. Autism and Aspergers are grouped together because they seem to have many of the same or similar “dysfunctions”. Aspergers and Autism have been grouped incorrectly in my opinion. There are some major differences in the two disorders.
Aspergers has no speech delay associated with it.
Aspergers are not anti social while those with autism are. Those people with Aspergers are social with smaller groups and form more intense bonds along lines of common interest.
Aspergers are obsessive but can switch obsessions much more easily than those with autism. Many Autistics can not function on any level outside of their single narrow focus.
The biggest difference is cognitive. Many with autism have some form of retardation associated with their disorder. Aspergers is not symptomatic in low intelligence individuals.
Your desire for another human group is not that far fetched. (As you know) The Denisovans are new and I just read about another extinct human that was found in only the genes of Africans... DNA will open many more doors.

Thanks EveningStar. It's a vanity post by proxy, I guess. :')
I’m aspiie. Happens.
Glad you rode the storm okay. I enjoy your posts. Keep on. Take care brother.
Fascinating. It’s outside the box stuff like this that keeps me coming back to these threads.
