Neanderthal-human trysts may be linked to modern depression, heart disease

Ancient trysts between Neanderthals and modern humans may have influenced modern risks for depression, heart attacks, nicotine addiction, obesity and other health problems, researchers said.

Some of the scientists' discoveries confirm previous ideas. For example, earlier research suggested that Neanderthal DNA influenced skin cells known as keratinocytes that help protect the skin from environmental damage such as ultraviolet radiation and germs.

The new findings suggest that Neanderthal genetic variants increase the risk of developing sun-triggered skin lesions known as keratoses, which are caused by abnormal keratinocytes.

The Neanderthal Theory

In the past there have been numerous theories for the cause(s) of neurodiversity conditions like Autism, Asperger's syndrome, ADD/ADHD, OCD, Social phobia, Dyslexia, Dyscalculia, Bipolar, Schizophrenia, Tourette and Dyspraxia. 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 neurodiversity with little success.

This theory approaches the problem from a new radical viewpoint. Instead of approaching neurodiversity conditions as disorders, brain defects or the result of poor socialization or parenting, it claims that neurodiversity is fully functional human variation.

All the areas that are central to neurodiversity are related to species-typical adaptations that vary widely between species. These include nonverbal signals, social organization, sensory acuteness, perception, motor skills, general preferences, sexuality, courtship, physical traits and biological adaptations. Some of this diversity 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 Neanderthals contributed at least 1-4% to the non-African genome. Aspie Quiz have demonstrated in a large survey in the US population that Afroamericans have only 1/6 of the autism incidence of non-African groups.

Principal Component Analysis (PCA) of Aspie Quiz yields axes 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 Eurasia. In Caucasians, these axises seems to be 1.8 million years, 150,000 years and 33,000 years. In Asians, they seem to be 1.8 million years, 130,000 years and 44,000 years.

There seems to be a hidden assertion that the homo sapien line was perfect until Neanderthal DNA added dysfunction to it. If only we'd picked our own cotton broken our own rocks.

"There seems to be a hidden assertion that the homo sapien line was perfect until Neanderthal DNA added dysfunction to it."

The Neanderthal brain was larger than the modern human brain and studies have shown that larger brains equals higher IQ. We may have gotten a higher IQ from Neanderthals.

Any way, We Are Neanderthals.

Frances McDormand, is that you?

I seriously doubt it was “trysts”.

Imo, more likely, it was the old school rules of conflict. Kill the men and boys, take the women and girls as slaves with the randomly selected slave getting passed around the campfire on cold nights.

Er no. Science is “if you place a fulcrum a a certain point the mechanical gain will be ‘x’ and it will be ‘x’ every time a fulcrum is placed so”.

“Might” or “may” is pseudo-science.

Might or may is pseudo-science.

OMG, pseudo science? You need to go back and review your notes from your history of science course.

Science is a process, not an outcome.

[Seruzawa]

Well by your standards algore is a great scientist. I’ll still with repeatable predictable experimental results, not “could be” or “might”.

Blam, you and I are close in age did you ever hear of Autism when we were kids?

I have met Lady Jane, I would advise you not to get into a P*ssing match with her.
