Interbreeding between humans, Neanderthals, Denisovans...

Post Reply New Topic

Remarkable progress is being made unravelling the detailed evolution of all life on the planet by analysing DNA. Here is a fascinating article about early human evolution.

What about the theory that Autism is related to Neanderthal/Human interbreeding?

Lets look for Autism in Papua New Guniea, if there is more Autism, we can prove the theory!

According to 23and me, I have 2.9% Neanderthal genes.

Now they are saying that human also interbred with Denisovans?

And what about this "another extinct population of archaic humans that lived in Asia more than 30,000 years ago, which is neither human nor Neanderthal."?

So fascinating.

To borrow a (para)phrase from the eugenicists:

Why do we not apply what we know about the breeding of animals to the breeding of humans, for the betterment of the species??

Well, what do we know about the breeding of animals?? We've known for a long time that breeding siblings, or for that matter close cousins, really isn't the greatest idea.

Pet owners know that, while purebred animals have predictable and desirable traits, mixed-breed animals tend to be healthier.

We've learned the hard way that undesirable things happen when you try too hard to improve upon desirable traits (to the detriment of several large dog breeds).

Or, to put it into Redneckese:

GOOOOOO, HYBRID VIGOR!! !!

I wonder how much more research it's going to take to force us to re-evaluate our ideas of "good," "desirable," "normal," and possibly even "human," and come back to using phrases like "It takes all kinds to make a world" as more than polite lip-service.

It would be easier to disprove it: find someone without Neandertal DNA with autism.

Apparently (pure) Africans don't have Neanderthal DNA, it is something associated with the humans that left Africa many millennia ago, is there much/any diagnosis of such African people with autism?

Hoimo Sapiens will screw anything they can get their prehensile appendages on.

The Autism Community of Africa(ACA) was founded in 2007 by Mrs. Brigitte M. Kobenan, the mother of a child with Autism. As she shared her experience with friends and families in the United States and in Africa, she realized that she was not alone. Many families had at least one child with Autism. However among some African families, parents felt ashamed or afraid to disclose their child's condition for fear of being judged or rejected.
In Africa, the lack of awareness and resources prevent most children with Autism to have the necessary tools and treatment to monitor and/or improve their condition. Thus many times, they become a burden for families and communities.

Regarding neanderthals, there's been a debate about whether or not they were actually part of the same species as homo sapiens, considering that they found neanderthal DNA in modern humans. I think that I read about a theory at one stage that a male neanderthal could produce viable offspring with a female homo sapien but a male homo sapien could not produce viable offspring with a female neanderthal (there is no neanderthal mitochondrial DNA in any modern humans despite the fact that neanderthal DNA makes up 4% of the DNA of Caucasians). So, considering that the biological definition of species involves a population in which individuals can reproduce and produce viable offspring, would neanderthals still be considered the same species if it were true that viable offspring could only be produced from the pairing of a male from the one group and a female from the other but not the reverse? Because if that were true, it would seem to me that such pairings were only partially successful at producing viable offspring, like there are some rare occasions when female mules could produce offspring too as a comparison.

i had never realized there were neanderthals living in West Verginia

Huh?

Where does it say anything about West Virginia ( or ' Verginia' , as you call it. Lol!).

my post was a joke.in america there are stereotypes about inbreeding in the appalachian area virginia,west virginia,kentucky ect......

your right, i spelled" Virginia" wrong,i miss letters when i try to type fast

Thats why I didnt get it. I hope that you're aware that the article is about the polar opposite of the subject of your joke. The article is about OUTbreeding with other species of hominids. Not about INbreeding.

i understand the concept of genetic sequencing and how a DNA profile can reveal thousands of years of genenic history.
the only thing i know about neanderthals is that they died out because they used primitive weapons whereas archers from the high plains of western mongolia used bow and arrows.so they survived because of more efficient hunting techniques.

this scenerio repeated itself 1000's of years later in the context of war when mounted archers like mongols,turks and huns became the greatest warriors in the the worlds history with sophisticated weaponry.in the hieght of Atilla's empire he controled from Paris to Bejing approx. in modern terms.atilla even had a chance to take constantinople but he chose not to take,likely because the huns had no use for anything but money,gold or wives of wealthy men to sell for ransom.a symbolic conquest like the capitol of the roman empire meant little to the huns.

chengis khans empire extended from the black sea to japan and 1 out every 200 people alive on this planet are living relitives of chengis khan.

the turks came from central asia and by 1453 controled western mongolia and china,the indian sub continent and the middle east as far west as constantinople/instambul and much of south eastern europe


also the mounted archers of central asia invented not the modern violin but the basic concept of the fiddle

Three cheers for us Homo Sapiens and our prehensile appendages!

I think Ruvyen meant retractable appendage
