Cro-Magnons and the Neanderthals

The genetic evidence proves that there was no interbreeding between Cro-Magnons and Neanderthals - as this article states ;

But this applies only to Cro-Magnons - the ancestors of all Modern White Europeans who evolved in Europe around 60,000 - 40,000 years ago.

Now this evidence states that breeding with Neanderthals did occur but only with those populations around the North African coast and with human populations in eastern Asia.

Therefore the Cro-Magnon people are not just an offshoot of Homo Erectus, we are a Homo-Erectus only hominid species - unlike the North African and Eastern Asia contemporary populations.

Cro-Magnons have NO Neanderthal DNA - and modern Europeans are descended solely from Cro-Magnons.

The North African populations are a mixture of Homo Erectus and Neanderthal as are those from Eastern Asia.

The DNA evidence shows that DNA from a separate hominid species, the Neanderthals, is present in those human populations and was transmitted on two occasions.

Therefore their is a species differential as well as a genetic differential.

Perhaps we have evidence here of a racial difference - with the North African populations related to African populations and the Eastern Asia to oriental populations ?

This rewrites the entire history of humanity.

But dont expect it to be taught in your schools.

We may all be a little bit Neanderthal as study finds species interbred twice with humans

It won't come as a surprise to anyone wandering around Britain's city centres late on a Friday night. But scientists have discovered that most people have a little bit of Neanderthal man in them.

A major DNA study suggests that our ancestors interbred with the Neanderthals at least twice tens of thousands of years ago - and that their genes have been carried down the millennia ever since.

The discovery adds to the mystery surrounding the Neanderthals, an offshoot of the human family tree who vanished in Europe around 25,000 years ago.

A new study suggests that most of us have some Neanderthal genes in our DNA. Scientists believe our ancestors may have bred twice with the extinct species

Some researchers have argued that the Neanderthals were driven to extinction by modern humans. But others say the two species merged.

The new findings come from a genetic analysis of nearly 2,000 people from around the world.

Dr Jeffrey Long, a genetic anthropologist at the University of New Mexico, who carried out the study, said: 'It means Neanderthals didn't completely disappear.'

He added: 'There is a little bit of Neanderthal left over in almost all humans.'

Many scientists believe that modern humans evolved in Africa between 200,000 and 100,000 years ago. Our ancestors left Africa around 60,000 years ago and migrated around the world - replacing other branches of the family tree which had left Africa earlier - including the Neanderthals.

By 25,000 years ago the Neanderthals had vanished from Europe.

Some experts believe they interbred with modern humans, others that they were driven to extinction by changing climate or competition for food.

The latest study looked at DNA from 1,983 people living in Africa, European, Asia and the Americas.

Scientists, led by Dr Sarah Joyce at the University of Mexico, then created an "evolutionary tree" to explain how and when differences in the DNA between people from around the world appeared.

She found that the best explanation was if there were two periods of interbreeding between modern humans and another human species - and that Neanderthals were the only likely candidate.

One period of interbreeding occurred around 60,000 years ago in the eastern Mediterranean, the other around 45,000 years ago in eastern Asia.

The two events happened after our ancestors migrated out of Africa to colonise the rest of the world. The researchers found evidence of interbreeding between Neanderthals and modern Africans - supporting the theory.

The findings were presented at the American Association of Physical Anthropologists conference in New Mexico and have triggered huge excitement among experts in human evolution.

Dr Noah Rosenberg, an anthropological geneticist at the University of Michigan in Ann Arbor, told the journal Nature: 'They are onto something.'

The findings support scientists who believe there is evidence of interbreeding in fossils.

Neanderthals had thick set features and heavy foreheads. They were around six inches shorter on average than modern people, but their brains were 20 per cent bigger.

In recent years, scientists have found evidence that they were more sophisticated than their popular image, and may have developed language.

They used flint and stone tools, and were excellent hunters. They supplemented their diet of deer, bison, boar and bear with seal, fish, shellfish, nuts, grains and plants.
It may not take long for the new theory to be proved.

Other researchers from the Max Planck Institute, led by Svante Pääbo, completed the first draft of the complete Neanderthal DNA last year.

The results are expected to be published soon and may shed more light on breeding between the two species.

Re-The genetic evidence proves that there was no interbreeding between Cro-Magnons and Neanderthals
You want to come to the Valleys on a Friday night ;o)

I am big into basis of anthropology ,me and the Gwent organiser are officially known as "the forehead spotters"
You will notice that in the most violent Countries on the planet, i.e. Sierra Leone; the vast majority of population has small cranium that slopes backwards from the eyebrow line and the subject usually has a large mandible, much the same as a Gorilla.
Less frontal Lobe,together with a smaller or under developed upper cerebral hemisphere= underdeveloped social skills ,with less ability to control involuntary basic instincts that is controlled and subconsciously directed by lower brain function.
A brief example-
When we are intoxicated, many people become sexually deviant ,aggressive and very often flushed.The upper hemisphere shuts down and the Hypothalamus/Lower brain function takes over; controlling heat regulation ,hunger ,sex drive,anger, etc.."what we need to survive"
Westerners have a distinctly high forehead, that stays the same width almost to the top, with many slight variations.
You will look at a china man and immediately visually identify him, the same can be done with our people if you know what you are looking for.
I look at it like this, we have "Orangutans, chimps,Gorillas,baboons etc, we are the same in comparison,we are all pre-determined or should I say and/or pre-disposition 'd to be articulate, aggressive etc etc.

It is absolutely no mistake that Western Society have developed because of our genetics, that I will add, is completely out of our control.
There is no such thing as a 3rd World Country, there are 3rd World people and nothing will ever ever change nature or for you believers "Gods way" !!

Further to this ,re -
Now this evidence states that breeding with Neanderthals did occur but only with those populations around the North African coast and with human populations in eastern Asia.

I wrote a fairly lengthy comment on the main BNP web about 3 years ago very similar, they didn't publish it , but I must say, it wasn't so PC freindly..

Within the Communist manifesto, unfortunately there is no modern science and if there was it would as it is now , to be forbidden.
We are stepping back 100,000's of years in evolution and thats on the bright side if other races can evolve!!
