Good article.

"The results suggest that European populations have proportionately more harmful variations, though it is unclear what effects these variations actually may have on the overall health of Europeans."

How can they call them 'harmful variations' if they don't know what effect they have? Maybe they're beneficial variations, huh?

[Bob J]

An increase in variations would also lead to more posotive variations and may explain europeans quicker development.

35 person study,

garbage science for political gain.

This is no different than those 10 brains examined to determine nature vs nurture.

[longtermmemmory]

this makes me think of the concept that all the weak ones die out.

The immediate flaw in this study is that there is no qualitative to the genetic study just number of variations. (extremely suspect)

How do we know that the elimination of those variations was not in fact a positive to survival.

Kind of like a format war. The most universal format survives the longest.

I wonder how this jibes with the people from the basque region of spain. They are supposed to be the most genetically unique people.

"I wonder how this jibes with the people from the basque region of spain. They are supposed to be the most genetically unique people."

No they're not...their yDNA is overwhemingly R1b as is 68% of all Europeans and as high as 90% among the Irish.

You must be thinking about their unique language.

If we fast forward to 12,000 years ago (Map 2), the ice has retreated and the land has become much more supportive to life. Many animal species have returned to inhabit the land, although the snake, harvest mouse and mole never made it as far as Ireland before the land bridges re-flooded (ever wondered why there are no snakes in Ireland?).

Map #2

The three groups of humans had taken refuge for so long that their DNA had naturally picked up mutations, and consequently can be defined into different haplogroups. As they spread from these refuges, Haplogroups R1b, I and R1a propagated across Europe.

- Haplogroup R1b is common on the western Atlantic coast as far as Scotland.
- Haplogroup I is common across central Europe and up into Scandinavia.
- Haplogroup R1a is common in eastern Europe and has also spread across into central Asia and as far as India and Pakistan.

These three major haplogroups account for approx 80% of Europe's present-day population.

Around 8,000 years ago (Map 3), the Neolithic peoples of the Middle East that had developed the new technology of agriculture began moving into Europe. There were several haplogroups involved, mainly E3b, F, J2 and G2.

Map #3

These Neolithic haplogroups came in several waves over time and are found predominantly along the Mediterranean coast. Around 20% of the present-day population are from these Neolithic haplogroups. What is interesting to note is that the agricultural technology spread much further than the people who first 'invented' it.

A little later, around 4,500 years ago, Haplogroup N3 began moving across from west of the Ural mountains. Haplogroup N3 follows closely the spread of the Finno-Ugric languages.

Too bad about agendas.

The Neandertal Enigma
by James Shreeve

Frayer's own reading of the record reveals a number of overlooked traits that clearly and specifically link the Neandertals to the Cro-Magnons. One such trait is the shape of the opening of the nerve canal in the lower jaw, a spot where dentists often give a pain-blocking injection. In many Neandertal, the upper portion of the opening is covered by a broad bony ridge, a curious feature also carried by a significant number of Cro-Magnons. But none of the alleged 'ancestors of us all' fossils from Africa have it, and it is extremely rare in modern people outside Europe." [pp 126-127]

Well the obvious fact that there are vastly more European American makes this one of the utlimate "ah DUH" stories

Only problem for this line of research is the "African-American" genes they are comparing have been so interbreed with European genes over the centuries that they represent a hybrid, not a pure bred strain.

[ZULU]

“A Cornell-led study, reported in the Feb. 21 issue of the journal Nature, compared more than 10,000 sequenced genes from 15 African-Americans and 20 European-Americans. The results suggest that European populations have proportionately more harmful variations, though it is unclear what effects these variations actually may have on the overall health of Europeans. “

Politically correct biological tripe.

Not satisfied with attacking European civilization - which is the parent of American society and culture, they are now attacking our biology.

Interesting article though - after you slice through the tripe.

[ZULU]

The facts are there, but INTERPRETATION of the facts are warped by the increasingly self-destructive nature of western caucasions.

I’m white and proud of it, and proud of my European heritage.

I don’t need to apologize for anything and I’m sick and tired of masochistic myopic white academics attacking MY heritage.

[Little Bill]

Calm down Blam is a good man. I don’t believe in the out of Africa theory myself for reasons other than genetics, mainly because it is a tautology, and I hate those things.

"Only problem for this line of research is the "African-American" genes they are comparing have been so interbreed with European genes over the centuries that they represent a hybrid, not a pure bred strain."

Maybe.

I was thinking something similar when I saw the picture of the 'African-American' female in the picture above. She seems to have more European facial features than African.

"I don’t need to apologize for anything and I’m sick and tired of masochistic myopic white academics attacking MY heritage."

I'm in agreement with that sentiment.

I wasn’t attacking the poster, I was attacking the article’s premise.
