Blondes and the ice age

[Approaching Infinity]

Very, very interesting!

I think this calls for a new hit list...

My thought exactly, it may also be a good question for the C's ie the common ancestor & if there was such, they have indicated that the races have meaning to them, one of which is just for the heck of it, ie an experiment.

If there was a common ancestor as per the paper, the "Adam" thing would really take on a new light. ;)

Besides agreeing with what others just said, I was also thinking that this must have to do with what the Cs said about the nordic genes that were mixed with the gene pool already available on earth.

There are also researches that said about the Toba Eruption event [ _http://en.wikipedia.org/wiki/Toba_eruption ] having occurred between 69,000 and 77,000 years ago, which could have coincided with the beginning of the last Ice Age. That is no too far away from the probable arrival of the Kantekkian folks (80,000 ago). If they came in hundreds of millions, and there was just a catastrophic event on earth too, the new comers must have become -at that time- at least half of the earth population (or even more), due to the reduction of native peoples after such a cataclism. I think that could be taken into account.

Also a cataclism, must be a very good chance for 4D STS folks to introduce massively new genetic pools, in the middle of the turmoil, without being openly noticed by the already existing modern humans.

In the article linked above (about the Toba eruption), it says:

According to the supporters of the genetic bottleneck theory, between 50,000 and 100,000 years ago, human population suffered a severe population decrease—only 3,000 to 10,000 individuals survived—followed eventually by rapid population increase, innovation, progress and migration.[26] Several geneticists, including Lynn Jorde and Henry Harpending have proposed that the human race was reduced to approximately five to ten thousand people.[27] Genetic evidence suggests that all humans alive today, despite apparent variety, are descended from a very small population, perhaps between 1,000 to 10,000 breeding pairs about 70,000 years ago.[28] Note that this is an estimate of ancestors, not of total human population. Isolated human populations that eventually died out without descendants may have also existed in numbers that cannot be estimated by geneticists.

Ambrose and Rampino proposed in the late 1990s that a genetic bottleneck could have been caused by the climate effects of the Toba eruption. The supporters of the Toba catastrophe theory suggest that the eruption resulted in a global ecological disaster with extreme phenomena, such as worldwide vegetation destruction, and severe drought in the tropical rainforest belt and in monsoonal regions. Τhis massive environmental change created population bottlenecks in species that existed at the time, including hominids;[29] this in turn accelerated differentiation of the reduced human population. Therefore, Toba may have caused modern races to differentiate abruptly only 70,000 years ago, rather than gradually over one million years.[30] Robock believes that, indeed, a 10-year volcanic winter triggered by YTT could have largely destroyed the food supplies of humans and therefore caused a significant reduction in population sizes.[31]

However, research by archaeologist Michael Petraglia's team cast doubt on Ambrose's theory. Petraglia and his team found stone tools in southern India, above and below a thick layer of ash from the Toba eruption. The tools from each layer were remarkably similar, and Petraglia says that this shows that the huge dust clouds from the eruption did not wipe out the local population of people:[33][34][35][36][37]

Whoever was there seems to have persisted through the eruption.

Evolutionary biologist Richard Dawkins has postulated that human mitochondrial DNA (inherited only from one's mother) and Y chromosome DNA (from one's father) show coalescence at around 140,000 and 60,000 years ago respectively. In other words, all living humans' female line ancestry trace back to a single female (Mitochondrial Eve) at around 140,000 years ago. Via the male line, all humans can trace their ancestry back to a single male (Y-chromosomal Adam) at 60,000 to 90,000 years ago

Well that certainly redefines "Cougar" for me...

When I think about this, so many questions come up, but that is science for you. For example, I wonder how blood types figure in to this if at all, and what of OPs.
