Trees! What Trees? All I see is a forest...

Races have evolved away from each other over the past 10,000 years, according to new research that challenges standard ideas about the biological significance of ethnicity.

A genetic analysis of human evolution has shown that rather than slowing to a standstill it has speeded up, with different pressures on different populations pushing racial groups further apart. Scientists behind the findings suggest that European, African and Asian populations grew genetically more distinct from each other over several thousand years, as their environments took them down different evolutionary paths.

the new work indicates that variations tend to differ between races, and that these became more, not less, pronounced.

“Human races are evolving away from each other,” said Henry Harpending, Professor of Anthropology at the University of Utah, who led the study.

“Genes are evolving fast in Europe, Asia and Africa, but almost all of these are unique to their continent of origin. We are getting less alike, not merging into a single, mixed humanity.

Humans are evolving at a faster rate than at any time in history, according to a study.

Scientists say the speed of natural selection has accelerated so much that within a few generations we will have evolved resistance to diseases such as diabetes and malaria.

Instead of people from different parts of the world becoming more alike over time, they have actually been diverging, the study suggests.

The research showed that the population explosion since the Ice Age 10,000 years ago had accelerated the rate of genetic change.

"The dogma has been these are cultural fluctuations, but almost any temperament trait you look at is under strong genetic influence.

…two papers in this week's Proceedings of the National Academy of Sciences.. One of the papers, written by Andrea Migliano and her colleagues at Cambridge University…The other, by Robert Moyzis of the University of California, Irvine, and his colleagues…..how much evolutionary change has happened since Homo sapiens climbed out of his African cradle and began to colonise the world? The answer is, quite a lot—and the rate of change seems to have speeded up.

What they have found is that about 1,800 protein-coding genes, some 7% of the total known, show signs of having been subject to recent natural selection. By recent, they mean within the past 80,000 years. Moreover, as the chart shows, the rate of change has speeded up over the course of that period.

The paper Dr Moyzis and his colleagues have just published is a ranging shot, but the amount of recent human evolution it has exposed is surprising. Others will no doubt follow, and the genetic meaning of the term “race”, if it has one, will be exposed for all to see.

The research showing pronounced racial differences between the peoples of Europe, Asia and Africa, is ever growing and increasingly undeniable. And the research is demonstrating scientifically what has been evident all along, which is that different races have different capacities in intellect, skill and ability. The consequences of denying this reality will soon be upon us, as the significance of racial differences have been spelled out in such works as, ‘Why Race Matters’ by Michael Levin, Ph.D., ‘Race Differences in Intelligence’ by Richard Lynn, Ph.D. and Race, Evolution, and Behavior by Philippe Rushton, Ph.D. as well many others…

What does this mean for America?

In ‘IQ and the Wealth of Nations’ by Prof. Richard Lynn, it was demonstrated that IQ levels match civilization levels; meaning the higher the IQ, the higher the standard of civilizational standard, the lower the IQ, the lower the civilizational standard. Europeans averaged an IQ of 100, Africans 67 and Native Americans 85. African-Americans (who are partially –upwards of 25%- European) generally average an IQ of 84 and Mexicans (who are mostly Indian with a small percentage of Spanish genetics) average an IQ of 87.

When looking at U.S. population growth by race and ethnicity, quite different stories emerge: For the non-Hispanic white population, the ratio of births to deaths is nearly equal: almost 1:1. Demographers would say that this represents no natural increase in population size. Hispanics, on the other hand, have 8 births for every death, leading to a significantly larger growth rate than that for non-Hispanic whites.

The United States receives about 20 percent of the world's international migrants, but the United States accounts for just 5 percent of the world's population.

The population of America in 1950 was nearly 90% white with a national IQ of 100.
The population of America in 2050 will be nearly 70% non-white and will have a national IQ of 86...
America, by then, will have three times the population it did in 1900. It will be an overpopulated mass of third world people with low IQ and no skills, in a nation running low on both food and water resources.
America at that point will look like a cross between Rwanda and Sao Paolo Brazil.
