"those who are not required to breed"
oh my god.... you certainly are not one of those that should get children.

speed said:And one more thing Norsemaiden:
White civilization if you will--and by that I mean Scandinavian, Celtic, and Germanic civilization--really didnt get started until the late middle ages.
infoterror said:This isn't as cut and dry as one might think. First, there's India. Second, there's the long record of civilization in Finland. Then there are other indicators from the center of Europe, not to mention Solutreans found in the USA at 13,000 years ago. My guess is that Spengler was right: the bravest civilizations don't leave monuments or bother to write much down in "permanent" form.
so should the people incappable of raising a healthy child be sterilised???Final_Product said:You sort of missed the point. Eugenics is not a clinical form of facism, Its generally an informed point of view that advocates only folks of good stock can breed. Not necessarily only smart people, but just people who can raise a healthy child that can benefit society in a positive way.
Norsemaiden said:But I was asking you a question, not making an argument, so where is your answer? Did I sum up your position correctly? Are you a Jehovah's Witness or something like that? Strawmen don't come into it!
the alumnus said:really? i saw no question marks or any other indication that it was an interrogative sentence. it looked rather declarative.
1)no answers until i read questions
2)no, you didn't
3)no, i'm not

speed said:And one more thing Norsemaiden:
White civilization if you will--and by that I mean Scandinavian, Celtic, and Germanic civilization--really didnt get started until the late middle ages. The Germans, Celts and Scandinavians were all rather savage people, tied to tribal loyalties, with few if any cities nor scientific discoveries. It took contact with the Romans to start this civilizing process, and even then, it took them more than a thousand years.
Furthermore, civilization was started by Semitic peoples not whites--although there are remains of civilization in Western India, and the Minoans are of unknown ancestry.
Thus, perhaps it will take a long amount of time for the Africans? They really havent been in contact with a civilized country for some time; really since the 1500's and the Arabs/muslims in Eastern and Western Africa.
Norsemaiden said:The question was this. You are the first person in the world that I have ever heard suggest that evolution happens by means of species mixing. If it were true that this were the mechanism for evolution, then rather than start with few species which separate over time into further species (each adapting to its own environmental niche) - which is the method of evolution that all scientists agree happens - rather than this ARE YOU SAYING that there would have been many species originally and evolution is all about the many merging together and reducing in number?????!
If this is wrongly presumed on my part, please explain how the Earth ended up having so many species while at the same time evolution happens by species mixing (according to you).
And try to calm down. It's not worth getting stressed about. It's only a debate!
the alumnus said:i don't understand why you would think i am not calm, you use far more capitals that i...
no, you misunderstand. i did not mean to suggest that mixing of species is the only mechanism for evolution. but it is one way that it happens, and is easily observable. rather, i was try to disprove the statement "Undoubtedly there is far more homogeneity amongst individuals of a wild species of animal than there is in a race of humans. Wild animals speciate (seperate themselves into further different species) that is how evolution happens. Only domesticated animals interbreed". i was also demonstrating the values of outcrossing, which not only occurs in the wild, but occasionally can be beneficial.

Providing the strongest evidence yet that humans are still evolving, researchers have detected some 700 regions of the human genome where genes appear to have been reshaped by natural selection, a principal force of evolution, within the last 5,000 to 15,000 years.
The genes that show this evolutionary change include some responsible for the senses of taste and smell, digestion, bone structure, skin color and brain function.
Many of these instances of selection may reflect the pressures that came to bear as people abandoned their hunting and gathering way of life for settlement and agriculture, a transition well under way in Europe and East Asia some 5,000 years ago.
Under natural selection, beneficial genes become more common in a population as their owners have more progeny.
Three populations were studied, Africans, East Asians and Europeans. In each, a mostly different set of genes had been favored by natural selection. The selected genes, which affect skin color, hair texture and bone structure, may underlie the present-day differences in racial appearance.
The study of selected genes may help reconstruct many crucial events in the human past. It may also help physical anthropologists explain why people over the world have such a variety of distinctive appearances, even though their genes are on the whole similar, said Dr. Spencer Wells, director of the Genographic Project of the National Geographic Society.
The finding adds substantially to the evidence that human evolution did not grind to a halt in the distant past, as is tacitly assumed by many social scientists. Even evolutionary psychologists, who interpret human behavior in terms of what the brain evolved to do, hold that the work of natural selection in shaping the human mind was completed in the pre-agricultural past, more than 10,000 years ago.
"There is ample evidence that selection has been a major driving point in our evolution during the last 10,000 years, and there is no reason to suppose that it has stopped," said Jonathan Pritchard, a population geneticist at the University of Chicago who headed the study.
Dr. Pritchard and his colleagues, Benjamin Voight, Sridhar Kudaravalli and Xiaoquan Wen, report their findings in today's issue of PLOS-Biology.
Their data is based on DNA changes in three populations gathered by the HapMap project, which built on the decoding of the human genome in 2003. The data, though collected to help identify variant genes that contribute to disease, also give evidence of evolutionary change.
The fingerprints of natural selection in DNA are hard to recognize. Just a handful of recently selected genes have previously been identified, like those that confer resistance to malaria or the ability to digest lactose in adulthood, an adaptation common in Northern Europeans whose ancestors thrived on cattle milk.
But the authors of the HapMap study released last October found many other regions where selection seemed to have occurred, as did an analysis published in December by Robert K. Moysis of the University of California, Irvine.
Dr. Pritchard's scan of the human genome differs from the previous two because he has developed a statistical test to identify just genes that have started to spread through populations in recent millennia and have not yet become universal, as many advantageous genes eventually do.
The selected genes he has detected fall into a handful of functional categories, as might be expected if people were adapting to specific changes in their environment. Some are genes involved in digesting particular foods like the lactose-digesting gene common in Europeans. Some are genes that mediate taste and smell as well as detoxify plant poisons, perhaps signaling a shift in diet from wild foods to domesticated plants and animals.
Dr. Pritchard estimates that the average point at which the selected genes started to become more common under the pressure of natural selection is 10,800 years ago in the African population and 6,600 years ago in the Asian and European populations.
Dr. Richard G. Klein, a paleoanthropologist at Stanford, said that it was hard to correlate the specific gene changes in the three populations with events in the archaeological record, but that the timing and nature of the changes in the East Asians and Europeans seemed compatible with the shift to agriculture. Rice farming became widespread in China 6,000 to 7,000 years ago, and agriculture reached Europe from the Near East around the same time.
Skeletons similar in form to modern Chinese are hard to find before that period, Dr. Klein said, and there are few European skeletons older than 10,000 years that look like modern Europeans.
That suggests that a change in bone structure occurred in the two populations, perhaps in connection with the shift to agriculture. Dr. Pritchard's team found that several genes associated with embryonic development of the bones had been under selection in East Asians and Europeans, and these could be another sign of the forager-to-farmer transition, Dr. Klein said. . .
