Study Detects Recent Instance of Human Evolution

The New York Times is running a Sunday article regarding new evidence about 'recent' human evolution. A research team at the University of Maryland has done some work looking at the rise of lactose tolerance in the human populations of Africa. From the article: "The principal mutation, found among Nilo-Saharan-speaking ethnic groups of Kenya and Tanzania, arose 2,700 to 6,800 years ago, according to genetic estimates, Dr. Tishkoff's group is to report in the journal Nature Genetics on Monday. This fits well with archaeological evidence suggesting that pastoral peoples from the north reached northern Kenya about 4,500 years ago and southern Kenya and Tanzania 3,300 years ago ... Genetic evidence shows that the mutations conferred an enormous selective advantage on their owners, enabling them to leave almost 10 times as many descendants as people without them. The mutations have created 'one of the strongest genetic signatures of natural selection yet reported in humans,' the researchers write. "

    Unfortunately this will prove to be an evolutionary dead end, as these genes will never be passed on.

    Why does natural selection favor lactase?

    Because you're far more likely to survive the couple of millenia between domesticating cattle and making your first gun if you can tolerate lactose.

  6. A dangerous and incorrect fallacy by Dobeln · · Score: 3, Funny

    I believe this line of reasoning to be mistaken to some degree - evolution of man and squirrel alike indeed continued apace until ~approx 100 000 years ago, when modern man first left Africa and the laws of evolution ceased to apply to humans, due to the plasticity of spandrels. Hence, positing evolution of humanity is incorrect in timespans extending much further back than a mere 6000 years. After this no evolution whatsoever has taken place among humans, and therefore the article referenced above must be incorrect.

    It is hard to determine if this study and many other recent similar ones implying recent evolution in humans are driven by mere ignorance or if more sinister motives are at work. The author referenced here, one Nicholas Wade, is notable for engaging in ideologically dubious activities, such as his recent book "Before the Dawn". He must be watched closely, or his dangerous line of thinking might be allowed to spread among the easily manipulated masses.

    According to "The Restaurant at the End of the Universe", Noah was the captain of the B-Ark, which contained the TV salesmen, hairdressers, creationists; plus the DNA samples of each of the animals (to fit them all in the limited cubic-cubits available.) Unfortunately, before the C-Ark (containing the refrigeration mechanics etc.) arrived, the samples had begun to thaw; the scientists (on the A-Ark) did their best, but many mutations had occurred - leading to such monstrosities as the poodle and chiahuaia.
