suspected to be related to brain function show very different distributions in different ethnic groups, and show signs of having been subject to strong selection fairly recently in human history. Of course, one cannot directly conclude anything about effects on intelligence, but the implication is pretty strong that there are correlations between distributions of genes with phenotypical consequences beyond superficial traits like skin or hair color, and traditional conceptions of ethnicity. This was already known for genes related to certain diseases like Tay-Sachs or sickle cell anemia. For related posts, see here and here. <br /> <br />NYTimes: Two genes involved in determining the size of the human brain have undergone substantial evolution in the last 60,000 years, researchers say, suggesting that the brain is still undergoing rapid evolution. <br /> <br /> The discovery adds further weight to the view that human evolution is still a work in progress, since previous instances of recent genetic change have come to light in genes that defend against disease and confer the ability to digest milk in adulthood. <br /> <br /> The new finding, reported by Bruce T. Lahn of the University of Chicago and colleagues in the journal Science, could raise controversy because of the genes' role in determining brain size. <br />New versions of the genes, or alleles, as geneticists call them, appear to have spread because they enhanced the brain's function in some way, the report suggests, and they are more common in some populations than others. <br /> <br /> ...They report that with microcephalin, a new allele arose about 37,000 years ago, although it could have appeared as early as 60,000 or as late as 14,000 years ago. Some 70 percent or more of people in most European and East Asian populations carry this allele of the gene, as do 100 percent of those in three South American Indian populations, but the allele is much rarer in most sub-Saharan Africans. <br /> <br /> With the other gene, ASPM, a new allele emerged some time between 14,100 and 500 years ago, the researchers favoring a mid-way date of 5,800 years. The allele has attained a frequency of about 50 percent in populations of the Middle East and Europe, is less common in East Asia, and found at low frequency in some sub-Saharan Africa peoples. <br /> <br /> More coverage here, including comments like the following: <br />What I love about this article is that we're starting to get to the bottom of the seemingly infinite regress of lies and obfuscations. <br /> <br /> Note that <br /> 1) they can't call Lahn a racist (he's a Chinese ancestry HHMI investigator publishing in Science, for god's sake) <br /> 2) they can't say the genes weren't selected <br /> 3) They can't say all populations have equal frequencies of these alleles <br /> 4) ...and they can't even say that there is even significant overlap between all populations on this locus (a la lewontin's 85/15 fallacy) <br /> <br /> So those are four biggies gone at the outset. As Lahn has (wisely) separated the psychometric arguments -- for now -- they also can't demagogue IQ. So that's another one down. <br /> <br /> Goldstein threw up drift, but it was already demolished -- unlike baseless mumbling about spandrels, it is actually a testable hypothesis and makes quantitative predictions (e.g. linkage disequilibrium varies for things boosted by drift vs. by selection). So it was tested and rejected, as it was in the Ashkenazi Cochran/Harpending paper. Next? <br /> <br /> Next up they say that maybe *this* ASPM variant had some anomalous non-brain related function, or that different populations might not all have the same frequency of this allele, but that they have different complements of alleles that all lead to exactly the same distribution of ability. <br /><a

<br /> <br />09.08.2012 <br /> <br />Co najmniej trzy gatunki człowiekowatych koegzystowały w Afryce około 2 mln lat temu - informuje BBC. <br /> <br />Potwierdza to, że ewolucja naszego gatunku nie była liniowa - od małpy do Homo sapiens. Było wiele ślepych uliczek. Przetrwały najlepiej adaptujące się hominidy - wynika z najnowszych odkryć archeologów w Kenii. <br /> <br /> <br />W północnej Kenii archeolodzy odkryli trzy fragmenty ludzkich szczątków, datowanych na okres między 1,78 i 1,95 miliona lat temu. <br /> <br />Znalezione pozostałości praczłowieka to kości twarzy i szczęki z zębami. Wyniki badań, opublikowane w magazynie "Nature", są sensacyjne: kenijskie odkrycie wskazuje na to, że w tym samym czasie w Afryce żyły obok siebie trzy różne gatunki ludzi - podkreśla BBC i dodaje, że kenijskie znalezisko jest silnym dowodem wspierającym tezę, że ewolucja gatunku ludzkiego nie przebiegała liniowo - od małpy do Homo sapiens. <br />Po drodze było wiele ślepych uliczek. <br /> <br />Mówił też o tym niedawno w TOK FM dr Marcin Ryszkiewicz z PAN. "Wszyscy jesteśmy... Azjatami? Bardziej niż Afrykanami" - czytaj >>> <br /> <br />Tajemnica Homo rudolfensis <br />W 1972 r. znaleziono tajemniczą czaszkę, którą teraz zakwalifikowano jako należącą do nowego, nieznanego gatunku człowieka - <span style="font-weight: bold">Homo rudolfensis.</span> Rozmiary czaszki wskazują na wyjątkowo duży mózg, a twarz człowieka, do którego należała, musiała być pociągła i płaska. Jednak przez 40 lat jedynym dowodem na istnienie Homo rudolfensis była tylko ta czaszka. <br />Naukowcy nie mogli potwierdzić, czy mają do czynienia z nowym gatunkiem, czy z wyjątkowym osobnikiem znanych gatunków. <br /> <br />Kenijskie odkrycie wzmacnia tezę o odrębności Homo rudolfensis jako odrębnego gatunku człowieka. Od około 50 lat archeolodzy wiedzą, że w Afryce najprawdopodobniej koegzystowały ze sobą dwa gatunki praludzi - <span style="font-weight: bold">Homo erectus i Homo habilis</span>. <br /> <br />Teraz okazało się, że najprawdopodobniej w tym samym czasie na afrykańskim kontynencie żył jeszcze trzeci gatunek. Według szefowej wykopalisk dr Meave Leakey z Instytutu Jeziora Turkana (Rudolfa), nowe znalezisko oznacza, że wczesne stadia ewolucji człowieka charakteryzowały się ogromną różnorodnością. <br /> <br />"Tak jakby natura rozwijała prototypy człowieka" <br /> <br />- Nasza przeszłość była zróżnicowana. Nasz gatunek ewoluował tak samo jak inne. Nie było w naszej ewolucji nic niezwykłego - do chwili, gdy zaczęliśmy wyrabiać narzędzia z kamienia - powiedziała dla BBC. <br /> <br />To oznacza po prostu, że człowiek podlegał takim samym prawom jak inne gatunki - jeśli wykształcona w toku ewolucji cecha pozwalała łatwiej przeżyć w środowisku, utrwalała się. <br /> <br />I odwrotnie - jeśli nowa cecha sprawiała, że dany gatunek był słabszy, ginął. <br /> <br />Jak powiedział BBC prof. Chris Stinger z Muzeum Historii Naturalnej w Londynie, dowody z kenijskich wykopalisk coraz wyraźniej wskazują na to, że ludzka ewolucja podlegała tym samym prawom. <br /> <br />I przebiegała w różny sposób, zależnie od miejsc, gdzie żyły poszczególne grupy i osobniki. <br /> <br />- To wygląda tak, jakby natura rozwijała różne prototypy ludzkie z różnymi cechami, a ostatecznie tylko jeden z nich, nasz przodek, osiągnął sukces - stwierdził prof. Stringer. </td> </tr></table><span class="postbody"> <br /><a href="http://io9.com/5932362/a-new-human-species-has-been-identified-in-africa" target="_blank">http://io9.com/5932362/a-new-human-species-has-been-identified-in-africa</a> <br /> <br />Cos mi przyszlo do glowy.........

Pagel: "Fur is not an effective insulator in water, and so the [aquatic-ape] theory asserts that we evolved to lose our fur, replacing it, as other aquatic mammals have..." <br /> <br />It seems that arctic seals, sea lions, polar bears and sub-arctic otters and beavers may disagree with this theory that having fur is a disadvantage in water. <br /> <br />Seals, of course, abound in both arctic and temperate waters, and have long been prized by humans for their furs. So the idea that people lost their fur to be better food gatherers in shallow seas seems insubstantial. <br /> <br />The heat management, insect control, and sexual attraction theories also seem lightly grounded in that of the thousands of other species of mammals that lived in the same environs as early humans, none developed the same adaptation. <br /> <br />The question is adaptation to what? Here are some factors to consider: most of the time that humans have existed has been during ice ages; big brains have to be fed by enormous intakes of protein; advancing ice concentrates game. <br /> <br />As advancing ice pushed food animals southward that our hominid ancestors depended on for the high protein their big brains needed, these prey were likely concentrated in a band just below the ice. So the big brains with the best hunting tools tended to stay just ahead of the ice in the best hunting grounds, therefore in a cold climate. To fight the cold, they wore the furs of their kills to better retain their own body heat. In parallel evolutions, their manual dexterity, abstract imagination, and cooperative living advanced to enable them to design and make effective clothing from animal skins. From wearing animal skins, they lost most of their own fur and evolved the perspiration system for better body heat management. Thus, wearing animal skins greatly improved the hominids' ability to adapt to seasonal climates and to extend range. Eventually the greater intelligence and dexterity required to make clothing enabled farming and its more reliable sources of protein demanded by even bigger brains. <br /> <br />So here we are. <br /> <br />Solving the mystery about why Neanderthals became extinct while our ancestors survived about 30,000 years ago may hinge on discovering whether or not Neanderthals wore animal furs as clothing and had thereby lost their own fur. <br /> <br />It has been reported that Neanderthals had somewhat larger brains than homo sapiens, but that the cultural evidence they left behind indicates that their minds lacked the imagination of homo sapiens - an imagination that could have become crucial for adaptive survival in a sudden change of environmental circumstances. <br />Imagination is a prerequisite for designing and making even crude types of clothing, especially clothing for a cold environment. <br /> <br />And once early humans became dependent on clothing, the more natural selection would have favored the development of greater imagination in order to create more durable, more adaptive clothing that would have given them a greater edge for survival. <br /> <br />Dependence on clothing would have caused a parallel dependence on housing -and of course fire - to better protect us against the bitter night and vicious weather that even the wearing of skins couldn't withstand. And the abstract imagination developed for making clothing could easily be applied to making shelter. <br /> <br />It was an imagination Neanderthals apparently lacked, though they may have had fur instead. <br /> <br /></td> </tr></table><span class="postbody"> <br /> <a href="http://www.scientificamerican.com/article.cfm?id=latest-theory-human-body-hair" target="_blank">http://www.scientificamerican.com/article.cfm?id=latest-theory-human-body-hair</a></span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/subSilver/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> <tr> <td width="22%" align="left" valign="top" class="row1"><span class="name"><a name=""></a><b>Pamela</b></span></td> <td class="row1" height="28" valign="top"><table width="100%" border="0" cellspacing="0" cellpadding="0"> <tr> <td width="100%"><img src="http://picsrv.fora.pl/subSilver/images/icon_minipost.gif" width="12" height="9" alt="Post" title="Post" border="0" /><span class="postdetails">Wysłany: Śro 10:36, 17 Paź 2012<span class="gen"> </span> Temat postu: </span></td> </tr> <tr> <td colspan="2"><hr /></td> </tr> <tr> <td colspan="2"><span class="postbody"></span><table width="90%" cellspacing="1" cellpadding="3" border="0" align="center"><tr> <td><span class="genmed"><b>H.
