Culture out of Africa next chapter The Contradictory Diversity of Anthropoid Societies Evolutionary equilibrium means that a strategy has to be optimal to any changes either sex might inflict, or any defection from the game theoretic equilibrium the situation might present. In the context of sex this means that societies need to reflect the complementary interplay between the vastly differing reproductive investments females and males make, the one massive and forthright, and the other opportunistic and competitive. Diverse ape societies derive their complexity and viability through responding to this sexual interplay, without the extensive capacity humans have for imposing ‘artificial’ cultural structures upon it. The relative clumping or diffuse nature of plant foods, determine, through the female foraging distribution, and the opportunities it provides males, whether ape species are monogamous very dispersed females , form harems clumping sufficient for one male to guard several females – e. Pan troglodite, and the bonobo or pygmy chimpanzee, Pan paniscus. In turn these reproductive patterns determine the shifting hierarchies and coalitions of social structure. The most promiscuous ape societies are the most complex and versatile. Monogamous gibbons lead a solitary and relatively sterile existence in widely spaced territories with little social interaction. For Gorillas there is a little more dynamic movement. Largely affairs are dominated by a silver back who retains dominance over his harem while struggling endlessly against being toppled and his females robbed by a more powerful male.

Once upon a time, 4, to 8, years after humanity invented agriculture, something very strange happened to human reproduction. Across the globe, for every 17 women who were reproducing, passing on genes that are still around today—only one man did the same.
This suggests that the Paleoindian migration could have spread more quickly along the Pacific coastline, proceeding south, and that populations that settled along that route could have then begun migrations eastward into the continent. The Pedra Furada sites in Brazil include a collection of rock shelters, which were used for thousands of years by diverse human populations.
The first excavations yielded artifacts with carbon dates of 48, to 32, years BP. Repeated analyses have confirmed this dating, carrying the range of dates up to 60, BP. In , worked stone tools were found at Topper in South Carolina that have been dated by radiocarbon techniques possibly to 50, years ago. The Tlapacoya site in Mexico is located along the base of a volcanic remnant hill on the shore of the former Lake Chalco.
Seventeen excavations along the base of Tlapacoya Hill between and uncovered piles of disarticulated bones of bear and deer that appeared to have been butchered, plus 2, flakes and blades presumably from the butchering activities, plus one unfluted spear point. All were found in the same stratum containing three circular hearths filled with charcoal and ash. Bones of many other animal species were also present, including horses and migratory waterfowl. Two uncalibrated radiocarbon dates on carbon from the hearths came in around 24, and 22, years ago.
The hydration results were published in a seminal article that deals with the evidence for pre-Clovis habitation of Mexico. The study team suggest that finding this genetic evidence so far inland shows that “current distribution of genetic markers are not necessarily indicative of the movement or distribution of peoples in the past. Further testing found that Anzick-1 was most closely related to Native American populations see below.
Solutrean hypothesis The controversial Solutrean hypothesis proposed in by Smithsonian archaeologist Dennis Stanford and colleague Bruce Bradley Stanford and Bradley , suggests that the Clovis people could have inherited technology from the Solutrean people who lived in southern Europe 21, —15, years ago, and who created the first Stone Age artwork in present-day southern France.

The couple who met at Berklee College of Music in Boston and have been dating for 5 years after writing couple songs together decided to start their own group. Now the full Karmin interview, hope you enjoy it. Hi Guys, Thanks for doing this, how are you both doing? A bit bloated…but besides that, fantastic. Can you give us some background information about yourselves so the YHP audience can get to know you better? We make YouTube videos of our original songs and also cover popular songs.
We sat down with them to get the scoop on the inspiration for the album and how they manage to eat clean even while traveling. Eggs in the morning, a massive salad for lunch and a perfectly cooked salmon for dinner, all gluten and bread free. How do you two start your day? I try to drink two big glasses of water before I do anything else. Then, its been eggs with organic chicken apple sausage and green tea. I start with coffee Nespresso and Nick cooks me eggs and gluten-free toast.

Most ancient pottery Man the hunter theories are prone to stress male violence and treat women as mere possessions and tradeable items. While they do fit well with our cultural paradigm of male dominance, they do not well-explain the origin of intelligence p 53 , nor do they fit well with what we know of so-called primal cultures, where women bring in the majority of the diet by gathering p , making them more autonomous as child-rearers than the theory would allow.
As a natural successor of the ‘killer-ape’ theory it gives a pessimistic view of humanity’s violence and viability. The counterpoised matriarchal origin theory is the ‘mother-right’ proposed by Johan Jakob Bachofen R31 – an evolutionary ‘advance’ in which an intervening stage of matriarchy led society out of barbarism into modern patriarchy, which he deemed the triumph of superior political and religious thought and organization, despite advocating the incorporation of the ‘feminine principle’ of nurturance and altruism in modern society.
The Swiss philologist proposed an era of ‘unregulated hetaerism’ in which women were sexually degraded and defenseless, followed by an ‘Amazon’ revolt that inaugurated an era of matriarchy. In this stage, women created marriage to tame the male. This supposedly still-animalistic and ‘backward’ era was superseded by a ‘higher’ stage of human development: He never used the term matriarchy but ‘mutterricht’ and gynecocracy, for ‘rule by women’.
Following him Engels R , used the term mother-right ‘to describe matrilineal kinship relations, in which the property of men did not pass to their children, but to their sisters’ children’. Both also accepted a progression from group marriage to monogamous marriage.

The Clovis culture is a prehistoric Paleo-Indian culture, named for distinct stone tools found in close association with Pleistocene fauna at Blackwater Locality No. 1 near Clovis, New Mexico, in the s and appears around 11,–11, uncalibrated radiocarbon years before present at the end of the last glacial period, and is characterized by the manufacture of “Clovis points.
Cohanim[ edit ] Nephrologist Dr. Karl Skorecki decided to analyze the Cohanim to see if they were the descendants of one man, in which case they should have a set of common genetic markers. To test this hypothesis, he contacted Dr. Michael Hammer of the University of Arizona , a researcher in molecular genetics and a pioneer in research on chromosomes. A set of special markers called Cohen Modal Haplotype or CMH was defined as one which is more likely to be present in the Cohanim, defined as contemporary Jews named Cohen or a derivative, and it was proposed that this results from a common descent from the ancient priestly lineage than from the Jewish population in general.
But, subsequent studies  showed that the number of genetic markers used and the number of samples of people saying Cohen were not big enough. The last study, conducted in by Hammer and Behar et al. Among these first 5 haplogroups, J-P58 or J1E accounts for Hammer and Behar have redefined an extended CMH haplotype as determined by a set of 12 markers and having as “background” haplogroup determining the most important lines J1E

Fossil and genetic evidence on modern human origins and dispersals Author links open overlay panel HugoReyes-Centenoab Show more https: Despite this consensus, several questions remain with regard to the mode and timing of dispersal out of the continent. Competing models differ primarily by the number of dispersals, their geographic route, and the extent to which expanding modern humans interacted with other hominins.
Central in this debate is whether Southeast Asia was occupied significantly earlier than other parts of Eurasia and, if so, whether the population ancestral to extant Southeast Asians was notably different from the ancestors of extant Eurasians.

History[ edit ] — Original terminal[ edit ] After the opening of the International Arrivals Building in , the major US airlines each built their own terminals at the airport. Saarinen planned the appearance of the building from a purely formal perspective mainly to exploit market opportunities. Thus, the TWA Terminal represents an entirely different approach than the thin concrete shells constructed at the same time.
The terminal was built to span a space with a minimum of material. Saarinen, who was known as an indefatigable architect, indicated to his client that he needed more time, then took another year to resolve the design. View of TWA Flight Center A footbridge spans the terminal Original concourse We wanted passengers passing through the building to experience a fully-designed environment in which each part arises from another and everything belongs to the same formal world.
Eero Saarinen  The terminal was one of the first with enclosed passenger jetways ,  closed circuit television , a central public address system, baggage carousels ,  electronic schedule board and baggage scales, and the satellite clustering of gates away from the main terminal.
