The Tarahumaras: An Endangered Species : Mexico Culture & Arts Shep Lenchek Never conquered by the Aztecs and despite being defeated by Mexican armies, the Tarahumaras still consider themselves an independant nation. So strong is this conviction that in the Fifties they more than once took complaints directly to the United Nations. Perhaps the purest and most unmixed of any Indian tribe in Mexico, so little is known about them that their true name "Raramuri" was corrupted to "Tarahumara" by white men and never corrected. Most of the world knows them only as long distance runners. However, this running ability is only one facet of their life style. Psychologists suggest that over the centuries this value system has actually caused physiological changes in their brain that preclude speaking anything but the truth. Luis G. God is both Father and Mother. Today the "People" (the translation of the name Raramuri) have been driven into the highest reaches of the Sierra Tarahumara, in the State of Chihuahua.
Chinese fossils shed light on evolutionary origin of animals from single-cell ancestors Evidence of the single-celled ancestors of animals, dating from the interval in Earth's history just before multicellular animals appeared, has been discovered in 570 million-year-old rocks from South China by researchers from the University of Bristol, the Swedish Museum of Natural History, the Paul Scherrer Institut and the Chinese Academy of Geological Sciences. All life evolved from a single-celled universal common ancestor, and at various times in Earth history, single-celled organisms threw their lot in with each other to become larger and multicellular, resulting, for instance, in the riotous diversity of animals. However, fossil evidence of these major evolutionary transitions is extremely rare. The researchers studied the microscopic fossils using high energy X-rays at the Swiss Light Source in Switzerland, revealing the organisation of the cells within their protective cyst walls.

The Flynn Effect Originally prepared by: Charles Graham (fall 2001)Revised: Jonathan Plucker (fall 2002) The Flynn Effect deals with the issue of how the general IQ scores of a population change over time. Outline (back to top) Introduction How large are the IQ gains? Where is the IQ test data from? What are possible causes for the Flynn Effect? Why must IQ tests be constantly restandardized? Who has written about the Flynn Effect? Introduction (back to outline) In his study of IQ tests scores for different populations over the past sixty years, James R. How large are the IQ gains? Research shows that IQ gains have been mixed for different countries. Fluid Intelligence Crystallized Intelligence Where is the IQ test data from? What are possible causes for the Flynn Effect?

Peabody Museum New research may show that Neandertals did not go extinct By Philip Guelpa 27 December 2011 The recently reported results of genetic research comparing samples of fossil Neanderthal DNA with that of modern populations around the world appear to indicate that modern humans outside of Africa derive some portion of their genetic material from Neanderthals. This finding, if supported by further research, has important implications, not only in answering the longstanding question of what happened to the Neanderthals, but more importantly for our understanding of the relative weight of cultural versus biological adaptation in human evolution. Since the discovery of human-like fossils in the Neander Valley of German in the mid-19th century, anthropologists and others have debated the question of how closely Neanderthals, as this fossil group was named, were related to modern humans. The question soon became entangled in the larger issue of biological evolution in general after the publication of Darwin’s On the Origin of Species. References
Researchers uncover 8,000 years of human history hidden in the Middle East Which would be interesting, seeing as, when interpreted literally, the Bible also claims that the universe was created between 6000-8000 years ago. Which is problematic, to say the least. EDIT: Not to mention the mental gymnastics required to reconcile the (presumably) carbon dating of the earliest Mesopotamian settlements to 8000 years ago and the fact that that same dating methods go on to describe artifacts and fossils that are up to 40 000 years old. As I recall, Asimov hypothesized that the age of creation used in the Bible is actually linked to the point at which we (or rather Near Eastern peoples) began recording history in the form of writing. Not sure how strong his evidence was but it sounds reasonable intuitively. That's always been the same assumption that I have made. Population growth: Ban homosexuality.

Human Evolution & Archaeology The mystery of the labyrinth by Mirko Elviro This symbol represents a real mystery: in fact it appears in very different places and times. Its meaning is a mystery. Some researchers believe that it is a "ritual course", confining it to the religious-mystic field.

On Pangaea, latitude and rain dictated where species lived PROVIDENCE, R.I. [Brown University] — Aggregating nearly the entire landmass of Earth, Pangaea was a continent the likes our planet has not seen for the last 200 million years. Its size meant there was a lot of space for animals to roam, for there were few geographical barriers, such as mountains or ice caps, to contain them. Yet, strangely, animals confined themselves. Studying a transect of Pangaea stretching from about three degrees south to 26 degrees north (a long swath in the center of the continent covering tropical and semiarid temperate zones), a team of scientists led by Jessica Whiteside at Brown University has determined that reptiles, represented by a species called procolophonids, lived in one area, while mammals, represented by a precursor species called traversodont cynodonts, lived in another. "We're answering a question that goes back to Darwin's time," said Whiteside, assistant professor of geological sciences at Brown, who studies ancient climates.
Comics & Anthropology « Public Space, Information Accessibility, Technology, and Diversity at Oslo University College This comic book, in both its form and content, breaks with the traditional way of presenting ethnography. Traditionally, anthropology has been a written enterprise. Writing is perceived as the most scientific form of representation of social life. However, other forms of representation exist—not only in other disciplines (like art) but also within anthropology and social sciences. Anthropological findings have been presented in such forms as photography, film, and material exhibitions. Visual anthropology is mostly concerned with the examination and production of ethnographic film and photography in which the product shows signs of a documentary perspective and real individuals participate in those productions. This comic book is a collection of ethnographic situations. While working on this collection, various storylines, narrative arcs, drawings, and so forth, we were faced with a series of esthetic, philosophical, and ethical choices. Like this: Like Loading...
It Takes Teamwork: How Endosymbiosis Changed Life on Earth It Takes Teamwork: How Endosymbiosis Changed Life on Earthby the Understanding Evolution team In 1966, microbiologist Kwang Jeon was studying single-celled organisms called amoebae, when his amoebae communities were struck by an unexpected plague: a bacterial infection. Literally thousands of the tiny invaders — named x-bacteria by Jeon — squeezed inside each amoeba cell, causing the cell to become dangerously sick. Only a few amoebae survived the epidemic. However, several months later, the few surviving amoebae and their descendents seemed to be unexpectedly healthy. Had the amoebae finally managed to fight off the x-bacterial infection?
Race I like race. I know it sounds odd, even politically incorrect. But I really enjoy the differences among people around the world. One aspect of this is all our different cultures. But another is all our different physical types. I get a kick out of reading and thinking about how we got to look the way we look, where our characteristics came from, why they are there at all. The races are definitely not "subspecies." Because the concept of race has been confused so thoroughly with our terrible history of racism, many avoid the term altogether. Skin Speaking of the "red" man, the "white" man, and the "black" man, skin color is perhaps the first characteristic we think of when we think of race. Skin, hair, and eye color are due to relative amounts of melanin. The experts are pretty much in agreement about how the varieties of skin color came about. Once people were out of Africa, there was a lot more variation in levels of sunlight. Hair Eyes Blood Genes Another approach uses the term lineages.
