    Finding Pre-Clovis Humans in the Oregon High Desert An interview with Dennis Jenkins See Interview About Dennis Jenkins In this interview, conducted at Paisley Five Mile Point Caves on June 13, 2007, by Rick Pettigrew of ALI, Dr. Dennis Jenkins describes the remarkable discovery of human DNA in coprolites dated between 14,000 and 15,000 calibrated years ago. This evidence, reported in the 3 April 2008, issue of the journal Science, strongly supports the proposition that human migrants to North America arrived at least 1000 years before the widespread Clovis complex appeared. The data also support the conclusion that the first...

    While diving in the harbor of a small island in Indonesia recently, husband and wife Buck and Fitrie Randolph, with dive guide Toby Fadirsyair, found a strange fish and took some pictures. The oddball creature looks like an anglerfish, but different. Its eyes, unlike those of nearly all fish, point forward and may allow the fish to gauge depth the way humans do. The flat fish has tan- and peach-colored stripes and rippling folds of skin that obscure its fins. About the size of a human fist, it is soft and pliable enough to slip into narrow crevices of coral...

    Humans Have More Distinctive Hearing Than Animals, Study Shows ScienceDaily (Apr. 2, 2008) — Do humans hear better than animals? It is known that various species of land and water-based living creatures are capable of hearing some lower and higher frequencies than humans are capable of detecting. However, scientists from the Hebrew University of Jerusalem and elsewhere have now for the first time demonstrated how the reactions of single neurons give humans the capability of detecting fine differences in frequencies better than animals. They did this by utilizing a technique for recording the activity of single neurons in the auditory...

    Upright Walking Began 6 Million Years Ago Newswise — A shape comparison of the most complete fossil femur (thigh bone) of one of the earliest known pre-humans, or hominins, with the femora of living apes, modern humans and other fossils, indicates the earliest form of bipedalism occurred at least six million years ago and persisted for at least four million years. William Jungers, Ph.D., of Stony Brook University, and Brian Richmond, Ph.D., of George Washington University, say their finding indicates that the fossil belongs to very early human ancestors, and that upright walking is one of the first human characteristics...

    Out of Africa, Not Once But Twice Jennifer Viegas, Discovery News Out of Africa March 14, 2008 -- Modern humans are known to have left Africa in a wave of migration around 50,000 years ago, but another, smaller group -- possibly a different subspecies -- left the continent 50,000 years earlier, suggests a new study. While all humans today are related to the second "out of Africa" group, it's likely that some populations native to Israel, Jordan, Lebanon, Syria, Australia, New Zealand and Indonesia retain genetic vestiges of the earlier migrants, according to the paper's author, Michael Schillaci.

    Gorillas have been caught on camera for the first time performing face-to-face intercourse. Humans and bonobos were the only primates thought to mate in this manner. And while researchers have observed wild gorillas engaged in such an act, it had never been photographed. "Our current knowledge of wild western gorillas is very limited, and this report provides information on various aspects of their sexual behavior," said Thomas Breuer of the Max Planck Institute for Evolutionary Anthropology. "It is fascinating to see similarities between gorilla and human sexual behavior demonstrated by our observation."

    Lice from mummies provide clues to ancient migrations By John Noble Wilford Published: February 6, 2008 When two pre-Columbian individuals died 1,000 years ago, arid conditions in the region of what is now Peru naturally mummified their bodies, down to the head lice in their long, braided hair. This was all scientists needed, they reported Wednesday, to extract well-preserved louse DNA and establish that the parasites had accompanied their human hosts in the original peopling of the Americas, probably as early as 15,000 years ago. The DNA matched that of the most common type of louse known to exist worldwide,...

    In the study of human origins, paleoanthropology stares in frustration back to a dark age from three million to less than two million years ago. The missing mass in this case is the unfound fossils to document just when and under what circumstances our own genus Homo emerged. The origin of Homo is one of the most intriguing and intractable mysteries in human evolution. New findings only remind scientists that answers to so many of their questions about early Homo probably lie buried in the million-year dark age. It is known that primitive hominids — human ancestors and their close...

    LONDON - Neanderthals probably fell victim to taller and superior Cro-Magnons rather than catastrophic climate change, researchers said on Wednesday. Using a new method to calibrate carbon-14 dating, the international team found the last Neanderthals died at least 3,000 years before a major change in temperatures occurred. This suggests either modern humans or a combination of humans and less severe climate change caused the species' demise some 30,000 years ago, said Chronis Tzedakis, a paleoecologist at the University of Leeds, who led the study published in the journal Nature.....

    WASHINGTON - Why did humans evolve to walk upright? Perhaps because it's just plain easier. Make that "energetically less costly," in science-speak, and you have the conclusion of researchers who are proposing a likely reason for our modern gait. Bipedalism — walking on two feet — is one of the defining characteristics of being human, and scientists have debated for years how it came about. In the latest attempt to find an explanation, researchers trained five chimpanzees to walk on a treadmill while wearing masks that allowed measurement of their oxygen consumption.

    Stanford University Date: February 25, 2007 Why Do Humans And Primates Get More Stress-related Diseases Than Other Animals? Science Daily — Why do humans and their primate cousins get more stress-related diseases than any other member of the animal kingdom? The answer, says Stanford University neuroscientist Robert Sapolsky, is that people, apes and monkeys are highly intelligent, social creatures with far too much spare time on their hands. "Primates are super smart and organized just enough to devote their free time to being miserable to each other and stressing each other out," he said. "But if you get chronically, psychosocially...

    Spread Of Modern Humans Occurred Later Than Previously Thought, Profs Say Thursday, January 11, 2007 The spread of modern humans out of Africa occurred 40,000 to 50,000 years later than previously thought, according to researchers including one Texas A&M University anthropologist. Ted Goebel, associate director of the Center for the Study of the First Americans at Texas A&M, is the author of the paper titled “The Missing Years for Modern Humans” that appears in the Jan. 12 (Friday) issue of Science. Goebel’s paper is one of three published in the current issue of Science dealing with the origins and dispersals...

    Going Under Down Under: Early people at fault in Australian extinctions Sid Perkins A lengthy, newly compiled fossil record of Australian mammals bolsters the notion that humanity's arrival on the island continent led to the extinction of many large creatures there. Archaeological evidence suggests that people arrived in northern and western Australia about 50,000 years ago (SN: 3/15/03, p. 173: Available to subscribers at http://www.sciencenews.org/articles/20030315/note10.asp). By 5,000 years later, about 90 percent of the continent's mammals larger than a house cat had gone extinct, says Gavin J. Prideaux, a paleontologist at the Western Australian Museum in Perth. Casualties of that...

    NEW DELHI, DECEMBER 30: Ten days into the New Year, India will launch a space capsule. The 50-kg capsule, which will be brought back after 15-30 days, will be the country’s first big step towards a manned space mission. It’s the first time the Indian Space Research Organisation (ISRO) will test its “re-entry and recovery” technology. The capsule will fall somewhere in the Bay of Bengal and will be recovered by the Navy.

    Humans Migrated Out of Africa, Then Some Went Back, Study Says Stefan Lovgren for National Geographic News December 14, 2006 Humans first moved out of Africa about 70,000 years ago, but 30,000 years later some of them moved back. That's according to a new study based on DNA evidence from ancient human remains found in Africa. The study shows that a small group of early humans returned to Africa after migrating to the Middle East. In addition, the research suggests that the humans' return occurred around the same time that another group of humans left the Middle East and moved...

    Humans show big DNA differences DNA comparisons: Gains (green), losses (red), the same (yellow) Scientists have shown that our genetic code varies between individuals far more than was previously thought. A UK-led team made a detailed analysis of the DNA found in 270 people and identified vast stretches in their codes to be duplicated or even missing. A great many of these variations are in areas of the genome that would not damage our health, Matthew Hurles and colleagues told the journal Nature. But others are - and can be shown to play a role in a number of disorders....

    Modern Humans, Neanderthals May Have Interbred By E.J. Mundell HealthDay Reporter Mon Oct 30, 5:03 PM ET MONDAY, Oct. 30 (HealthDay News) -- There may be a little Neanderthal in all of us. That's the conclusion of anthropologists who have re-examined 30,000-year-old fossilized bones from a Romanian cave -- bones that languished in a drawer since the 1950s. According to the researchers, these early Homo sapien bones show anatomical features that could only have arisen if the adult female in question had Neanderthal ancestors as part of her lineage. The findings may answer nagging questions: Did modern humans and Neanderthals...

    New strain of bird flu spreads to humans By Roger Highfield, Science Editor Last Updated: 1:27am GMT 31/10/2006 A previously unknown and dangerous strain of the H5N1 bird flu has emerged from southern China and has spread from birds to people in South-east Asia, marking a third wave of avian flu and rekindling fears of a global pandemic. Although the H5N1 avian influenza mostly affects birds and infects people only sporadically, the new strain will once again raise fears that it may mutate or combine with a human virus to form a mutant or hybrid capable of passing from person...

    Ancient human hunters smelt blood on the breeze 26 October 2006 From New Scientist Print Edition. Our ability to detect the characteristic metallic smell left on the skin after handling iron-containing objects like coins and keys may have evolved for a more gory purpose: to help our hunter ancestors track down wounded prey. Fats on the skin break down to form volatile, strong-smelling substances called ketones and aldehydes when they come into contact with iron - whether it comes from the environment or from haemoglobin in blood - says Dietmar Glindemann, a chemist at Virginia Polytechnic Institute and State University...

    WASHINGTON (AP) -- The world -- especially the Western United States, the Mediterranean region and Brazil -- will likely suffer more extended droughts, heavy rainfalls and longer heat waves over the next century because of global warming, a new study forecasts. But the prediction of a future of nasty extreme weather also includes fewer freezes and a longer growing season. In a preview of a major international report on climate change that comes out next year, a study out of the National Center for Atmospheric Research details what nine of the world's top computer models predict for the lurching of...

    Bending the Branches October 18, 2006 A new study of human fossils asks, what if we are the odd ones? (Washington University, St. Louis) Most people think of humans as the top, the apex of the family tree. But new research suggests this quintessentially human infatuation with ourselves may have impaired our judgment. Erik Trinkaus, a paleontologist and Neandertal expert at Washington University in St. Louis, believes that modern human features are unusual enough, compared with ancestral members of the genus Homo, to make us a side branch of the family tree. Neanderthals have generally been seen as evolutionary outcasts,...

    Moth that can kill humans is found breeding in Britain By Charles Clover, Environment Editor (Filed: 14/10/2006) A moth that can be deadly to humans and strips the leaves off oak trees has been found breeding in Britain in what scientists are saying is the result of climate change. The Oak processionary moth is believed to have arrived in oak trees imported from Tuscany and planted on a housing development before infesting the nearby Royal Botanic Gardens, Kew, south-west London. Teams in breathing apparatus were called in to deal with three outbreaks of the moth at Kew a month ago...
