DNA Study Contradicts Human/Chimp Common Ancestry by Brian Thomas, M.S. | Nov. 15, 2011 Evolutionary biologists argue that since human and chimp DNA are nearly identical, both species must have evolved from a common ancestor. However, creation scientists have pointed out that their DNA is, in fact, very dissimilar. The vast majority of each species' DNA sequence is not genes, but instead regulated gene expression. A new report unmistakably confirmed that the regulatory DNA of humans is totally different from that of chimps, revealing no hint of common ancestry. Biologist John F. McDonald, of the Georgia Institute of Technology's School...

Dolphins "talk" to each other, using the same process to make their high-pitched sounds as humans, according to a new analysis of results from a 1970s experiment. The findings mean dolphins don't actually whistle as has been long thought, but instead rely on vibrations of tissues in their nasal cavities that are analogous to our vocal cords.

LEBANON, New Hampshire (Reuters) - Presidential candidate Mitt Romney, in danger of losing his 2012 Republican primary front-runner status, on Wednesday tweaked his position on global climate change, saying he does not know if humans are the primary cause. Romney, the former Massachusetts governor, also said he would not place restrictions on carbon emissions if elected and did not favor spending heavily on climate solutions. He was asked about global warming at a town hall meeting in Lebanon, New Hampshire, and said he believed the world is getting hotter and humans contribute in some way to the change. "Do I...

Explosive volcanic eruptions might be attention grabbing, but a new review of research finds that their environmental impact pales in comparison to human activities. According to the research, humans put out the same amount of carbon dioxide in three to five days that all of the volcanoes on Earth put out in one year. "Anthropogenic carbon dioxide emissions dwarf global volcanic carbon dioxide emissions," study researcher Terrance Gerlach, of the U.S. Geological Survey, said in a statement. Carbon dioxide, or CO2, is the main greenhouse gas responsible for climate change. Gerlach crunched the carbon dioxide numbers from earlier studies of...

An improvement in the dating of fossils suggests that the Neanderthals, a heavily muscled, thick-boned human species adapted to living in ice age Europe, perished almost immediately on contact with the modern humans who started to enter Europe from the Near East about 44,000 years ago. Until now bones from several Neanderthal sites have been dated to as young as 29,000 years ago, suggesting there was extensive overlap between the two human species. This raised the question of whether there had been interbreeding between humans and Neanderthals, an issue that is still not resolved. RSS Feed RSS Get Science News...

The first modern people evolved in southern Africa more than 60,000 years ago - and not in the east of the continent as most scientists believe, a study concludes. After analysing DNA samples from 27 populations in modern-day Africa, researchers say the most likely location for the 'cradle of humanity' is the Kalahari desert region of South Africa, Namibia and Botswana. The modern-day click-speaking bushman from the desert show the greatest genetic diversity of any Africans - suggesting that their home was the birthplace of the first true Homo sapiens. Originators: The home of the modern day click-speaking bushman in...

Humans, versus other great apes, are built for running fast and long as opposed to very impressive strength, but what about Neanderthals? If a modern human and a Neanderthal competed in a marathon, who would win? (Comparison of Neanderthal and Modern Human skeletons. Credit: K. Mowbray, Reconstruction: G. Sawyer and B. Maley, Copyright: Ian Tattersall) In a short sprint, the Neanderthal might have had a chance, but most fit humans would always win longer races, suggests new research accepted for publication in the Journal of Human Evolution. Anthropologist David Raichlen of the University of Arizona and his colleagues determined that...

A new University of Florida study following the evolution of lice shows modern humans started wearing clothes about 170,000 years ago, a technology which enabled them to successfully migrate out of Africa. Principal investigator David Reed, associate curator of mammals at the Florida Museum of Natural History on the UF campus, studies lice in modern humans to better understand human evolution and migration patterns. His latest five-year study used DNA sequencing to calculate when clothing lice first began to diverge genetically from human head lice. Funded by the National Science Foundation, the study is available online and appears in this...

Genetically modified crops may have once been cutting edge, but now there is a new frontier - genetically modified animals.

Scientists say an entirely separate type of human identified from bones in Siberia co-existed and interbred with our own species.The ancient humans have been dubbed "Denisovans" after the caves in Siberia where their remains were found. There is also evidence that this population was widespread in Eurasia. A study in Nature journal shows that Denisovans co-existed with Neanderthals and interbred with our species - perhaps around 50,000 years ago. An international group of researchers sequenced a complete genome from one of the ancient hominins (human-like creatures), based on nuclear DNA extracted from a finger bone.

Harvard scientists were surprised that they saw a dramatic reversal, not just a slowing down, of the ageing in mice. Now they believe they might be able to regenerate human organs Scientists claim to be a step closer to reversing the ageing process after rejuvenating worn out organs in elderly mice. The experimental treatment developed by researchers at the Dana-Farber Cancer Institute, Harvard Medical School, turned weak and feeble old mice into healthy animals by regenerating their aged bodies. The surprise recovery of the animals has raised hopes among scientists that it may be possible to achieve a similar feat...

A new study published in the peer reviewed journal Climate Change revealed that the phenomenon of global warming is likely to lead to lower human death rates. The research by professors Christidis, Donaldson, and Stott found that 0.7 deaths per million persons per year could be attributed to higher temperatures in the hottest areas, while 85 deaths per million persons per year could be attributed to lower temperatures in the coldest areas. For every one life lost due to increased heat 121 lives are saved. Climate guru Al Gore challenged the premises of the research as “possibly racist and most...

Humans were problem for Discovery Channel attackerBy Gary Harmon Sunday, September 5, 2010 Well, that’s one way to reduce the surplus population. Al Gore acolyte James J. Lee managed to get himself offed by a police sharpshooter after taking over the Discovery Communications headquarters in Silver Spring, Md., on Wednesday. No word on whether the sharpshooter used EPA-approved ammunition in the job, not that it should matter. In some quarters, though, such issues weigh heavily. Wouldn’t want the lethal projectile to harm the environment, after all. Lee, it turns out, might be one who would have wished to be ushered...

Our happy hour fact to amaze your drinking buddies with. In an experiment involving lab rats, sex was correlated with adult brain growth. Since previous studies have shown that stressful, unpleasant situations can hinder brain growth, researchers from Princeton University wanted to see if stressful but pleasurable situations -- like sex -- would achieve the opposite effect. So, they divided male lab rats into three groups: The rats in one group were given sex partners daily, the second group got set up with female companionship once every two weeks and the third group got nothing at all. The rats that...

It will go down as a landmark decision. U.S. District Judge OIiver W. Wagner ruled this week that people have rights. That may sound a bit daffy but in the wacky world of California water politics people take second class citizen status behind fish and even vegetation. In a nutshell, Wagner ruled that federal water officials must consider humans along with fish when it comes to divvying up how California’s most precious resource – water – is discharged or moved through the Delta. The judge also directed the federal government to stop using what he termed “guestimations” instead of precise...

The new species of hominid, the evolutionary branch of primates that includes humans, is to be revealed when the two-million-year-old skeleton of a child is unveiled this week. Scientists believe the almost-complete fossilised skeleton belonged to a previously-unknown type of early human ancestor that may have been a intermediate stage as ape-men evolved into the first species of advanced humans, Homo habilis. Experts who have seen the skeleton say it shares characteristics with Homo habilis, whose emergence 2.5 million years ago is seen as a key stage in the evolution of our species. The new discovery could help to rewrite...

Link only - Humans must be to blame for climate change, say scientists

WASHINGTON (Reuters) – Scientists have sequenced the DNA from four frozen hairs of a Greenlander who died 4,000 years ago in a study they say takes genetic technology into several new realms. Surprisingly, the long-dead man appears to have originated in Siberia and is unrelated to modern Greenlanders, Morten Rasmussen of the University of Copenhagen and colleagues found. "This provides evidence for a migration from Siberia into the New World some 5,500 years ago, independent of that giving rise to the modern Native Americans and Inuit," the researchers wrote in Thursday's issue of the journal Nature. Not only can...

Bird influenza viruses have a variety of strategies to cross the species barrier and spreadThe 2009 H1N1 influenza virus used a new strategy to cross from birds into humans, a warning that it has more than one trick up its sleeve to jump the species barrier and become virulent. In a report in this week's early online edition of the journal Proceedings of the National Academy of Sciences, University of California, Berkeley, researchers show that the H1N1, or swine flu, virus adopted a new mutation in one of its genes distinct from the mutations found in previous flu viruses, including...

We are currently the only human species alive, but as recently as 24,000 years ago another one walked the earth — the Neanderthals. These extinct humans were the closest relatives we had, and tantalizing new hints from researchers suggest that we might have been intimately close indeed. The mystery of whether Neanderthals and us had sex might be solved if the entire Neanderthal genome is reported soon as expected. The matter of why they died and we succeeded, however, remains an open question. Maybe not nasty and brutish, but still short Why did Neanderthals go extinct? Roughly 30,000 years ago,...

SEDIMENT cores from a small Arctic lake in Canada stretching back 200,000 years show unprecedented gains in global warming since 1950, indicating human activity is the likely cause. "The past few decades have been unique in the past 200,000 years in terms of the changes we see in the biology and chemistry recorded in the cores,'' University of Colorado glaciologist Yarrow Axford said. "We see clear evidence for warming in one of the most remote places on Earth at a time when the Arctic should be cooling because of natural processes." Mr Axford is the chief author of the study...

To the Editor: The Naval Health Research Center serves as the Navy hub for the Department of Defense's Global Emerging Infections Surveillance and Response System (GEIS), in which it monitors influenza-like illness among recruit trainees of all military services, military dependents, and crew members of large Navy ships (population, >1000). The center works in collaboration with the Border Infectious Disease Surveillance Project of the Centers for Disease Control and Prevention (CDC), which monitors populations located on the border between California and Mexico. The first two human cases of novel swine-origin influenza A (H1N1) virus (S-OIV), known as swine flu, in...

VIENNA (AFP) – They can make fabric resistant to stains, improve the taste of food and help drug research, but nanoparticles could also pose a danger to human health, experts warned Wednesday. Susanne Stark, of the Consumer Information Association, told a seminar in the Austrian city of Salzburg that companies should be forced to indicate on labels whether a product contains the tiny particles. "There are more questions than answers on the effects of nanoparticles" on human health, the chemist said. Cosmetic and food products should indicate whether their products contain nanoparticles by 2012, she said. Nanoparticles, measuring no more...

When we daydream about the future, we tend to focus on the fabulous belongings we're going to have. Jet packs, flying cars, weapons to kill aliens, cell phones that make today's sleek models look clunky -- you name it, we're going to have it. We don't tend to focus, however, on who we'll be in the future. Most of us probably picture ourselves exactly the same, though maybe thinner, as surely we'll all have robot personal trainers by then. While we see the world's technology evolving to meet our needs, we may not think about how we ourselves might be...

Cat owners may have suspected as much, but it seems our feline friends have found a way to manipulate us humans. Researchers at the University of Sussex have discovered that cats use a "soliciting purr" to overpower their owners and garner attention and food. Unlike regular purring, this sound incorporates a "cry", with a similar frequency to a human baby's. The team said cats have "tapped into" a human bias - producing a sound that humans find very difficult to ignore.

If you've ever wondered who's in control, you or your cat, a new study points to the obvious. It's your cat. Household cats exercise this control with a certain type of urgent-sounding, high-pitched meow, according to the findings. This meow is actually a purr mixed with a high-pitched cry. While people usually think of cat purring as a sign of happiness, some cats make this purr-cry sound when they want to be fed. The study showed that humans find these mixed calls annoying and difficult to ignore. "The embedding of a cry within a call that we normally associate with...

A fossil discovery bears marks of butchering similar to those made when cutting up a deerOne of science's most puzzling mysteries - the disappearance of the Neanderthals - may have been solved. Modern humans ate them, says a leading fossil expert. The controversial suggestion follows publication of a study in the Journal of Anthropological Sciences about a Neanderthal jawbone apparently butchered by modern humans. Now the leader of the research team says he believes the flesh had been eaten by humans, while its teeth may have been used to make a necklace.

snip It's even conceivable, he said, that our genes eventually will change enough to create an entirely new human species, one no longer able to breed with our own species, Homo sapiens. "Someday in the far distant future, enough genetic changes might have occurred so that future populations could not interbreed with the current one,'' Sussman said in an e-mail message. snip It's also the topic of a new book, "The 10,000 Year Explosion,'' by anthropologists Henry Harpending and Gregory Cochran of the University of Utah, Salt Lake City. "For most of the last century, the received wisdom in the...

Los Angeles, CA – A new study in the journal Personal Relationships reveals that women prefer mates who are recognized by their peers for their skills, abilities, and achievements, while not preferring men who use coercive tactics to subordinate their rivals. Indeed, women found dominance strategies of the latter type to be attractive primarily when men used them in the context of male-male athletic competitions. Jeffrey K. Snyder, Lee A. Kirkpatrick, and H. Clark Barrett conducted three studies with college women at two U.S. universities. Participants evaluated hypothetical potential mates described in written vignettes. The studies were designed to examine...

SACRAMENTO, Calif. -- California's utilities, refineries and large factories must transform their operations to cut greenhouse gas emissions as part of a new climate plan before state regulators. On Thursday, the California Air Resources Board was expected to adopt what would be the nation's most sweeping global warming plan, outlining for the first time how individuals and businesses would meet a landmark 2006 law that made the state a leader on global climate change. It would hold California's worst polluters accountable for the heat-trapping emissions they produce _ transforming how people travel, utilities generate power and businesses use electricity. At...

NASA and other spaceflight programs worldwide should focus on putting people on Mars, not the moon, an advocacy group for space exploration said in a new plan announced today. "The U.S. landed humans on the Moon nearly 40 years ago," said Louis Friedman, executive director of The Planetary Society. "Returning to the moon has not sufficiently excited the public and will require resources that will be badly needed elsewhere in the space program."

The latest request from the Pentagon jars the senses. At least, it did mine. They are looking for contractors to provide a "Multi-Robot Pursuit System" that will let packs of robots "search for and detect a non-cooperative human". One thing that really bugs defence chiefs is having their troops diverted from other duties to control robots. So having a pack of them controlled by one person makes logistical sense. But I'm concerned about where this technology will end up. Given that iRobot last year struck a deal with Taser International to mount stun weapons on its military robots, how long...

Ore. Discovery Challenges Beliefs About First Humans Until recently, most scientists believed that the first humans came to the Americas 13,000 years ago. But new archaeological findings from a cave in Oregon are challenging that assumption. Lee Hochberg of Oregon Public Television reports on the controversial discovery. LEE HOCHBERG, NewsHour correspondent: What archaeologist Dennis Jenkins found in the Paisley Caves in south central Oregon may turn on its head the theory of how and when the first people came to North America. Many scientists believe humans first came to this continent 13,000 years ago across a land bridge from Asia...

Humans Wore Shoes 40,000 Years Ago, Fossil SuggestsScott Norris for National Geographic NewsJuly 1, 2008 Humans were wearing shoes at least 10,000 years earlier than previously thought, according to a new study. The evidence comes from a 40,000-year-old human fossil with delicate toe bones indicative of habitual shoe-wearing, experts say. A previous study of anatomical changes in toe bone structure had dated the use of shoes to about 30,000 years ago. Now the dainty-toed fossil from China suggests that at least some humans were sporting protective footwear 10,000 years further back, during a time when both modern humans and Neandertals...

First Shoes Worn 40,000 Years Ago Maggie Koerth-Baker Special to LiveScience LiveScience.com Thu Jun 5, 9:05 AM ET Humans started wearing shoes about 40,000 years ago, much earlier than previously thought, new anthropological research suggests. As any good clothes horse knows, the right outfit speaks volumes about the person wearing it. Now, anthropologists are tapping into that knowledge base, looking for the physical changes caused by wearing shoes to figure out when footwear first became fashionable. Turns out, clothes really do make the man (and the woman), at least when it comes to feet. That's because wearing shoes changes the...

Humans May Have Come To New Zealand Later Than ThoughtHumans Arrived In New Zealand 1,000 Years Later Than Believed, New Study Finds WELLINGTON, New Zealand, Jun. 3, 2008 (AP) Radiocarbon dating of rat bones and rat-gnawed seeds reinforces a theory that human settlers did not arrive in New Zealand until 1300 A.D. _ about 1,000 years later than some scientists believe, according to a study released Tuesday. The first settlement date "has been highly debated for decades," said Dr. Janet Wilmshurst, a New Zealander who led the international team of researchers in the four-year study. The team carbon dated rat...

Beringia: humans were hereIt was an extraordinary ancient land filled with fantastic creatures and intrepid people. ALEX ROSLIN, Special to The Gazette Published: Saturday, May 17 Beringia is thought by a handful of renegade scientists to be a prehistoric homeland for aboriginal people who later spread across the Americas and the key to one of archeology's greatest Holy Grails - figuring out how humans first got to this continent. This July, Jacques Cinq-Mars, a renowned archeologist living in Longueuil, is heading to Beringia - a vast territory that once spanned the Yukon, Alaska and Siberia - in hopes of resolving...

WASHINGTON: Human beings for 100,000 years lived in tiny, separate groups, facing harsh conditions that brought them to the brink of extinction, before they reunited and populated the world, genetic researchers in a study said on Thursday. "Who would have thought that as recently as 70,000 years ago, extremes of climate had reduced our population to such small numbers that we were on the very edge of extinction," said paleontologist Meave Leakey, of Stony Brook University, New York. The genetic study examined for the first time the evolution of our species from its origins with "mitochondrial Eve," a female hominid...

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...
