    The taste of beer, without any effect from alcohol itself, can trigger dopamine release in the brain that is associated with drinking and other drugs of abuse, researchers have claimed. Using positron emission tomography (PET), the researchers at Indiana University School of Medicine tested 49 men with two scans, one in which they tasted beer, and the second in which they tasted Gatorade. The researchers were looking for evidence of increased levels of dopamine, a brain neurotransmitter that has long been associated with alcohol and other drugs of abuse. The scans showed significantly more dopamine activity following the taste of...

    This reindeer antler from Neschers in France is engraved with a stylised horse. It was created by early humans and found between 1830 and 1848. A 14,000-year-old engraved reindeer antler is possibly the first piece of early human art ever found. The specimen was uncovered in the 1800s and has been in the vast collections of the Natural History Museum. Its scientific importance, and clues as to how it was made are only now being revealed, scientists report today. Natural History Museum scientists have pieced together the antler's history. It was found between 1830 and 1848 in Neschers, France, by...

    With projections of 9.5 billion people by 2050, humankind faces the challenge of feeding modern diets to additional mouths while using the same amounts of water, fertilizer and arable land as today. Cornell researchers have taken a leap toward meeting those needs by discovering a gene that could lead to new varieties of staple crops with 50 percent higher yields. The gene, called Scarecrow, is the first discovered to control a special leaf structure, known as Kranz anatomy, which leads to more efficient photosynthesis. Plants photosynthesize using one of two methods: C3, a less efficient, ancient method found in most...

    "The prudent man does not make the goat his gardener," says an old Hungarian proverb. But, as I do not live my life according to old Hungarian proverbs, six years ago I added a goat paddock and shed to the rear of my garden and brought home two small dairy goats. The idea took hold of me rather suddenly while I was visiting an acquaintance in Nevada City. She kept goats, and I got to milk one and taste its fresh milk. It tasted ... good! Surprised? I was too.

    Now, John Fa of the Durrell Wildlife Conservation Trust in Trinity, Jersey, says Neanderthals eventually bit the dust because they were unable to adapt their hunting to small animals like rabbits. Fa and his colleagues counted up the skeletons of animals found in three excavation sites in Spain and southern France. Up until 30,000 years ago, the remains of large animals such as deer were abundant in caves. But around that time, coinciding with the disappearance of Neanderthals, rabbit remains became more prevalent. The authors postulate that humans were more successful at switching to catching and eating rabbits. It's not...

    New genetic and archaeological approaches have substantially improved our understanding of the transition to agriculture, a major turning point in human history that began 10,000-5,000 years ago with the independent domestication of plants and animals in eight world regions. In the Americas, however, understanding the initial domestication of New World species has long been complicated by the early presence of an African enigma, the bottle gourd (Lagenaria siceraria). Indigenous to Africa, it reached East Asia by 9,000-8,000 before present (B.P.) and had a broad New World distribution by 8,000 B.P.

    Small dogs the world over can all trace their ancestry back to the Middle East, where the first diminutive canines emerged more than 12,000 years ago. A new study, which appears in BMC Biology, focused on a single gene responsible for size in dogs. Researchers found that the version of the gene IGF1 that is a major determinant of small size in dogs probably originated as a result of domestication of the Middle Eastern gray wolf, which also happens to be smaller than many other wolves. In terms of which came first, big dogs or small dogs, the answer is...

That's what researchers are saying after finding a bone fragment from what they are calling the earliest confirmed domesticated dog in the Americas. University of Maine graduate student Samuel Belknap III came across the fragment while analyzing a dried-out sample of human waste unearthed in southwest Texas in the 1970s. A carbon-dating test put the age of the bone at 9,400 years, and a DNA analysis confirmed it came from a dog — not a wolf, coyote or fox, Belknap said....

    The wide range of variety in domesticated dogs — from the petite Chihuahua to the monstrous mastiff — has powered a new view of what drives evolution. Scientists have long known that the evolutionary changes that alter a species' appearance or create new species frequently occur in rapid bursts. One widely accepted theory holds that any evolutionary change results from a random switch of a single genetic unit within DNA. These single-point mutations occur in about 1 out of every 100 million DNA sites each generation. This frequency is too low to cause rapid evolutionary change, assert John W. Fondon...

Despite being the heavyweights of animal intelligence, chimps were insensitive to what seemed to be obvious hints: They failed to pick up a cup hiding food even when the experimenter stared at it, pointed to it, and even tapped it. Tomasello wanted to talk about what this meant about the limits of nonhuman intelligence. Hare, a pet owner, had a down-to-Earth response: ''My dogs can do this.''</p>

    Scientists believe that two 33,000-year-old skulls unearthed in digs in Siberia and Belgium show dogs were domesticated long before any other animal, such as sheep, cows or goats. Researchers from the University of Arizona said the skulls had shorter snouts and wider jaws than undomesticated animals such as wolves, which use their longer snouts and narrower jaws to help them hunt. That suggested the dogs had been kept for protection and companionship by our ancient ancestors -- just as they are today. The researchers think dogs could have been the first species of animals to be domesticated by humans, long...

Cats have such a superiority complex that they really don't show much guilt about anything. But dogs go completely overboard in the guilt department. You come...

    Washington - Research has long indicated that all dogs, from prissy Pekingese to slobbering St. Bernards, are the domesticated descendants of wolves. But scientists have tussled like puppies over the question of when and where the transition from wild carnivore to newspaper-toting pet began - and why, exactly, dogs and humans have gotten along so well. Now, a new analysis of dog DNA pegs East Asia as the place where wolves and people began their dance of co-domestication - not Europe or the Middle East, as some experts have contended. The work also suggests that domestication began about 15,000 years...

    Dog: man's best friend for over 33,000 years He's been man's best friend for generations. An ancient dog skull found in Siberia and dating back 33,000 years presents some of the oldest known evidence of dog domestication. When combined with a similar find in Belgium, the two skulls indicate that the domestication of dogs by humans occurred repeatedly throughout early human history at different geographic locations -- rather than at a single domestication event, as previously believed. "Both the Belgian find and the Siberian find are domesticated species based on morphological characteristics," said Greg Hodgins, a researcher at the University...

    A Basenji is a dog breed indigenous to sub-Saharan Africa. Humans might have first domesticated dogs from wolves in Africa, with Egypt being one possibility, since wolves are native to that region. Modern humans originated in Africa, and now it looks like man's best friend first emerged there too. An extensive genetic study on the ancestry of African village dogs points to a Eurasian — possibly North African — origin for the domestication of dogs. Prior research concluded that dogs likely originated in East Asia. However, this latest study, the most thorough investigation ever on the ancestry of African village...

    Earliest Domesticated Dogs Uncovered By Jennifer Viegas, Discovery News Skull of a Stone Age Dog April 7, 2003 — The skulls of two Stone Age dogs believed to be the earliest known canines on record have been found, according to a team of Russian scientists. The dog duo, which lived approximately 14,000 years ago, appear to represent the first step of domestication from their wild wolf ancestors. Mikhail Sablin, a scientist at the Zoological Institute of the Russian Academy of Sciences in St. Petersburg, along with his colleague Gennady Khlopachev, analyzed the dog remains, which were found at the Eliseevichi...

    Dogs are no better than wolves at picking up on human cues... When tasked with choosing between two paint cans based on a trainer's hand signal, tamed wolves actually proved more adept at picking the right can. This casts doubt on the idea that domestication some 15,000 years ago imbued dogs with a window into the human mind, says Clive Wynne, an animal psychologist at the University of Florida in Gainesville. Rather, dogs -- and tamed wolves -- probably learn to associate human arm movements with treats, play and affection. Researchers who argue for a dog "theory of mind" are...

    The Cat in Ancient EgyptBy Ilene SpringerAfter the pyramids and the kohl painted eyes, almost nothing evokes more awe and mystery than the fascination ancient Egyptians had with cats.They were not only the most popular pet in the house, but their status rose to that of the sacred animals and then on to the most esteemed deities like no other creature before them.Cats domesticate the ancient EgyptiansAlthough no one can pinpoint the time exactly, we know that the cat was domesticated in Egypt, probably around 2000 B.C., and that most modern cats are descendants of the cats of ancient...

    Dogs make us human By Heidi De Wald Monday, 25 Mar, 2002 About 48% of Australian households own dogs. But can you imagine a world without dogs. And would we be the same if they were not here? Would human beings have developed in very different ways had our best friends not been by our sides? A recent study suggests that the domestication of dogs mutually led to profound changes in the biological and behavioural evolution of both species. It has long been known that the first species domesticated by humans was the wolf. In essence, we made wolves into...

    Scientists argue that friendly wolves sought out humans.In the story of how the dog came in from the cold and onto our sofas, we tend to give ourselves a little too much credit. The most common assumption is that some hunter-gatherer with a soft spot for cuteness found some wolf puppies and adopted them. Over time, these tamed wolves would have shown their prowess at hunting, so humans kept them around the campfire until they evolved into dogs. (See "How to Build a Dog.") But when we look back at our relationship with wolves throughout history, this doesn't really make...

    AbstractThe textual corpus of Bronze Age Mesopotamia is unique in its richness; containing works which appear purely administrative, entirely fictional, or anywhere along a vast spectrum between the two extremes. The present discussion evaluates the major textual genres in terms of their possible uses in reconstructing wider socio-economic dynamics across Mesopotamia: this includes both practical aspects of the agricultural and commercial economies, but also points of ideology centred on complementary themes of fatalistic transience, rejuvenation, and the sensuality of mortals. The two are then linked together by an analysis of legal and haruspical texts, which were written for practical purposes...
  • Turns Out Cats Have Been Walking on Important Stuff for Basically Forever

    Check out this 15th Century manuscript. Notice anything familiar? In totally-non-shocking-news-of-the-day, it turns out cats have been walking on whatever you're writing since the dawn of time. Emir O. Filipovic of the University of Sarajevo's History Department discovered the medieval kitty prints. We can only assume that somewhere, beyond the reach of time, in a small ancient monastery in the mountains, the muffled sounds of "SNOWBALL, OFF. OFF. DOWN. GET DOWN, SNOWBALL. BAD KITTY. DAMNIT, SNOWBALL GO SOMEWHERE ELSE," carry across the medieval vales and valleys.

    SILOAM SPRINGS — Bryan Austin of Siloam Springs thought he’d found a crime scene when he spotted a human skull under a pile of rocks while he was duck hunting in northeast Oklahoma. Looking for a good place to set up a camouflage hunting screen Nov. 19 on a mud flat in the Spavinaw Creek drainage area, Austin found what turned out to be an ancient skull. He later learned that the site is an ancient Indian burial ground. “ It’s absolutely amazing, ” Austin said. “ I’m incredibly interested in this kind of stuff. It’s in my line of...

    Cattle's Call of the Wild: Domestication may hold complex genetic tale Bruce Bower A new investigation of DNA that was obtained from modern cattle and from fossils of their ancient, wild ancestors puts scientists on the horns of a domestication dilemma. The new data challenge the mainstream idea, based on earlier genetic and archaeological evidence, that herding and farming groups in southeastern Turkey or adjacent Near Eastern regions domesticated cattle perhaps 11,000 years ago. According to that view, these groups then introduced the animals throughout Europe, so current European cattle breeds would trace their ancestry directly back to early Near...

    HUMAN beings have spent most of their time on the planet as hunter-gatherers. From at least 85,000 years ago to the birth of agriculture around 73,000 years later, they combined hunted meat with gathered veg. Some people, such as those on North Sentinel Island in the Andaman Sea, still do. The Sentinelese are the only hunter-gatherers who still resist contact with the outside world. Fine-looking specimens—strong, slim, fit, black and stark naked except for a small plant-fibre belt round the waist—they are the very model of the noble savage. Genetics suggests that indigenous Andaman islanders have been isolated since the...
