A pointer named “Major” was identified this week as the first known example of a modern dog. A description of the dog was found in a now-obscure 1865 edition of a Victorian journal called The Field. It marks the earliest reported dog breed based on physical form and pedigree. “The invention of ‘breed,’ physically and imaginatively, still shapes how we see and think about dogs today,” Michael Worboys, Director of the University of Manchester’s Centre for the History of Science, Technology and Medicine, told Discovery News. Worboys and his team found the information concerning “Major” while preparing a new museum...

Researchers Have Finally Solved The Mystery Of The Irish Potato Famine Denise Chow, LiveScience May 24, 2013, 12:03 PM The Irish potato famine that caused mass starvation and approximately 1 million deaths in the mid-19th century was triggered by a newly identified strain of potato blight that has been christened "HERB-1," according to a new study. An international team of molecular biologists studied the historical spread of Phytophthora infestans, a funguslike organism that devastated potato crops and led to the famine in Ireland. The precise strain of the pathogen that caused the devastating outbreak, which lasted from 1845 to 1852,...

Keith Cressman of the locust-fighting unit of the United Nations Food and Agriculture Organization said, Sunday, that the locusts crawling around Israel's southern border will start flying in two weeks and be most destructive as they prepare for the trip to the breeding grounds in northern Sudan. Following a tour out in the field, Cressman said he was impressed by the manner and pace of the Agriculture Ministry's determined war on the pests. The ministry is using ground spraying against every swarm that enters from Egypt, with air spraying as needed, around the clock. It noted that there were fewer...

Europe is on the brink of a landmark ban on the world's most widely used insecticides, which have increasingly been linked to serious declines in bee numbers. Despite intense secret lobbying by British ministers and chemical companies against the ban, revealed in documents obtained by the Observer, a vote in Brussels on Monday is expected to lead to the suspension of the nerve agents. Bees and other insects are vital for global food production as they pollinate three-quarters of all crops. The plummeting numbers of pollinators in recent years has been blamed on disease, loss of habitat and, increasingly, the...

will always remember the day I woke to the news that more than 2,000 fires were burning in California. I thought I must not have heard correctly. Two thousand fires? How could that be? In the end, the state's brave firefighters, joined by contingents from out of state, won the battle. But not before 11 emergency declarations were issued and more than 400,000 acres burned. Countless lives and livelihoods were ruined. Today, there's a new disaster looming, and although it's not as riveting or dramatic as walls of flames and billowing black smoke, it needs our immediate attention. The draft...

Matt Miller, an Idaho-based science writer with The Nature Conservancy, says rodents and other small livestock represent a low-impact meat alternative to carbon-costly beef. Miller, who is writing a book about the ecological benefits of eating unconventional meats, visited Colombia several years ago. At the time, he says, conservation groups were expressing concern about local ranchers clearing forest to provide pasture for their cattle — activity that was causing erosion and water pollution. "They were encouraging people to switch from cattle to guinea pigs," Miller says. "Guinea pigs don't require the land that cattle do. They can be kept in...

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...

THE Supreme Court has frequently handed down judgments that have shaken America to its core. Now, it has turned its attention to the raisin. A group of farmers has brought a complaint about the Agricultural Marketing Agreement Act of 1937, under which the government confiscates part of the annual national raisin crop. The Court is considering whether the arrangement is constitutional. But why is a country that generally celebrates red-blooded capitalism regulating the raisin trade in the first place?Since the 1940s a government agency called the Raisin Administrative Committee has confiscated a portion of the annual raisin crop: 47% in 2003 and...

It is with great sadness and a heavy heart that we regret to inform you that late last night President Barack Obama signed H.R. 933, which contained the Monsanto Protection Act into law. This is an outrage that will not go unanswered. While we are still waiting to hear from the administration all the final details, we understand at this time that Section 735, the Monsanto biotech rider is intact. President Obama knowingly signed the Monsanto Protection Act over the insistence of more than 250,000 Americans who signed an urgent letter asking that he use his executive authority to veto...

President Barack Obama used Washington’s grandest stage—the State of the Union speech—to announce negotiations with Europe aimed at creating the world’s largest free trade agreement. Just weeks later, there are signs that old agriculture disputes could be deal-killers. European Union leaders don’t want the negotiations to include discussions on their restrictions on genetically modified crops and other regulations that keep U.S. farm products out of Europe. But Obama says it’s hard to imagine an agreement that doesn’t address those issues. Powerful U.S. agricultural lobbies will do their best to make sure Congress rejects any pact that fails to address the...

Matt Ridley, author of The Red Queen, Genome, The Rational Optimist and other books, dropped by Reason's studio in Los Angeles last month to talk about a curious global trend that is just starting to receive attention. Over the past three decades, our planet has gotten greener! Even stranger, the greening of the planet in recent decades appears to be happening because of, not despite, our reliance on fossil fuels. While environmentalists often talk about how bad stuff like CO2 causes bad things to happen like global warming, it turns out that the plants aren't complaining. Approximately 19 minutes. Produced...

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...

Sumant Kumar was overjoyed when he harvested his rice last year. There had been good rains in his village of Darveshpura in north-east India and he knew he could improve on the four or five tonnes per hectare that he usually managed. But every stalk he cut on his paddy field near the bank of the Sakri river seemed to weigh heavier than usual, every grain of rice was bigger and when his crop was weighed on the old village scales, even Kumar was shocked. This was not six or even 10 or 20 tonnes. Kumar, a shy young farmer...

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...

SAN FRANCISCO (CBS SF) – A San Francisco food producer wants to make you an omelet without breaking any eggs – and they may be able to do it with one key ingredient they make in a lab – no chicken required. From their Mission District laboratory, Hampton Creek Foods and CEO Josh Tetrick are taking aim at the egg farming industry. “We just cannot go on eating like we all are right now with our food system,” Tetrick said. “It’s just unsustainable.” Many Bay Area farms let chickens roam the pastures, but the Humane Society says more than 90%...

It was a productive day for Gary Strader when he pulled his vehicle up to a remote site in northeast Nevada and found nine coyotes caught in leg hold snares set by the federal government. As was routine, Strader, a former trapper with the U.S. Department of Agriculture, signaled his dogs to attack. His supervisor, who had accompanied him that day, watched and laughed as the dogs circled the coyotes and ripped into them, Strader recalled. "That was regular practice," said Strader, who in 2009 left Wildlife Services, a little-known program within the USDA. The program is tasked with humanely...

"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. But I learned that goat milk from the store often...

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...

Humans and dogs enjoy a prehistoric relationship, a longstanding bond with its origins in a time when dogs as we know them evolved from wild animals into our domesticated companions. Now, a canine living in a manner similar to that of dogs from those ancient days may have been discovered in isolated stretches of longleaf pines and cypress swamps in the American Southeast. The Carolina Dog, a familiar-looking animal long known in the rural South as the "yaller dog," may be more than the common mutt that immediately meets the eye. I. Lehr Brisbin, Jr., Senior Ecologist at the University...

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. Here we integrate genetic and archaeological approaches to address a...

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...

Only 40 genes separate your pet dog from a wolf By Roger Highfield, Science Editor (Filed: 22/11/2005) The difference between an obedient, friendly dog and a big bad wolf could be down to as few as 40 genes, according to a study into tameness. The research also found that to adapt to a life on the farm or in the home takes many more changes in gene activity than that required to love humans. A Swedish team compared two groups of farm-raised silver foxes in Siberia, one where for 40 generations the foxes have been selected for their friendly nature,...

When People Fled Hyenas By Lee Dye Special to ABCNEWS.com Nov. 20 — Deep inside a cave in Siberia's Altai Mountains, Christy Turner and his Russian colleagues may have found an answer to a question that has hounded him for more than three decades. As a young anthropologist, Turner spent time in Alaska's Aleutian Islands in the 1970s, working at several archaeological sites and occasionally gazing westward toward Siberia. "I thought, 'That's the place that Native Americans came from,' " he says now from his laboratory at Arizona State University in Tempe. But why, he wondered then as he still...

PORTLAND, Maine — Nearly 10,000 years ago, man's best friend provided protection and companionship — and an occasional meal. 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...

Today's dogs are all descended from a pack of wolves tamed 16,000 years ago on the shores of the Yangtze river, according to new research. It was previously known that the birthplace of the dog was eastern Asia but historians were not able to be more precise than that. However, now researchers have made a number of new discoveries about the history of man's best friend - including that the dog appeared about 16,000 years ago south of the Yangtze river in China. It has also been discovered that even though the dog has a single geographical origin it descends...

Cats' Family Tree Rooted In Fertile Crescent, Study ConfirmsCats, with their penchant for hunting mice, rats and other rodents, became useful companions as people domesticated, grew and stored wild grains and grasses. Eventually, cats also became pets but were never fully domesticated. Even today, most domestic cats remain self-sufficient, if necessary, and continue to be efficient hunters, even when provided with food. (Credit: Michele Hogan) ScienceDaily (Jan. 29, 2008) — The Fertile Crescent of the Middle East has long been identified as a "cradle of civilization" for humans. In a new genetic study, researchers at the University of California, Davis,...

Derr acknowledges that the story of the dog’s emergence (as distinct from its evolutionary forebear, the wolf) cannot be “neatly distilled.” Different estimates place the first appearance of dog-like creatures anywhere from 12,000 to 135,000 years ago. But Derr argues that the dog itself was an “evolutionary inevitability.” He suggests that dogs and humans — similar animals who “simply took to traveling with each other” tens of thousands of years ago, “and never stopped” —

<p>Domesticated animals look - and act - differently from than their wild counterparts. Why?</p>
<p>The experiment was derived out of a discussion student Brian Hare had with his adviser, Michael Tomasello, an expert in primate behavior at Emory University. They were talking about how bad chimpanzees were at understanding human social cues. 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>
