By Paul Rincon 20 October 2015 Dogs may have become man's best friend in Central Asia, according to the study Today's dogs can trace their origins to Central Asia, according to one of the most comprehensive genetic surveys yet. Dogs are the most diverse animal on the planet - a legacy of thousands of years of selective breeding by humans. But they derive from wild wolves that were gradually tamed and inducted into human hunting groups - perhaps near Mongolia or Nepal. The findings come from an analysis of DNA from thousands of pooches, and are published in PNAS journal....

You may think your dog has an irrational hatred of cats, but their instinct to chase felines out of their territory might be more reasonable than you think. Fossils have revealed the two species have a rocky past after the introduction of cats to the Americas had a devastating effect on the continent's species of wild dogs. In fact, it is thought that competition from cats caused up to 40 species of dog to become extinct in the region millions of years ago.

Before humans milked cows, herded goats or raised hogs, before they invented agriculture, or written language, before they had permanent homes, and most certainly before they had cats, they had dogs. Or dogs had them, depending on how you view the human-canine arrangement. But scientists are still debating exactly when and where the ancient bond originated. And a large new study being run out of the University of Oxford here, with collaborators around the world, may soon provide some answers.

After living alongside humans for thousands of years, it would be nice to think that a bit of our mental agility has rubbed off on dogs. However, it seems that domestic dogs are actually less intellectually capable than the wild relatives they were bred from. Animal psychologists have found that wolves are able to count far better than domestic dogs - and it's because dogs have become used to relying on us to help them.

Man's best friend came about after generations of wolves scavenged alongside humans more than 33,000 years ago in south east Asia, according to new research. Dogs became self-domesticated as they slowly evolved from wolves who joined humans in the hunt, according to the first study of dog genomes. And it shows that the first domesticated dogs came about 33,000 years ago and migrated to Europe, rather than descending from domesticated European wolves 10,000 years ago as had previously been thought.

Humans may have domesticated dogs two separate times, taming wolves both in Europe and Asia thousands of years ago, according to new research. A major international research project may have cleared some of the controversy surrounding the origins of man's best friend, which has until now remained a mystery with two primary hypotheses. The first holds that humans domesticated dogs for the first time in Europe more than 15,000 years ago.

They may be man's best friend, but the question of where domestic dogs originated has long remained a mystery. Some argue that humans first domesticated wolves in Europe, while others claim this happened in Central Asia. Now, a new paper suggests that both these claims may be right, and that dogs were domesticated not once, but twice.

"The Spaniards were much impressed with the productivity of manioc in Arawak agriculture in the Greater Antilles," historian Jonathan Sauer recounts in his history of crop plants. "[A Spanish historian] calculated that 20 persons working 6 hours a day for a month could plant enough yuca to provide cassava bread for a village of 300 persons for 2 years." By all accounts, the Taíno were prosperous -- "a well-nourished population of over a million people," according to Sauer. And yet... lacked the monumental architecture of the Maya or the mathematical knowledge of the Aztec. And most importantly, they were not organized in...

The geology of the site, as well as pollen and algae finds, suggest that the hunter-gatherers encountered the mastodon next to a small pond that both humans and animals used as a water source, the researchers believe. Waters said that the prehistoric "people knew how to find game, fresh water and materials for making tools. These people were well adapted to this environment. The site is a slam-dunk pre-Clovis site with unequivocal artifacts, clear stratigraphy and thorough dating." Another research team previously excavated the site and found what they believed were dog remains, so dogs "would most likely have been...

Chinese archaeologists said they have found a paddy dating back more than 8,000 years, which could be the earliest wet rice farming site in the world. The field, covering less than 100 square meters, was discovered at the neolithic ruins of Hanjing in Sihong county in East China's Jiangsu province in November 2015, according to a spokesman with the archeology institute of Nanjing Museum. At a seminar held in late April to discuss findings at the Hanjing ruins, more than 70 scholars from universities, archeology institutes and museums across the country concluded that the wet rice field was the oldest...

An impressive array of brainpower —“Fat? Blame your genes, say doctors” —“Overweight? Maybe you really can blame your genes” —“Blame your genes for obesity” Headlines such as these have become a staple of science and health journalism. Are they right? Are obese people really helpless victims of their genes? Let us begin by distinguishing between “monogenic” obesity and what scientists call “common” obesity. Monogenic obesity, as the name implies, is caused by a mutation in a single gene, which is inherited in a Mendelian fashion, just as conditions such as sickle-cell anemia and cystic fibrosis are. In the case of...

THE bond between man and dog is so close their hearts actually beat in sync when they are together an astounding new study shows. The heart rates of owners and their dogs become lower when they are in close proximity an experiment that saw heart monitors strapped to dogs and their owners found. The discovery shows dogs have a fundamental role to play in lowering stress says sports scientist Dr Craig Duncan. And canine scientist Mia Cobb says owning a dog can do more than just lower your heart rate. They even recover more quickly from a heart attack, she...

Dairy fats on Iron Age pottery sherds, evidence of pre-historic origin for dairying. The discovery of dairy fats on ancient pottery may indicate dairying high in the Alps occurred as early as the Iron Age over 3000 years ago, according to a study published April 21, 2016 in the open-access journal PLOS ONE by Francesco Carrer from the University of York, UK, and colleagues. Dairy farming has long been an important economic and cultural tradition in the European high Alps, but little is known about when and how the practice originated. Using organic residue analysis, the authors of the present...

The Middle Eastern kingdom needs hay for its 170,000 cows. So, it's buying up farmland for the water-chugging crop in the drought-stricken American Southwest.Saudi Arabia's largest dairy company will soon be unable to farm alfalfa in its own parched country to feed its 170,000 cows. So it's turning to an unlikely place to grow the water-chugging crop — the drought-stricken American Southwest. Almarai Co. bought land in January that roughly doubled its holdings in California's Palo Verde Valley, an area that enjoys first dibs on water from the Colorado River. The company also acquired a large tract near Vicksburg, Arizona,...

The irresistible gaze of "puppy-dog eyes" has roots in thousands of years of human evolution alongside domesticated dogs, says anthropologist Robert Losey. Anyone who owns a dog is familiar with the "gaze" -- that hypnotic, imploring stare that demands reciprocation. It can seem to hold a world of mystery and longing, or just pure bafflement at what makes humans tick. It turns out that the look of mutual recognition between human and dog reflects thousands of years of evolution, a bond programmed into our very body chemistry. Last spring a research team in Japan discovered that both species release a...

Archaeologists working in the borderlands of northern Mexico have uncovered a camp used by ancient hunters as much as 10,500 years ago, revealing insights into some of the earliest human history in the Greater Southwest. On a ranch near the Santa Maria River in northern Chihuahua, researchers have unearthed more than 18,000 artifacts, including thousands of stone flakes, cores, and hammers, along with 370 projectile points, and a dozen stone ovens. But the most surprising find has been the grave of a teenage girl, who was interred among the rocks, alone and unadorned, some 3,200 years ago.

Scientists say they have uncovered the remains of the earliest known massacre victims, dating from approximately 10,000 years ago. Archaeologists believe the victims were members of an extended family group of hunter-gatherers who were slaughtered by a rival group.

200,000 fish bones discovered in and around a pit in Sweden suggest that the people living in the area more than 9000 years ago were more settled and cultured than we previously thought. Research published in the Journal of Archaeological Science suggests people were storing large amounts of fermented food much earlier than experts thought. The new paper reveals the earliest evidence of fermentation in Scandinavia, from the Early Mesolithic time period, about 9,200 years ago. The author of the study, from Lund University in Sweden, say the findings suggest that people who survived by foraging for food were actually...

DNA evidence lifted from the ancient bones and teeth of people who lived in Europe from the Late Pleistocene to the early Holocene -- spanning almost 30,000 years of European prehistory -- has offered some surprises, according to researchers who report their findings in the Cell Press journal Current Biology on Feb. 4, 2016. Perhaps most notably, the evidence shows a major shift in the population around 14,500 years ago, during a period of severe climatic instability... The researchers pieced this missing history together by reconstructing the mitochondrial genomes of 35 hunter-gatherer individuals who lived in Italy, Germany, Belgium, France,...

The carcass was remarkably well preserved, but something was clearly wrong. A rounded hole through the interior jugal. Deep incisions along the ribs. Dents in the left scapula. A broken mandible. This 45,000 year-old mammoth's life ended violently at the hands of hunters. That wouldn't be surprising-it's well known that Pleistocene humans were expert mammoth killers=but for the location. It was excavated from a permafrost embankment at Yenisei bay, a remote spot in central Siberia where a massive river empties into the Arctic Ocean. That makes this brutalized mammoth the oldest evidence for human expansion into the high Arctic by...
