    'Extinct' wild horse roams again By Charles Clover (Filed: 19/12/2005) The wild horse has been saved from extinction after a successful programme to reintroduce captive-bred horses to their natural habitat in Mongolia. A working group of scientists at London Zoo has now recommended that Przewalski's horse, previously characterised as "extinct" in the wild, should now be listed as "endangered". It is a rare case of a species climbing away from extinction. If the new status is accepted by IUCN, the World Conservation Union, scientists say it will be a milestone for large mammal conservation. In 1945, there were only 31...

    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...

    ...As I mentioned before, many Native Americans believe that horse was in America many centuries before Columbus. Pony Boy gives one of such traditional narratives in his book, although, it needs to be noted, he generally tends to support the mainstream academic view of horse history in America. Here's a picture of a very unusual "Przewalski horse". This wild horse is still found in Mongolia. It is so different, it has 66 chromosomes as compared to the 64 that we find in all other horses. This is a very primitive kind of horse, the one probably quite similar to what...

    US scientists have found that all modern varieties of potatoes can be traced back to a single source - a spud grown in Peru over 7,000 years ago. It had been believed potatoes had a much wider region of origin, stretching from Peru to northern Argentina. The team, led by Dr David Spooner of the University of Wisconsin-Madison, analysed the DNA of about 360 potatoes, both wild and cultivated. Some 300 million tonnes of potatoes are produced around the world every year. The study was sponsored by the US Department of Agriculture. Dr Spooner, a professor of horticulture, said archaeological...

    Ancient site reveals stories of sacrificed horses www.chinaview.cn 2005-08-24 14:15:53 BEIJING, Aug. 24 -- A trip to Zibo might leave you with the similar impression as to a trip to Xi'an, especially when you visit the relics of horses buried for sacrifice. Zibo, in east China's Shandong Province, is the location of the state of Qi's capital in the Spring and Autumn Period (770-476 BC). During this period, five feudal lords were able to gain control over the other states, with Duke Huan of Qi the head of the five. The difference between the horse buried for sacrifice in Zibo...

    Genetic evidence is shedding new light on the origins of horses in the New World, during a particularly hazy period in their evolution. As the Great Ice Age came to an end, some 11,000 years ago, North America was thought to be home to as many as 50 species and subspecies of horse. But studies of ancient DNA tell a rather different story, suggesting the horses belonged to just two species. These are the stilt-legged horses, now extinct, and the caballines. The caballines are thought to be the ancestors of today's domestic horse. "It looks like, as far as we...

    ST. THOMAS, Barbados - It's male. But what is it? A zonkey? A deebra? That's the debate in Barbados since a zebra gave birth to a foal sired by a donkey. Alex was born April 21, a milk-chocolate brown creature with the black stripes of a zebra on his ears and legs. His face looks more like a horse, with a distinctive black "V" patch on the forehead. "It's really funny and a little bit freaky," said Natalie Harvey, a 29-year-old waitress. "I was stunned to hear about such a weird thing happening here." While zebra hybrids are not uncommon,...

In contrast, new genetic data reveal multiple centers of domestication across Eurasia and that European, rather than Near Eastern, wild boar are the...

    How prehistoric farmers saved us from new Ice Age Robin McKie, science editor Sunday March 6, 2005 The Observer Ancient man saved the world from a new Ice Age. That is the startling conclusion of climate researchers who say man-made global warming is not a modern phenomenon and has been going on for thousands of years. Prehistoric farmers who slashed down trees and laid out the first rice paddies and wheatfields triggered major alterations to levels of greenhouse gases such as methane and carbon dioxide in the atmosphere, they say. As a result, global temperatures - which were slowly falling...

    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...

    Donkey domestication began in Africa 19:00 17 June 04 NewScientist.com news service Genetic fingerprints indicate that wild African asses were the ancestors of domestic donkeys, making donkeys the only important domestic animal known to come from Africa. Animal domestication was a key development in human culture. Meat animals came first, with cattle, sheep, goats and pigs initially domesticated between 10,000 and 11,000 years ago. Animals useful for carrying loads and people, such as horses, donkeys and camels, came in a later wave about 5000 years ago, which enhanced trade and mobility. Donkeys were particularly important, being smaller, more durable and...

    Prehistoric row erupts over hunter-gatherer riddle February 19, 2004 - 12:22PM A team of Australian archaeologists have sparked an academic row by claiming to have solved the riddle of a missing 1,000 years in human prehistory. The scientists from Melbourne's La Trobe University have found remnants of grains on the shore of the Dead Sea in Jordan that they believe help fill the 1,000-year gap in our knowledge of man's transition from nomad to farmer. But not everyone agrees, and the Australian team is now muscling up for an academic arm wrestle next month with the exponents of different theories...

    Scientists Say They've Cloned a Horse By RICK CALLAHAN, Associated Press Writer Scientists in Italy say they have created the world's first cloned horse, raising the possibility of a sequel to the next Seabiscuit or a carbon copy of Kentucky Derby champion Funny Cide. The small, sturdy work horse is now two months old, weighs about 220 pounds and is in excellent health, said its creators. Their announcement beats a Texas A&M team awaiting the birth of its own horse clone. The cloned Haflinger horse is named Prometea after Prometheus, the character in Greek mythology who stole fire from the...

    Biologists chase down pooches' genetic and social past A Shaggy Dog History Two-kilogram teacup poodles; 90-kg mastiffs; slender greyhounds; squat English bulldogs: For a single species, canines come in a vast array of shapes and sizes. Even more remarkably, they all come from the same stock. Many millennia ago, humans took in a few primitive wolves and made them man's best friend. Or so the story goes. For centuries, researchers have doggedly pursued the evolutionary and social history of canines, with mixed success. Only subtle differences distinguish dogs from coyotes, jackals, and other canids, making family trees difficult to construct...

    World's dogs are descended from Asian wolves Scientists have found that almost all dogs share a common gene pool after analysing the DNA of hundreds of dogs from Europe, Asia, Africa and North America. They have concluded domesticated dogs originated from wolves in East Asia nearly 15,000 years ago. The animals travelled with humans through Europe and Asia and across the Bering Strait with the first settlers in America. Swedish and Chinese scientists studied the genes of 654 dogs and found a higher genetic diversity among East Asian dogs suggested that people there were the first to domesticate dogs from...

    The story of how wild horses were tamed by ancient people has been pieced together by gene hunters. DNA evidence shows modern horses are descended from not one but several wild populations. It suggests horses were domesticated - for meat, milk or to carry loads - in more than one place. As few as 77 wild mares passed on their genes to today's modern horse breeds, from the American mustang to the Shetland pony. "We see traces of original wild populations of horses that have been incorporated into the domestic horses of today," says co-researcher Dr Peter Forster of the...

    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...
