They have lived in our homes, been members of the family, slept on our laps for over 10,000 years. Yet it is only recently that science has begun to answer how it is that cats and dogs came to be our most prized companion animals - discovering, along the way, how the domestication of cats and dogs actively helped change the course of human history. "Domestication," says scientist Carlos Driscoll, "is evolution that we can see." Driscoll is a researcher at Oxford University and the National Cancer Institute in Maryland, where much of the world's leading work on cats has...

Called BAZ1B, it may also help explain why domesticated animals look cuter than their wild kin Domestic animals’ cuteness and humans’ relatively flat faces may be the work of a gene that controls some important developmental cells, a study of lab-grown human cells suggests. Some scientists are touting the finding as the first real genetic evidence for two theories about domestication. One of those ideas is that humans domesticated themselves over many generations, by weeding out hotheads in favor of the friendly and cooperative (SN: 7/6/17). As people supposedly selected among themselves for tameness traits, other genetic changes occurred that...

Viking Cats – DNA Study Shows the Crucial Role Felines Played in Viking Life Apr 12, 2019 Reginald Martyr After conducting extensive research, scientists believe that they have stumbled upon an interesting revelation concerning the history of cats, a species which is among the world’s most popular pets today. New findings suggest that eons before cats became household pets across the globe, they were the frequent companions of ancient Vikings, in some cases accompanying them as they sailed across the globe. The first-ever major examination and analysis of ancient DNA from our feline friends provided these rather unexpected preliminary conclusions...

...In the genetic analysis, published in 2007, Driscoll, another of us (O'Brien) and their colleagues focused on two kinds of DNA that molecular biologists traditionally examine to differentiate subgroups of mammal species: DNA from mitochondria, which is inherited exclusively from the mother, and short, repetitive sequences of nuclear DNA known as microsatellites. Using established computer routines, they assessed the ancestry of each of the 979 individuals sampled based on their genetic signatures. Specifically, they measured how similar each cat's DNA was to that of all the other cats and grouped the animals having similar DNA together. They then asked whether...

BISHOPVILLE, S.C. — Inside a fenced acre on the swampy Lynches River flood plain in central South Carolina, seven of Don Anderson’s primitive dogs spring into high alert at approaching strangers. Medium-sized, they fan out amid his junkyard of improvised habitat: a few large barrels to dig under, an abandoned camper shell from a pickup, segments of black plastic water pipe and backhoed dirt mounds overgrown with waist-high ragweed. These are Carolina dogs, and though they are friendly, one can instantly sense they are different from other dogs. Several rush to the gate, their whole bodies wagging eagerly. Others sprint...

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....

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...

When it comes to sheer friendliness, few humans can match the average dog. But people with Williams syndrome may come close, their unusual genetics granting them a puppyish zeal for social interaction. Now, scientists have found that extreme friendliness in both species may share common genetic roots. A friendly condition Williams syndrome, also known as Williams-Beuren syndrome, occurs when people are missing of a chunk of DNA containing about 27 genes. The syndrome affects about one in 10,000 people, and it is associated with a suite of mental and physical traits, including bubbly, extroverted personalities, a broad forehead, full cheeks,...

Results point to a single origin for modern canines and push back the timing by thousands of years. Researchers chasing the origin of modern dogs find that canines were domesticated once, between 20,000 and 40,000 years ago. The results, published on 18 July in Nature Communications1, push back against a controversial 2016 study2 that suggested dogs were domesticated twice. The latest analysis also add weight to previous research that moves the timing of domestication back as far as 40,000 years ago. Everyone has their own idea about where and when dogs originated, says Krishna Veeramah, a palaeogeneticist at Stony Brook...

The 21st-century back-to-the-farm movement stems from our yearning to escape the artificiality of modern urban life. Yet the domesticated plants and animals now found in most gardens and farms are themselves artificial, the results of extensive human meddling, cross-breeding and genetic manipulation. Mankind began engineering what we now call “farm animals,” including cattle, all the way back in the Neolithic period, between 10,000 and 5,000 B.C. Try as you might, you won’t find an untamed Jersey cow that originated naturally in the wild, because no such thing exists — just like there’s no such thing as a wild labradoodle. Cattle...

Giant bull, wild boar and red deer bones left at a settlement a mile from Stonehenge prove that Amesbury is the oldest settlement in Britain and has been continually occupied since 8820 BC, according to archaeologists who say the giant monuments were built by indigenous hunters and homemakers rather than Neolithic new builders. Carbon dating of aurochs – a breed twice the size of bulls – predates the settlers responsible for the massive pine posts at Stonehenge, suggesting that people had first lived in Wiltshire around 3,000 years before the site was created in 3000 BC. Experts had previously thought...

Carbon dating from an archaeological dig by the university shows that the parish of Amesbury has been continually occupied for every millennia since 8,820BC. The origins of Amesbury have been discovered as a result of carbon dating bones of aurochs - twice the size of bulls, wild boar and red deer - following a dig at Vespasian's Camp, Blick Mead, a mile-and-a-half from Stonehenge. It dates the activities of the people who were responsible for building the first monuments at Stonehenge, made of massive pine posts, and show their communities continuing to work and live in the area for a...

In the 1970s, archaeologist Peter Bogucki was excavating a Stone Age site in the fertile plains of central Poland when he came across an assortment of odd artefacts. The people who had lived there around 7,000 years ago were among central Europe's first farmers, and they had left behind fragments of pottery dotted with tiny holes. It looked as though the coarse red clay had been baked while pierced with pieces of straw. Looking back through the archaeological literature, Bogucki found other examples of ancient perforated pottery. “They were so unusual — people would almost always include them in publications,”...

Archaeological researchers at the University of Groningen have discovered that the aurochs, the predecessor of our present-day cow, lived in the Netherlands for longer than originally assumed. Remains of bones recently retrieved from a horn core found in Holwerd (Friesland, Netherlands), show that the aurochs became extinct in around AD 600 and not in the fourth century. The last aurochs died in Poland in 1627... The aurochs was much larger than the common cows we know today, with aurochs bulls measuring between 160 and 180 cm at the withers, and aurochs cows between 140 and 150 cm. The cattle bred...

Scientists have analysed the DNA of ancient giant European wild cattle that died out almost 400 years ago. They have determined the first mitochondrial genome sequence from aurochs (Bos primigenius) from bone found in a cave in England. Mitochondrial DNA (mtDNA) is passed down from a mother to her offspring....... One of the researchers involved, Dr Ceiridwen Edwards, has previously investigated the remains of a polar bear found in the Scottish Highlands.... The species became extinct when a female animal died in a forest in Poland in 1627. Roman general and dictator Julius Caesar was said to have been impressed...

Aurochs were immortalised in prehistoric cave paintings and admired for their brute strength and "elephantine" size by Julius Caesar. But despite their having gone the way of the dodo and the woolly mammoth, there are plans to bring the giant animals back to life. The huge cattle with sweeping horns which once roamed the forests of Europe have not been seen for nearly 400 years. Now Italian scientists are hoping to use genetic expertise and selective breeding of modern-day wild cattle to recreate the fearsome beasts which weighed around 2,200lb and stood 6.5 feet at the shoulder. Breeds of large...

In modern society dogs are often referred to as "man's best friend" but according to an archaeological review early Aboriginal society sported a similar relationship between women and dingoes (Canis lupus dingo). The study by UWA and ANU suggests people formed close bonds with dingoes soon after the dogs' arrival on the mainland roughly 4000 years ago, with the dogs enabling women to contribute more hunted food. UWA archaeologist Jane Balme, who led the research, says it is thought the first dingoes arrived on watercraft with people from South East Asia. "What they're doing on the boat is not clear...

Dogs can copy each other's expressions in a split-second just like people, showing signs of basic empathy, according to Italian researchers. Mimicking each other's facial expressions is a human habit, which helps people to get along. Dogs do the same to bond with other dogs, scientists report in the journal, Royal Society Open Science. They think dogs may be showing a basic built-in form of empathy, enabling them to pick up on emotions. And the phenomenon may have emerged in our canine companions during the process of domestication, say scientists from the Natural History Museum, University of Pisa.

This week, millions of people around the world will no doubt experience rapid mimicry-an involuntary, split-second mirroring of another person's facial expressions-as they exchange smiles over gifts, good meals and holiday traditions. This phenomenon, observed in humans and many other primates, is considered a basic building block of our ability to feel empathy. "When your companion or friend smiles, you don't know why exactly, but you immediately react with the same smile to him or her," says Elisabetta Palagi, an evolutionary biologist at the University of Pisa in Italy. "It’s an extremely important phenomenon, because through this mimicry you can...
