Human communities in the Levant at this time were known as Natufian. They were primarily hunters and foragers and are considered the first non-nomadic society; the semi-sedentary habits of Natufian culture were likely a precursor to humans settling down and becoming farmers. At the el-Wad Terrace settlement, the site was densely layered with animal remains, of which "a high percentage" belonged to lizards and snakes, the researchers reported in a new study, published online June 10 in the journal Scientific Reports. The quantity of squamate bones at the site was astonishing; that alone hinted at human consumption as a possible...

From The TimesNorman Hammond, Archaeology Correspondent March 24, 2008 The lowly sweet potato may unlock America’s past How the root vegetable found it's way across the Pacific One of the enduring mysteries of world history is whether the Americas had any contact with the Old World before Columbus, apart from the brief Viking settlement in Newfoundland. Many aspects of higher civilisation in the New World, from the invention of pottery to the building of pyramids, have been ascribed to European, Asian or African voyagers, but none has stood up to scrutiny. The one convincing piece of evidence for pre-Hispanic contact...

Artist's reconstruction of the world's oldest modern bird, Asteriornis maastrichtensis, in its original environment. 66.7 million years ago parts of Belgium were covered by a shallow sea, and conditions were similar to modern tropical beaches like The Bahamas. Asteriornis lived at the end of the Age of Dinosaurs, a time when mosasaurs (giant marine reptiles) swam in the oceans, and Tyrannosaurus rex lived on land. Asteriornis had fairly long legs and may have prowled the tropical shoreline.

On paper, Toxoplasma gondii looks as if it ought to be the most famous parasite on earth. This single-celled pathogen infects over half the world's population, including an estimated 50 million Americans. Each of Toxoplasma's victims carries thousands of the parasites, many residing in the brain. As if that were not enough of an accomplishment, Toxoplasma is equally adept at infecting all other warm-blooded animals, as disparate as chickens and kangaroos. Scientists are now discovering some of the secrets of Toxoplasma's success. Researchers in Sweden report that the parasite fans out through the body by manipulating mobile cells that are...

Los Angeles, Oct. 30, 2002 - Scientists from the Keck School of Medicine of the University of Southern California have, for the first time, shown experimentally the steps in the origin and development of feathers, using the techniques of molecular biology. Their findings will have implications for the study of the morphogenesis of various epithelial organs-from hairs to lung tissue to mammary glands-and is already shedding light on the controversy over the evolution of dinosaur scales into avian feathers.

WASHINGTON (AFP) – Eating less meat will not reduce global warming, and claims that it will distract from efforts to find real solutions to climate change, a leading air quality expert said Monday. "We certainly can reduce our greenhouse gas production, but not by consuming less meat and milk," Frank Mitloehner, an air quality expert at the University of California-Davis, said as he presented a report on meat-eating and climate change at a conference of the American Chemical Society in California. Blaming cows and pigs for climate change is scientifically inaccurate, said Mitloehner, dismissing several reports, including one issued in...

I’m wondering, since this BLM movement seems to have gained the upper hand in the US, before extra-governmental groups begin going to rural areas and demanding White owners give up their farms and. Businesses. It happened in South Africa, I believe it’s just a matter of time.

Microscopic signatures of malting could help reveal which prehistoric people had a taste for beer. Ancient beer is difficult to trace, because many of beer’s chemical ingredients, like alcohol, don’t preserve well (SN: 9/28/04). But a new analysis of modern and ancient malted grain indicates that malting’s effects on grain cell structure can last millennia. This microscopic evidence could help fill in the archaeological record of beer consumption, providing insight into the social, ritual and dietary roles this drink played in prehistoric cultures, researchers report online May 7 in PLOS ONE. Malting, the first step in brewing beer, erodes cell...

At some point in the past two millennia — peanuts on an evolutionary time scale — humans transformed their horses into equine speed demons. Selective breeding had a price, though, beyond $30,000 vials of pedigreed racehorse sperm. Unhelpful mutations plagued the animals. The current population of domesticated horses is about 55 million, but at some point in their history, their genetic diversity crashed. The Y chromosomes of all the world's stallions are now quite similar, suggesting that only a relatively few males were the ancestors of today's horses. Humans have not always bred so selectively, according to a study published...

...Prof. Haak will also try to detect more plague DNA in hundreds of skeletons from the late Neolithic and early Bronze Age. So far, DNA evidence from a dozen skeletons points to little variability between the strains of Yersinia pestis in such remains, suggesting that the pestilence spread rapidly across the continent. The speed may owe to another human advance at this time -- the domestication of wild horses, which may literally have carried the disease into Europe. "We see the change from wild local horses to domesticated horses, which happened rapidly at the beginning of the Bronze Age," said...

An international team of scientists led by the University of Adelaide's Davies Research Centre has shown that it is possible to disentangle the DNA sequences of the chromosomes inherited from the mother and the father, to create true diploid genomes from a single individual. In a report published in Nature Communications, and funded by the Davies Research Centre over the past 15 years, the researchers have shown that genomes of two important modern-day cattle breeds, Angus (Bos taurus taurus) and Brahman (Bos taurus indicus), can be completely decoded from a single hybrid individual carrying the genetics of both breeds, using...

Neanderthals selected rib bones from specific animals to make the lissoirs (French for 'smoothers'), which are bone tools that have been intentionally shaped and used on animal hides to make them softer and more water resistant, according to new research led by paleoanthropologists from the University of California, Davis. Scientists know that some Neanderthals produced bone tools. These include the discovery of five nearly identical fragments of lissoirs from two Paleolithic sites in southwest France: Pech-de-l'Azé I (Pech I) and Abri Peyrony. These specialized tools are often worn so smooth that it's impossible to tell which animal they came from...

It is perhaps best-known for its hipsters, but long before Shoreditch became avant garde, it was a place of agriculture and farmers according to evidence from a radiocarbon dating technique that has revealed details about Neolithic London. The technique proved that the most significant early Neolithic pottery discovered in London is 5,500 years old. It reveals for the first time that the city's prehistoric inhabitants led a less mobile, farming-based lifestyle than their hunter-gathering forebears. The research, published in Nature, reveals that an area around Shoreditch High Street was once populated by farmers herding their livestock across a once-green landscape....

An international team found that during this period, crops were being cultivated in a remote location in what is now northern Bolivia. The scientists believe that the humans who lived here were planting squash, cassava and maize. The inhabitants also created thousands of artificial islands in the forest. The end of the last ice age, around 12,000 years ago, saw a sustained rise in global temperatures... Researchers have previously unearthed evidence that crops were domesticated at four important locations around the world. So China saw the cultivation of rice, while in the Middle East it was grains, in Central America...

In 2015, researchers reported that cod caught off the North American coast around 6,500 years ago by Stone Age hunter-gatherers contained more than 20 times the levels of mercury recommended for humans today... They analyzed the chemical composition of bones of animals, like Atlantic cod and harp seals, disposed of in ancient garbage pits, and so preserved to this day. Both species were among the main ingredients in the diet of the local people, even if the early hunter-gatherers, based on cut marks found on the bones, also successfully hunted for haddock, whale, dolphin, reindeer and beaver. The analyzed bones...

In the increasingly urbanized world, few people still ride horses for reasons beyond sport or leisure. However, on horseback, people, goods and ideas moved across vast distances, shaping the power structures and social systems of the premechanized era. From the trade routes of the Silk Road or the great Mongol Empire to the equestrian nations of the American Great Plains, horses were the engines of the ancient world. Where, when and how did humans first domesticate horses? Tracing the origins of horse domestication in the prehistoric era has proven to be an exceedingly difficult task. Horses -- and the people...

Israeli researchers revealed Wednesday that they successfully grew extinct date plants from ancient seeds found at archaeological sites in the Judean Desert. Dozens of seeds were gleaned from archaeology collections gathered at locations in the dry Dead Sea area, including the Masada hilltop fortress built by King Herod the Great in the first century BCE and the ancient site of Qumran, famous for the discovery of the Dead Sea Scrolls in the 1940s. Six saplings grew from 32 seeds sown and the plants have been dubbed Adam, Jonah, Uriel, Boaz, Judith, and Hannah... Radiocarbon dating revealed the seeds used for...

Cats like to act like they rule roost – as anyone who lives with one will tell you. And now scientists have found that it really is the cat, and certainly not the owner, who is responsible for harmony in the home. Experts at the University of Lincoln have discovered cats are the 'key player' in maintaining good karma when its sworn enemy, a dog, is brought into the household. For although they may be descended from wolves, with big, loud barks and fearsome teeth, dogs are likely to find themselves bullied mercilessly if they live with a cat.

Sometime around the invention of agriculture, the cats came crawling. It was mice and rats, probably, that attracted the wild felines. The rats came because of stores of grain, made possible by human agriculture. And so cats and humans began their millennia-long coexistence. This relationship has been good for us of course—formerly because cats caught the disease-carrying pests stealing our food and presently because cleaning up their hairballs somehow gives purpose to our modern lives. But this relationship has been great for cats as species, too. From their native home in the Middle East, the first tamed cats followed humans...

Goats Form Intense Connections with Humans, Too It's the first time a creature raised for food has evolved intense, meaningful connections with people. Photo: A goat relaxes at the Buttercups Sanctuary for Goats, United Kingdom. Credit: Christian Nawroth Goats have surprisingly just been added to the very short list of animals that are known to communicate in very direct and complex ways with humans. The other two animals, dogs and horses, are often raised as companions to humans, so the goat findings -- reported in the journal Royal Society Biology Letters -- mark the first time that an animal...
