Woolly mammoths were likely butchered by hunters and gatherers, study finds

A woolly mammoth lay for thousands of years in wet ground near the Danube, its ribs, foot bones, and a nearly 2.5-meter tusk sealed in place until construction crews in Bavaria uncovered them by chance. What looked at first like a remarkable Ice Age fossil soon turned into something rarer. It became direct evidence that people handled the carcass during one of the coldest and harshest chapters of the last glacial period. The partial skeleton was found at Taimering, near Regensburg in southern Germany, during excavations that had originally been aimed at medieval remains. Instead, workers and archaeologists recovered a large mammoth tusk and more than 70 bones and fragments. Most of them were ribs and bones from the hands and feet. The surfaces were preserved with unusual clarity because they had spent millennia in waterlogged sediments. “The mammoth’s tusk and bones were exceptionally well-preserved due to their millennia-long conservation in the wet soil environment,” says Dr. Christoph Steinmann, deputy head of the Department of Archaeological Heritage Preservation for Lower Bavaria/Upper Palatinate at the BLfD. …

“The Sheep Detectives” cloaks an urgent message in woolly clothing

“The Sheep Detectives” cloaks an urgent message in woolly clothing

In any coziness competition, if such contests exist, fleece is tough to beat. It offers a fluffy kind of camouflage when you want to hide from the world’s troubles. That should make the allure of “The Sheep Detectives” obvious at first glance. Sheep might as well be harmless, earth-bound clouds. Just about everyone loves them, and just about everybody loves a cozy murder mystery. What could be cozier than a flock of charismatic sheep hunting their shepherd’s killer? “The Sheep Detectives” is both a powerful story about mourning and a warning against the peril of mindwiping inconvenient histories. Even if you don’t buy into the notion that sheep, of all creatures great and small, could possibly have the brainpower to crack a murder case, a movie like this is exactly what we need in these ungentle days. Animal heroes? Check. Bumbling humans? There’s a whole English hamlet full of them. The only two legs worth standing beside is George Hardy (Hugh Jackman), who tends to his flock like an attentive father looking after his children. …

We’re still recovering from losing the woolly mammoth

We’re still recovering from losing the woolly mammoth

Get the Popular Science daily newsletter💡 Breakthroughs, discoveries, and DIY tips sent six days a week. There’s a gaping 2,000-pound hole in Earth’s food web. Saber-toothed cats with 7-inch-long fangs, sloths the size of elephants, wombats the size of cars, and many of the world’s largest mammals disappeared between 50,000 and 10,000 years ago. While 10,000 years may seem long ago to humans, that’s a blink of an eye in evolutionary  time, and the disappearance of these megafauna still impacts us today. of.  According to a study published in the journal Proceedings of the National Academy of Sciences (PNAS), disappearing megafauna fundamentally reshaped the food web for modern animals. These effects are also more pronounced in North and South Americas than in other continents. The world’s food webs all have the same basic principle—animals that eat are then eaten by others. When an animal goes extinct, the complex web of relationships shifts among the surviving species. If a predator disappears, their prey’s population may go unchecked, with a series of cascading effects. Based on previous …

RNA from mummified woolly mammoth is the oldest ever recovered

RNA from mummified woolly mammoth is the oldest ever recovered

biologist: A scientist involved in the study of living things. cell: (in biology) The smallest structural and functional unit of an organism. Typically too small to see with the unaided eye, it consists of a watery fluid surrounded by a membrane or wall. Depending on their size, animals are made of anywhere from thousands to trillions of cells. Most organisms, such as yeasts, molds, bacteria and some algae, are composed of only one cell.  colleague: Someone who works with another; a co-worker or team member. degrade: To break down into smaller, simpler materials — as when wood rots or as a flag that’s left outdoors in the weather will fray, fade and fall apart. (in chemistry) To break down a compound into smaller components. DNA: (short for deoxyribonucleic acid) A long, double-stranded and spiral-shaped molecule inside most living cells that carries genetic instructions. It is built on a backbone of phosphorus, oxygen, and carbon atoms. In all living things, from plants and animals to microbes, these instructions tell cells which molecules to make. focus: (in …

Scientists recover genome from woolly rhino eaten by Ice Age wolf

Scientists recover genome from woolly rhino eaten by Ice Age wolf

Jan 14 : About 14,400 years ago, a weeks-old wolf puppy ate its last meal – meat from a woolly rhinoceros – shortly before dying on the harsh Ice Age landscape of northeastern Siberia. In a first, researchers have extracted DNA and recovered the rhino’s genome from a chunk of undigested meat from the stomach contents found in the puppy’s remains, discovered in permafrost near the village of Tumat. These genome findings provided insight into the fate of this impressive cold-adapted horned herbivore species once common in northern Europe and Asia. The researchers compared this rhino’s genome to those of two other individuals from the same species that lived thousands of years earlier – about 18,000 and 49,000 years ago – to examine genetic changes over time. In doing so, they learned that the woolly rhinoceros as a species remained genetically healthy until the end of the Ice Age before apparently suffering a rapid population collapse, probably because the warming climate erased their preferred steppe-tundra environment. For instance, the newly recovered genome showed no evidence …

DNA from wolf pup’s last meal reveals new facts about woolly rhino’s extinction

DNA from wolf pup’s last meal reveals new facts about woolly rhino’s extinction

The woolly rhino, Coelodonta antiquitatis, would have been an impressive sight to the ancient people who painted images of them on cave walls and carved figurines of them out of bone, antler, ivory and wood. The sadly now extinct rhino lived on the steppes and tundra of Europe and Asia, living alongside people for thousands of years. And a new study of woolly rhino DNA, extracted from the stomach of a wolf challenges a long held belief about species at risk of extinction. The species, which evolved in the middle of the Pleistocene era, approximately half a million years ago, weighed up to three tonnes. It was similar in size to the two largest rhino species alive today, the white rhino of southern and eastern Africa and the one-horned rhino of India. The woolly rhino was well adapted to live in ice age conditions. It had a thick layer of fat below the skin, a warm, woolly fleece and small ears and tail to minimise heat loss. It also had a shoulder hump to store …

Woolly rhino genome recovered from meat in frozen wolf pup’s stomach

Woolly rhino genome recovered from meat in frozen wolf pup’s stomach

The woolly rhino was one of the icons of the last glacial period The History Collection / Alamy A genome reconstructed from a tiny piece of flesh found in the stomach of a wolf pup that died 14,400 years ago suggests that woolly rhinos were still genetically healthy even as they faced imminent extinction. No one will ever know how a young female wolf pup died at a site near what is now the town of Tumat in northern Siberia, Russia. But it is most likely that she and her sister, together known as the Tumat Puppies, had just been fed the meat of a woolly rhinoceros (Coelodonta antiquitatis) by their mother when their den collapsed, entombing the siblings in permafrost for 14,400 years. The first of the puppies was found at the site in 2011 and the second in 2015. A dissection of the stomach contents of one of the puppies yielded a piece of woolly rhinoceros flesh. Edana Lord at Stockholm University in Sweden, a member of the team that studied the fragment, …

14,000-year-old woolly rhinoceros DNA extracted from wolf’s stomach

14,000-year-old woolly rhinoceros DNA extracted from wolf’s stomach

Get the Popular Science daily newsletter💡 Breakthroughs, discoveries, and DIY tips sent six days a week. Towards the end of the last ice age, an ancient wolf feasted on a young woolly rhinoceros (Coelodonta antiquitatis). When the wolf died, it ended up buried in Siberian permafrost for about 14,000 years until it was uncovered by paleontologists in 2015. Luckily for scientists, some woolly rhinoceros tissue remained inside of the wolf’s stomach. Now, these genetic detectives analyzed the woolly rhino’s genome and found that the species likely went extinct due to rapid population collapse and not a slow decline as Earth’s climate warmed. The findings are detailed in a study published today in the journal Genome Biology and Evolution. “Sequencing the entire genome of an Ice Age animal found in the stomach of another animal has never been done before,” Camilo Chacón-Duque, a study co-author and paleogenomicist at Stockholm University in Sweden, said in a statement. “Recovering genomes from individuals that lived right before extinction is challenging, but it can provide important clues on what caused …
