☆ The real Paleo diet was heavy on plants with very little meat, according to a study of early human remains
▼ + stars: | 2024-01-24 | by ( Marianne Guenot | ) www.businessinsider.com time to read: +6 min

Read previewThe popular Paleo diet is based on the belief that we are better off eating like our ancestors by sticking to a largely meat-heavy diet. "One way to think about it is as soon as anybody tells you that the Paleo diet was one thing, you can stop listening," said Pontzer, who wasn't involved in the study. The paleo diet is a high-protein diet that emphasizes unprocessed foods. AdvertisementThere is no one Paleo dietThis isn't the only research that disproves the model often held up by proponents of the modern-day definition of the Paleo diet. What's clear is that a meat-heavy diet isn't reflective of what people ate thousands of years ago.

The footprints, found at several sites in southern Africa, were recently identified as the oldest birdlike tracks ever found, preceding the earliest known skeletal fossils of avians by about 60 million years. Some called the tracks birdlike, but others weren’t so sure. Ellenberger may have muddied the waters by assigning many differently shaped tracks to the ichnogenus, “and not all of them are birdlike,” Abrahams said. They could belong to other reptiles or cousins of dinosaurs that evolved birdlike feet,” Clarke said. During a trip to Maphutseng, a fossil locale in Lesotho, the team found a number of birdlike tracks from the Triassic Period.

That’s what scientists have interpreted from the pose of the dinosaur’s fossil skeleton. The study authors identified it as an alvarezsaurid, a type of small theropod (bipedal meat-eating dinosaur) with a long tail and legs and short front limbs. Alvarezsaurids are part of a larger dinosaur group called maniraptorans, which includes birds and birdlike dinosaurs that were their closest relatives.

☆ How head lice reveal secrets about human origins

CNN —Head lice have been constant, if unwanted, human companions for as long as our species has been around. Some 20 years ago, David Reed, a coauthor of the new study and a researcher and curator at the Florida Museum of Natural History, found that human head lice are composed of two ancient lineages, with origins predating Homo sapiens. Doing so allowed researchers to detect the hybrid lice and better capture the genetic diversity of head lice. Ascunce said she had hoped the information they gleaned might answer whether Neanderthal head lice are still around today, but the 15 genetic markers, known as “microsatellites,” that they studied in the lice nuclear DNA didn’t reveal that information. “New ongoing studies are being done using whole genome sequences from human lice, so stay tuned for more exciting research on that.”

☆ One-fifth of Europe’s Red List species face risk of extinction, new analysis finds
▼ + stars: | 2023-11-08 | by ( Manav Tanneeru | Taylor Nicioli | ) edition.cnn.com time to read: +5 min

CNN —Of all 14,669 varieties of plants and animals found in Europe that were registered on the International Union for Conservation of Nature’s Red List of Threatened Species by the end of 2020, one-fifth of them face the risk of extinction, a new analysis has found. The thousands of species found in Europe that appear on the Red List account for nearly 10% of the continent’s total biodiversity, according to the paper. IPBES originally estimated that 1 million plant and animal species across the world were at risk of extinction, including about half a million insect varieties, based on inferences from Red List data. The data on invertebrates provided by the new analysis suggests the number of species threatened with extinction globally is actually closer to 2 million, Hochkirch said. Hochkirch said he hopes the analysis will spur further conservation action for insects and other threatened species in Europe.

“They are way smarter than you think,” Ms. Hillemacher said. Now, in a study published in the journal PLOS One on Wednesday, Ms. Hillemacher and her colleagues say they have found evidence that roosters can recognize themselves in mirrors. The mirror test is a common, but contested, test of self-awareness. The mirror test has since been used to assess self-recognition in many other species. But different cognitive processes are active in different situations, and there’s no reason to think that the mirror test is accurate for animals with vastly different sensory abilities and social systems than what chimps have.

The scientists found large whales such as humpbacks and North Atlantic right whales were among the most vulnerable to climate change, and that other toothed whales and dolphins were also at high risk. The scientists looked at the animals' degree of exposure to climate change and sensitivity and capacity to adapt to it. “The U.S. is one of the most data-rich countries when it comes to marine mammals, and those data should be driving what are arguably some of the world’s strongest laws to protect marine mammals," she said. But the way climate change affects the giant animals is global in nature, so the broader approach is helpful, she said. Climate change also could affect the distribution and behavior of marine mammals, the study states.

The study published Wednesday in PLOS One found that there are four genes associated with how well someone is able to adhere to a vegetarian lifestyle. Several of the genes that the study found to be associated with vegetarianism had to do with metabolizing lipids, Yaseen said. Although this study may not provide a definitive answer, it is an important look into nutrition, he said. “This study shines a light on a relatively under-explored area of research: the genetics behind dietary preferences,” Ordovás said. “The association of genetic variants with long-term strict vegetarianism suggests a biological basis for this dietary choice, beyond just cultural, ethical, or environmental reasons.”

CNN —Researchers working at a cave in southern Spain have found evidence that the skeletal remains of ancient humans buried there were dug up, modified and even used as tools by subsequent generations. While these types of remains are known as “skull cups,” that doesn’t necessarily mean they were used as containers, Milella said. “Modification and manipulation of human remains are indeed well known for this time, with examples also from the same region. In that sense, Marmoles Cave is consistent with what we know about the funerary behavior of these cultures,” he said. And it is also possible that those who modified the remains may have known the people that they belonged to when they were alive.

"The actions of fragmenting and manipulating the bones may well be related to specific ritual events performed inside the cave," Martínez Sánchez said. "They're often viewed as sort of passageways to another world to the ancestors, to other kinds of worlds that are seen as sacred liminal spaces, spaces that are somewhere in between the land and the living and the land of the ancestors," she said. There's a chance they may have disturbed the human remains as well.

CNN —Modified skulls found in an ancient burial site in Japan were deliberately reshaped in both men and women as an expression of collective identity. It’s possible, the researchers suggested, that the Hirota cranial reshaping played a part in their trading success. For the new study, the scientists 3D-scanned and digitally modeled 19 adult Hirota skulls to conduct more detailed morphological analysis. Certain indentations were also identified in Hirota skulls but were absent in those of Jomon and Doigahama individuals. At the Hirota site, each marker indicates where burials were found along with the notes on their sex and approximate age group.

Researchers didn’t find the parasites in phytosaur bones or teeth; rather, they retrieved them from a nugget of fossilized feces, known as a coprolite. For example, certain fish with spiraling intestines poop out what eventually become spiral-shaped coprolites, according to Nonsrirach. “Studying the remains of parasites in coprolites is important since it provides us with rare insights into ancient parasite-host relationships,” Qvarnström said. “This event raises interesting questions about how prey animals and parasites interact with each other. It suggests that parasites may have been inside the bodies of prey before they were eaten,” Nonsrirach said.

Few complete fossils of this Jurassic sea turtle, named Solnhofia parsonsi, have been discovered. Today’s marine turtle species all have elongated, rigid flippers to propel them through the ocean depths. But the newly described fossil’s limbs were stumpier than those of modern sea turtles relative to its body size. An artistic reconstruction shows the extinct sea turtle in its coastal marine environment. The newly described fossil presents a far more complete view of those limbs, showing that they differed dramatically from the extremities of sea turtles alive today.

The area’s latest find is a beautifully preserved — if pancaked — turtle. Described in an article published Wednesday in the journal PLOS One, the specimen represents an approach to marine life unlike that of any shelled reptile today. The turtle’s name is Solnhofia, said Felix Augustin, a paleontologist at the University of Tübingen in Germany and an author of the study. Originally named in 1975, for decades the creature was known only from a pair of skulls found in Bavaria and Switzerland.

☆ Saber-Tooth Cats and Dire Wolves Carried a Terrible Disease in Their Bones
▼ + stars: | 2023-07-12 | by ( Miriam Fauzia | ) www.nytimes.com time to read: +1 min

Some 50,000 to 10,000 years ago as ice sheets melted and the planet warmed, around 100 species of gigantic animals started to disappear without a trace. Paleontologists have sought to understand exactly how these animals died off, including iconic predators like the saber-tooth cat and the dire wolf. Some hypotheses suggest stiff competition for limited food aggravated by the arrival of humans and gray wolves. But new evidence suggests a bone disease that can debilitate modern cats and dogs, and even some of their humans, may have also played a role. In a paper published Wednesday in the journal PLoS One, researchers report that as the climate shifted, the bones of saber-tooth cats and dire wolves became riddled with defects associated with osteochondrosis dissecans, or OCD, a severe developmental disease where holes form in bone caused by developing tissue that never hardened.
