Mammaliaforms encompass both living and extinct species that share a close relationship with mammals. Research on mammaliaforms aids scientists in deciphering the evolutionary developments responsible for various mammalian features.In two consecutive studies in Nature, Dr. Mao Fangyuan and Dr. Zhang Chi from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences, together with colleagues from Australia and the United States, recently reported two Jurassic mammaliaforms from China, revealing the earliest dental diversification, mandibular middle ears, and articular-quadrate joint transformation of mammaliaforms.The studies provide key information about the evolutionary shift from reptilian jaw bones to early...

There is no single answer to this puzzle. Dinosaurs dominated the planet for around 179 million years and during that time, evolved into an enormous array of different shapes and sizes. Some were tiny, like the diminutive Albinykus, which weighed under a kilogram (2.2lbs) and was probably less than 2ft (60cm) long. Others were among the biggest animals to have ever lived on land, such as the titanosaur Patagotitan mayorum, which may have weighed up to 72 tonnes. They ran on two legs, or plodded on four. And along with these diverse body shapes, they would have produced an equally...

Fossilized bone fragments unearthed in a cave in northern Spain in 2022 have revealed a previously unknown human population that lived more than 1.1 million years ago, according to new research.Found at the Sima del Elefante site in the Atapuerca Mountains, the fossils make up a partial skull comprised of the left side of the face of an adult hominin. The mineralized bones are the earliest human fossil remains found so far in Western Europe.However, it wasn't immediately obvious which species of prehistoric human the team had found, and the study describing the fossils, published Wednesday in the journal Nature,...

I was asked this week how I can be a Christian and support Donald Trump throwing out thousands of illegal aliens. But one of the toughest things about being a Christian is trying to be a citizen. No — scratch that. I mean trying to be a good citizen. Saint Paul was a citizen, too, but I don’t think he cared a bit about the Roman Empire. He gave the impression that if the Gauls invaded tomorrow, he would just shrug his shoulders and try to baptize them, too. And although he was the polar opposite of Thomas Paine in...

Approximately 14,000 years ago, the unprecedented solar event—now judged to be the most powerful known to have occurred—marked Earth’s transition into the Holocene epoch, according to the findings of an international team of scientists. The team traces the event to around 12,350 BC using a new climate-chemistry model specifically designed to reconstruct ancient solar particle activity. This expands the known timeline for ancient solar storms and raises the bar on the upper boundaries of their intensity. Although the event in question was already known from past observations of radiocarbon spikes in ancient wood samples, its scale and magnitude remained unknown....

The Aztec Empire once hosted an expansive trade network that brought volcanic glass to its capital from right across Mesoamerica, coast to coast. The largest compositional study of obsidian artifacts found in the ancient Aztec capital of Tenochtitlan has now revealed the far-flung influence of the Mexica culture – the largest and most powerful faction of the Aztec Alliance. The 788 precious obsidian objects analyzed include weapons, urns, earrings, pendants, scepters, and decorated human skulls. They appear to have been sourced from across the Trans-Mexican Volcanic Belt, even from the lands of rival governments. The discovery speaks to the commercial...

Recreating the spectacular pose many dinosaurs adopted in death might involve following the simplest of instructions: just add water. When palaeontologists are lucky enough to find a complete dinosaur skeleton – whether it be a tiny Sinosauropteryx or an enormous Apatosaurus – there's a good chance it will be found with its head thrown backwards and its tail arched upwards – technically known as the opisthotonic death pose. No one is entirely sure why this posture is so common, but Alicia Cutler and colleagues from Brigham Young University in Provo, Utah, think it all comes down to a dip in...

Some of the largest animals to ever walk on Earth were the long-necked, long-tailed dinosaurs known as the sauropods—and the most famous of these giants is probably Brontosaurus, the "thunder lizard." Deeply rooted as this titan is in the popular imagination, however, for more than a century scientists thought it never existed. The first of the Brontosaurus genus was named in 1879 by famed paleontologist Othniel Charles Marsh. The specimen still stands on display in the Great Hall of Yale's Peabody Museum of Natural History. In 1903, however, paleontologist Elmer Riggs found that Brontosaurus was apparently the same as the...

Did apes descend from us? Skeleton of Ardi, 1.2-metre, 50-kilogram female may hold the clue Joseph Hall Science writer It may well be the closest we will ever come to the missing link between chimps and humans and the most important anthropological find ever. In a series of studies released today by the journal Science, researchers have revealed a creature that took the first upright steps toward human beings and fundamentally changes the way we look at our earliest evolutionary ancestors. The research brings into question the belief that our most distant ancestors descended from apes. What's closer to the...

Conceptual image depicting end of the universe by generative AI (© The 2R Artificiality - stock.adobe.com) In a nutshell * Scientists discovered that neutron stars and white dwarfs are slowly evaporating, shortening the universe’s expected lifespan from 10^1100 years to 10^78 years. * All massive objects lose energy through a process similar to how black holes evaporate, with denser objects deteriorating faster. Despite this “earlier” end, the universe’s death is still inconceivably far in the future—neutron stars will last 10^68 years and white dwarfs about 10^78 years. ================================================================================ NIJMEGEN, Netherlands — Scientists have just calculated that our universe will end...

Scientists have been wondering for years which dinosaur could run the fastest. Now, new simulation models are offering a fresh look at dinosaur speed. This renewed interest has roots in a major discovery from 1964, when paleontologist John Ostrom and his team uncovered Deinonychus—a dinosaur with a lightweight body, long claws, and strong legs. Its features challenged the long-held image of dinosaurs as sluggish reptiles and instead pointed to an active, fast-moving predator. This discovery helped launch what scientists call the “dinosaur renaissance,” a major shift in how experts understood dinosaur behavior. Instead of slow-moving reptiles, some dinosaurs began to...

Have you ever wondered why you don't have thick hair covering your whole body like a dog, cat or gorilla does? Humans aren't the only mammals with sparse hair. Elephants, rhinos and naked mole rats also have very little hair. It's true for some marine mammals, such as whales and dolphins, too. Scientists think the earliest mammals, which lived at the time of the dinosaurs, were quite hairy. But over hundreds of millions of years, a small handful of mammals, including humans, evolved to have less hair. What's the advantage of not growing your own fur coat? I'm a biologist...

Humans are the only mammals with long hair on their heads. Scientists look into what drives this unique feature. Humans evolved long hair on their head to prevent overheating and excess water loss when walking under the hot sun in Africa. iStock, Delmaine Donson In 2004, a Chinese woman named Xie Qiuping won the Guinness World Record for the longest human scalp hair at 5.627 meters—the length of an adult male giraffe! While this is an anomaly, humans are the only mammals that have negligible body hair, but extremely long hair on their heads. “It's such an important part of...

Earth's Northern Lights typically dance near the poles, but 41,000 years ago, they lit up skies over North Africa and Australia. New research reveals how dramatically Earth's magnetic field weakened and shifted during an event called the Laschamps geomagnetic excursion, potentially influencing human evolution at a pivotal moment in our history...During the Laschamps excursion, Earth's magnetic field weakened to just 10% of its current strength, while the magnetic poles shifted dramatically away from the geographic poles...Using advanced computer modeling, the research team reconstructed Earth's magnetosphere during five key periods of the excursion. At its peak around 40,977 years ago, Earth's...

Every Easter, children and adults alike eagerly search for colorful eggs hidden by the Easter Bunny on Sunday morning. Whether made of chocolate, painted with bright designs, or stuffed with little surprises, Easter eggs are a beloved tradition that bring so much joy to the beloved holiday. But have you ever stopped to wonder where this quirky custom comes from? Why do we associate eggs with Easter, and how did this tradition evolve from old rituals to the modern-day candy-fueled extravaganza we know and love? The answer is as layered as a perfectly decorated egg.

Researchers analyzed the ancient DNA of two mummies from what is now Libya to learn about people who lived in the "Green Sahara" 7,000 years ago. Naturally mummified human remains found in the Takarkori rock shelter in the Sahara desert point to a previously unknown human population. (Image credit: © Archaeological Mission in the Sahara, Sapienza University of Rome) Two 7,000-year-old mummies belong to a previously unknown human lineage that remained isolated in North Africa for thousands of years, a new study finds. The mummies are the remains of women who once lived in the "Green Sahara," also known as...

Recent research by a multidisciplinary team of archaeologists and geologists has revealed that the Eridu region of southern Mesopotamia, inhabited from the sixth to the first millennium BCE, boasts one of the oldest and most well-preserved irrigation networks.Led by geoarchaeologist Jaafar Jotheri from Durham University, the research team uncovered an extensive water management system that predates the first millennium BC, offering valuable insights into the irrigation practices of ancient farmers.The Eridu region of southern Mesopotamia, located in present-day Iraq, is one of the best-preserved ancient archaeological sites, having been occupied from the sixth until the early first millennium BC. While...

A group of over 100 Christian pastors and social justice activists have signed an open letter denouncing the Trump administration's cuts to welfare programs, foreign aid and large-scale deportations of immigrants in the country illegally. Titled "Returning To Jesus: Practicing Lent In Our Time," the letter was the result of meetings among faith organization leaders in January, with the Center on Faith and Justice at Georgetown University, headed by longtime Evangelical progressive activist Jim Wallis, helping organize signatures and other logistics. The letter does not mention President Donald Trump by name, though it does take issue with the current efforts...
