Apr. 7, 2023 —A team of researchers compared the genomes of woolly mammoths with modern day elephants to find out what made woolly mammoths unique, both as individuals and as a species. The investigators report ...
Mar. 21, 2023 —A new study investigates how an extinct, carnivorous marsupial relative with canines so large they extended across the top of its skull could hunt effectively despite having wide-set eyes, like a cow ...
Feb. 28, 2023 —A review of evidence from prior research provides new support for the possibility that the evolution of larger brains in some species was enabled through increased energy investment by parents in ...
Jan. 12, 2023 —A study is providing a glimpse into dinosaur and bird diversity in Patagonia during the Late Cretaceous, just before the non-avian dinosaurs went extinct. The fossils represent the first record of ...
Jan. 4, 2023 —Orangutans, mice, and horses are covered with it, but humans aren't. Why we have significantly less body hair than most other mammals has long remained a mystery. But a first-of-its-kind ...
Dec. 21, 2022 —Microraptor was an opportunistic predator, feeding on fish, birds, lizards -- and now small mammals. The discovery of a rare fossil reveals the creature was a generalist carnivore in the ancient ...
Dec. 14, 2022 —Sediment cores obtained from Eifel maar sites provide insight into the presence of large Ice Age mammals in Central Europe over the past 60,000 years: Overkill hypothesis not confirmed. Herds of ...
Dec. 12, 2022 —While the Diprotodon -- the extinct megafauna species that is distantly related to wombats but was the size of a small car -- is commonly (but incorrectly) thought of as Australia's 'giant ...
Dec. 8, 2022 —Researchers have tested the biting efficiency of Smilodon, an extinct species of carnivore close to the extant felines. Using high-precision 3D scans and simulation methods, the team has just ...
Dec. 7, 2022 —Dinosaurs dominated the world right up until a deadly asteroid hit the earth, leading to their mass extinction, some 66 million years ago, a landmark study reveals. Fresh insights into ...
Nov. 30, 2022 —Paleontologists say environmental DNA is not always helpful in identifying when animals like mammoths went extinct because genetic material found in sediment could have come from animals that died ...
Nov. 28, 2022 —A new study compiles data on more than 3,000 species to show how climate and geologic changes across Asia over the last 66 million years have shaped the evolution of the continent's ...
Oct. 11, 2022 —Today, increasing levels of carbon dioxide in the atmosphere are warming up the planet. Climate change can disrupt the balance of ecosystems and contribute to endangerment and extinction of some ...
Oct. 7, 2022 —A giant kangaroo that once roamed on four legs through remote forests in the Papua New Guinea Highlands may have survived as recently as 20,000 years ago -- long after large-bodied megafauna on ...
Sep. 28, 2022 —An international team has reconstructed the genome organization of the earliest common ancestor of all mammals. The reconstructed ancestral genome could help in understanding the evolution of mammals ...
Sep. 2, 2022 —Did the first ancestors of whales pick up where the mosasaurs left off 66 million years ago, after the extinction of all the large predatory marine reptiles? A study has looked into the possible ...
Aug. 29, 2022 —Approximately 13.5 million years ago, north-west Queensland was home to an unusual and particularly tiny species of crocodile and now scientists are unlocking its ...
Aug. 23, 2022 —To investigate whether paleoclimatic temperature shifts are correlated with body size changes, biologists decided to test this hypothesis using tetraodontiform fishes as a model ...
Aug. 10, 2022 —A new study shows that 87 genes have been affected by deletions or short insertions during the course of the mammoth's evolution. The researchers note that their findings have implications for ...
Aug. 9, 2022 —Researchers successfully captured CT images of an entire woolly mammoth tusk. Researchers were able to do a full scan of the tusk in its entirety -- or in toto -- using a newer clinical CT scanner. ...
