Mammoths suffered from diseases that are typical for people – HeritageDaily. Our earliest mammalian ancestors likely skulked through the dark, using their powerful night-time vision to find food and avoid reptilian predators that hunted by day.
This conclusion, published by Stanford researchers April 21 in Scientific Reports, used genetic data to support existing fossil evidence suggesting that our distant relatives may have adapted to life in the dark. The team, led by Liz Hadly, professor of biology and senior author on the paper, examined genes involved in night vision in animals throughout the evolutionary tree, looking for places where those genes became enhanced. “This method is like using the genome as a fossil record, and with it we’ve shown when genes involved in night vision appear,” Hadly said. 70mn yo dinosaur eggs with embryos inside unearthed in Argentina. Archaeologists in Argentina have announced the discovery of several dinosaur eggs – believed to be nearly 70 million years old and with the remainders of its embryos.
The eggs were found several years ago at a site called Auca Mahuevo in the southern region of Patagonia by a shepherd, but the find was only made public this week by local Cultural Heritage Director, Claudia Della Negra, Argentina’s Telam news outlet reported. There Are Huge Tunnels in South America Dug By Extinct Giants Sloths. Deep inside Brazil, there are tunnels large enough for a person to walk through.
DNA clues to why woolly mammoth died out. Image copyright SPL The last woolly mammoths to walk the Earth were so wracked with genetic disease that they lost their sense of smell, shunned company, and had a strange shiny coat.
That's the verdict of scientists who have analysed ancient DNA of the extinct animals for mutations. The studies suggest the last mammoths died out after their DNA became riddled with errors. The knowledge could inform conservation efforts for living animals. There are fewer than 100 Asiatic cheetahs left in the wild, while the remaining mountain gorilla population is estimated at about 300. Cave Paintings Help Unravel the Mystery of the ‘Higgs Bison' For 15 years, scientists have puzzled over the results of genetic tests from European bison remains that date back to the last ice age.
The DNA found in the bones and teeth of many animals contain sections of genome from an unknown bovine species, reports Jessica Boddy at Science. Researchers dubbed the creature “Higgs Bison,” a play on the Higgs Boson, the “God Particle” that eluded detection by physicists for almost 50 years. But now, cave art and further DNA testing have finally unraveled the origins of Higgs Bison, which turns out to be a previously undescribed hybrid animal. The research appears in the journal Nature Communications. The mystery first emerged when Alan Cooper, researcher at the Australian Centre for Ancient DNA at the University of Adelaide, and his team began sequencing DNA from ancient European bison to study past impacts of climate change, writes Eva Botkin-Kowacki at The Christian Science Monitor.
Earth - What was Earth's first predator and when did it live? Around the world right now, thousands of animals are about to die.
The game is up for untold numbers of deep-sea fish, mountain-dwelling hares, subterranean earthworms and high-flying songbirds. They are all seconds away from becoming dinner for predators like lions, eagles and sharks. But when did this carnage begin? Have predators stalked the Earth since the origin of life itself? Or was our primordial planet once a Garden of Eden where species lived in peaceful co-existence? Sabercats and Other Carnivores Kept the Ice Age World Green. The huge herbivores of the Ice Age were ecosystem engineers.
Wherever they went, mastodons, sloths, bison, and their ilk changed the landscape by eating, defecating, trampling, and otherwise going about their plant-mashing business. Earth - The most powerful marine reptile ever. Earth - A pair of cave lion cubs has been found mummified. After thousands of years trapped beneath the ice, their young faces are still covered in fur.
You can even make out the whiskers on their cheeks and the tips of their sharp retractable claws. Named for the Siberian riverbank where they were found, Uyan and Dina are the most complete cave lion remains ever discovered. They could prove key to learning more about a species that became extinct over 12,000 years ago. Incredible Study Demonstrates the Strong Likelihood That Dinosaurs Were Tripping out on LSD.

Scientists who have analyzed a perfectly preserved amber fossil from a cave there say it's entirely possible. The amber fossil contains evidence of the earliest grass specimens ever discovered—about 100 million years old—and that they were topped by a fungus similar to ergot, which has long been intertwined with animals and humans. Ergot is known as a medicine and a toxin. Storms bring forth prehistoric treasures. Tom Stienstr, San Francisco Chronicle By Tom Stienstra Updated 11:37 am, Sunday, December 21, 2014.
Scientists "Resurrect" A 410 Million-Year-Old Spider With CGI. Nest of Young Dinosaurs with 'Babysitter' Discovered. A nest of baby dinosaurs with what might have been a juvenile babysitter sitting atop them has been discovered in China, researchers say. These findings help shed light on how sociable these ancient reptiles might have been, scientists added. The oldest known dino nesting sites are 190 million years old, and their existence suggests that even the earliest dinosaurs may have exhibited complex family behaviors. The new findings center on a 2-foot-wide (60 centimeters) rock slab that contains skeletons of 24 very young dinosaurs and the skull of one older dinosaur. The finding suggests that a caretaker was overseeing a group of hatchlings, the researchers said. [Image Gallery: Dinosaur Daycare] "In my opinion, this fossil is one of the most beautiful dinosaur fossils known," said lead study author Brandon Hedrick, a vertebrate paleontologist at the University of Pennsylvania in Philadelphia.
Long Before Trees Overtook the Land, Earth Was Covered by Giant Mushrooms. GSA press release - Giant Kraken Lair Discovered. Boulder, CO, USA - Long before whales, the oceans of Earth were roamed by a very different kind of air-breathing leviathan. Snaggle-toothed ichthyosaurs larger than school buses swam at the top of the Triassic Period ocean food chain, or so it seemed before Mount Holyoke College paleontologist Mark McMenamin took a look at some of their remains in Nevada. Now he thinks there was an even larger and more cunning sea monster that preyed on ichthyosaurs: a kraken of such mythological proportions it would have sent Captain Nemo running for dry land.
Dinosaur Feathers Found in Ancient Amber. These feathers got stuck in a glob of amber millions of years ago. Image credit: Science/AAAS Instead of digging through rocks and rubble to find fossils, a group of Canadian paleontologists decided to dig through museums’ amber collections instead. Their unique approach paid off when they discovered feathers and never-before-seen structures, which they think are something called dinofuzz. The Sixth Mass Extinction?
