About 66 million years ago, at the end of the Cretaceous period, a 10-km-wide asteroid crashed into Earth near the site of the town of Chicxulub in what...
A new genus and species of monofenestratan pterosaur being named Propterodacylus frankerlae documents the transition from the more ancient rhamphorhynchoid...
Our given name is a social tag associated with us early in life. Prior research has shown that individuals’ facial appearance can be indicative of their...
Parapontoporia, an extinct genus of long-snouted dolphins that lived off the Pacific coast of North America from the Late Miocene epoch until the Pliocene,...
The evolution of the first animals on land, 500 million years ago, has been revealed. The ancestors of millipedes, called euthycarcinoids, evolved in warm...
Eastern Africa preserves the most complete record of human evolution anywhere in the world but scientists have little knowledge of how long-term biogeographic...
Paleontologists have described a new species of snake from the Early Oligocene of Wyoming based on four nearly complete and articulated specimens found...
A team of scientists in China has assembled a telomere-to-telomere reference genome for ginseng (Panax ginseng), a representative of Chinese traditional...
The last universal common ancestor (LUCA) is the hypothesized common ancestor from which all modern cellular life, from single celled organisms like bacteria...
Within the uncertainties of involved astronomical and biological parameters, the Drake equation typically predicts that there should be many exoplanets...
Paleobotanists have described nine new species of the grape family Vitaceae on the basis of 60- to 19-million-year-old fossil seeds discovered in four...
Fossil and molecular evidence suggests that complex multicellular organisms originated and proliferated during the Neoproterozoic Era (1,000-541 million...
A new genus and species of unenlagiine dinosaur has been identified by paleontologists in Argentina. Named Diuqin lechiguanae, it fills a substantial gap...
New World porcupines originated in South America and dispersed into North America between 4 and 3 million years ago. Prehensile-tailed porcupines today...
A new genus and species of furileusaurian abelisaurid that lived during the Cretaceous period has been identified from fossilized skeletal remains found...
The evolution of feathers is associated with novel skin ultrastructures, but the fossil record of these changes is poor and thus the critical transition...
Paleontologists from the University of Liège and elsewhere have investigated the evolutionary patterns behind the development of saber teeth in two groups...
Euchelicerata is a large group of arthropods comprising horseshoe crabs, scorpions, spiders, mites and ticks, as well as the extinct sea scorpions and...
