A new statistical analysis of dinosaur diversity shows they were not in decline at the time of their extinction by an asteroid hit 66 million…
Birds travel across habitats patches to breed, unlike their forest counterparts. Picture the Amazon. You’re thinking lush rainforests teeming with animals, right? It turns out,…
Paleontologists have made a surprising discovery while searching through 100-year-old fossil collections from the UK – a new mystery species of pterosaur, unlike anything seen…
A large international consortium led by scientists at Uppsala University and the Broad Institute of MIT and Harvard has sequenced the genome of 130 mammals…
An international team of biologists, led by Monash University, has discovered a new species of extinct monk seal from the Southern Hemisphere – describing it…
New epidemic diseases have an evolutionary advantage if they are of “intermediate” severity, research shows. Scientists tested the theory that pathogens (disease-causing organisms) that inflict…
The Zoonomia Project has released this vast dataset to advance both biomedical research and biodiversity conservation. An international team of researchers with an effort called…
Fossil cranium suggests environmental conditions drove rapid changes. Males of the extinct human species Paranthropus robustus were thought to be substantially larger than females —…
Similar to bacteria evolving resistance to antibiotics, viruses can evolve resistance to vaccines, and the evolution of SARS-CoV-2 could undermine the effectiveness of vaccines that…
First analysis combining genetic and physical differences of populations of gentoo penguins indicates they should be treated as four separate species. Gentoo penguins should be…
The era of COVID-19 and the need to constantly wash one’s hands and sanitize things have brought microbes to new levels of scrutiny, particularly for…
The first fossils of a duckbilled dinosaur have been discovered in Africa, suggesting dinosaurs crossed hundreds of kilometers of open water to get there. The…
Argonne computational resources supported the largest comprehensive analysis of COVID-19 genome sequences in the U.S. and helped corroborate growing evidence of a protein mutation. Before…
Published in the prestigious Society of Vertebrate Paleontology Memoir Series, these landmark findings of over 350 fossils, will become a reference point for the origin…
Fossils of bizarre, armored amphibians known as albanerpetontids provide the oldest evidence of a slingshot-style tongue, a new Science study shows. Despite having lizardlike claws,…
Most mammals — including humans and other primates — reach sexual maturity early or late depending on lots of different factors, such as how much…
The Arthropods have been among the most successful animals on Earth since the Cambrian Period, about 520 million years ago. They are the most familiar…
