Scientists from the Florida Museum of Natural History and elsewhere have sequenced 391 genes from nearly 2,300 butterfly species, sampled from 90 countries...
After the extinction of non-avian dinosaurs at the end of the Cretaceous period, many mammals underwent a rapid increase in size. Several hypotheses for...
The long-necked dinosaurs, sauropods, are famous for their extreme body sizes, evolving body masses several times greater than the next-heaviest terrestrial...
Humans have extensively shaped animals and plants through domestication. Although wine and table grapes have been important culturally for thousands of...
Different genetic traits can be beneficial (for example, fending off disease) or harmful (making humans more susceptible to illness), depending on the...
Humans, whales, elephants, and naked mole-rats all share a somewhat rare trait for mammals: their bodies are covered with little to no hair. The common...
Cratonavis zhui, a new species of pygostylian bird from the Early Cretaceous Jehol Biota of China, had a unique combination of a dinosaurian skull with...
Most birds today can lift the upper beak independently of the brain case, enabled by a series of mobile joints and bending zones in the skull. The computed...
Octopuses and their cephalopod relatives are exceptionally intelligent invertebrates with a highly complex nervous system that evolved independently from...
Scientists from the Institute for Fundamental Biomedical Research at the Biomedical Sciences Research Center ‘Alexander Fleming’ and the Smurfit Institute...
The Devonian period, which occurred 419 to 358 million years ago, prior to the evolution of life on land, is known for a series of catastrophic mass extinction...
Paleontologists from Curtin University and elsewhere have studied a three-dimensionally mineralized heart (the oldest ever found), stomach, intestine and...
Scientists from the United Kingdom and Spain have discovered that tetrapods had more complex connections between their skull bones than fish and, rather...
The evolution of land plants took place about 430 million years ago (Silurian period), when North America and Europe were conjoined in a landmass called...
The sea cows originated in the Tethys Sea, between southern Europe and northern Africa, during the latest part of the Paleocene epoch, according to a new...
