Brett Smith for redOrbit.com - Your Universe Online One of the earliest primates, Purgatorius, was a small, rodent-like mammal thought to have lived along forest floors after the extinction of the dinosaurs. However, a new study – based on the creatures’ ankle bones from researchers at Yale University – has found that these "proto-primates" actually lived in trees. Researchers had suspected that Purgatorius lived in trees at one point, but thought they started out on the ground....
It seems like most divorces happen around the seven-year mark, "the seven-year itch," as it's been termed. But how much science is there behind this trend? Biological anthropologist Helen Fisher digs into the phenomenon and finds some surprising correlations.
A collaborative network designed to host, manage, analyze and share phenotypic and genotypic studies of plants and animals, Project Unity, in beta, is provided free of charge to the academic community.
Just as getting drunk can impact a person’s ability (and willingness) to sing, consuming too much alcohol can have a similar effect on some types of birds, researchers from the Oregon Health and Science University (OHSU) have discovered in a new study.
Robert Meredith, an assistant professor of biology and molecular biology at Montclair State University, is a lead author of “Evidence for Tooth Loss and the Acquisition of a Horny Beak in the
The secrets of how modern birds evolved and emerged following the mass extinction of the dinosaurs some 66 million years ago have long been hidden in their genes.
Birds that are related, such as Darwin’s finches, but that vary in beak size and behavior specially evolved to their habitat are examples of a process called speciation.
After an exhaustive two-year period of research, a large international team of scientists has finally unveiled its comprehensive evolutionary tree of insects on Earth in the journal Science.
Researchers have located fossil evidence of an amphibious ichthyosaur, a discovery that for the first time links the dolphin-like ichthyosaur to its terrestrial ancestors and is reported in the November 5 advance online edition of the journal Nature.
A new study from Penn State and Brown University reveals that politics can have unintentional evolutionary consequences. These consequences can cause hastily issued policies that cascade into global, multigenerational problems.
Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...
- In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
