Alex Pyron’s expertise is in family trees. Who is related to whom, who begat whom, how did they get where they are now. But not for humans: reptiles.
Floral morphologies may be less reliable than other traits in determining the relationships of papilionoid species and genera
Whether we look back to the origin of life on this planet some four billion years ago or we examine a more recent and larger life form, in dinosaurs, it is important to recognize the ecosystems that provided a home for them have, like the life that inhabited them, evolved.
Experts from the Centre for Advanced Studies of Blanes and the University of Barcelona (UB) collected and studied different crustacean specimens during recent expeditions to Madagascar, New Caledonia, Vanuatu, the Philippines and French Polynesia.
According to a new study in the journal Trends in Ecology and Evolution, determining if certain extinct animals had sexually selective traits is possible, despite the fact that we cannot observe their behavior.
A new study from researchers at the University of Auckland, Griffin University and the University of Oxford has debunked claims that most species will go extinct before they can be discovered.
When Charles Darwin first sketched how species evolved by natural selection, he drew what looked like a tree.
A research lab has identified the genetic markers for an endangered species of elephant, showing the animals have very low genetic variability.
A vast undertaking has been launched to catalog the life that inhabits our world’s oceans. For the first time, a comprehensive register of marine species has been compiled. This effort was part of a massive collaboration among hundreds of experts around the globe.
Evolution, often perceived as a series of random changes, might in fact be driven by a simple and repeated genetic solution to an environmental pressure that a broad range of species happen to share, according to new research.
Paleozoology, also spelled Palaeozoology, is a branch of many other sciences including zoology and paleontology that focuses on recovering cellular matter from animal remains that are large enough to be seen without the help of a microscope, known as macrofossils. This study is primarily used in the context of archeology and geology and aids in recreating ancient ecosystems and prehistoric environments. Paleozoologists study the tissues of many types of animals including sharks, echinoderms,...
The Three-Spined Stickleback, Gasterosteus aculeatus, is a fish native to much of northern Europe, northern Asia and North America. It has been introduced into parts of southern and central Europe. Three subspecies that are currently recognized by the IUCN are Gasterosteus aculeatus aculeatus, which is found in most of the species range, and is the subspecies most strictly termed the Three-Spined Stickleback; its common name in England is the Tiddler, although "tittlebat" is also sometimes...
