The fastest animals are neither large elephants nor tiny ants, but intermediately sized, like cheetahs (Acinonyx jubatus). Why does running speed break...
A new camera system and associated software package allows scientists to produce videos that accurately replicate the colors that different animals see...
The Whale-SETI team, which includes researchers from the SETI Institute, University of California Davis and the Alaska Whale Foundation, has been studying...
Namibia is rich in hunter-gatherer rock art from the Later Stone Age. This is a tradition of which well-executed engravings of animal tracks in large numbers...
Mass extinctions during the past 500 million years rapidly removed branches from the tree of life and required millions of years for evolution to generate...

Bicellum brasieri, a freshwater protist that lived nearly one billion years ago, had two distinct cell types and could be the earliest multicellular animal...
In a paper published in the journal iScience, a team of marine biologists from Japan, the United States and France reports the discovery of circling behavior...
Paleontologists have described the first three-dimensional preservation of soft tissue in Namacalathus hermanastes, a skeletal metazoan (multicellular...
An international team of biologists has discovered that a tiny parasite of salmon called Henneguya salminicola has no mitochondrial genome and thus has...
Complex animals evolved from single-celled ancestors, before diversifying into 30-40 distinct anatomical designs. When and how this major evolutionary...
A 10-minute college-based animal visitation program providing hands-on petting of cats and dogs provides momentary stress relief, according to a study...
