A dog's gait, according to the American Kennel Club, is "the pattern of footsteps at various rates of speed, each distinguished by a particular rhythm and footfall." When dogs trot, for example, the right front leg and the ...
A new study shows that the roots used by three close species of microscopic Daphnia crustaceans to settle across the territory of Northern Eurasia differed greatly. The findings shed light on how continental freshwater fauna ...
Around 4 billion years ago there lived a microbe called LUCA: the Last Universal Common Ancestor. There is evidence that it could have lived a somewhat 'alien' lifestyle, hidden away deep underground in iron-sulfur rich hydrothermal ...
Gene trees, much like family trees, trace the lineage of a particular gene from its deep ancestral roots to its still-growing branches. By comparing gene trees to species trees, which map the evolutionary history of species, ...
As a principal investigator in the NASA Ames Exobiology Branch, Andrew Pohorille is searching for the origin of life on Earth, yet you won't find him out in the field collecting samples or in a laboratory conducting experiments ...
It's as long as a snake, is spotted like a leopard, has two small arms with gills sticking out of its body and it lives in the swamps of Florida's panhandle. What is it?
Corals and the microbes they host evolved together, new research by Oregon State University shows.
In the dramatically changing conditions of ancient Earth, organisms had to evolve new strategies to keep up. From the mid-Oligocene, roughly 30 million years ago, to the mid-to-late Miocene, about 5 million years ago, carbon ...
The evolution of barn swallows, a bird ubiquitous to bridges and sheds around the world, might be even more closely tied to humans than previously thought, according to new study from the University of Colorado Boulder.
Aequatus—a new bioinformatics tool developed at Earlham Institute (EI) - is helping to give an in-depth view of syntenic information between different species, providing a system to better identify important, positively-selected, ...
