Amphioxus adults were fed a diet of live unicellular algae and allowed to spawn spontaneously, en masse, in closed aquaria containing 60–150 animals. The larvae from mass spawning events were ...

It turns out lampreys, long thought to have taken a different evolutionary road than almost all other backboned animals, may not be so different after all, especially in terms of the genetics that ...

Vertebrate skeletal tissues exhibit remarkable diversity in both their mechanical properties and evolutionary adaptations. These tissues are finely tuned composite materials where a combination of ...

Scientists at the University of Kansas have come up with new ways to capture stunning images of vertebrate skeletons. Until now, it was common for researchers to "stain" bones with dyes and dissolve ...

In vertebrates, the skeleton of different regions of the body arises from different precursor cells. Researchers at the University of Basel have now discovered that these skeletal cells do not just ...

July 31 (UPI) --New X-ray images of ancient fish fossils have helped scientists solve a 160-year-old mastery about the origins of the vertebrate skeleton. Heterostracans are a group of fossil fishes ...

Scientists at the University of Manchester and the University of Bristol have used powerful X-rays to peer inside the skeletons of some of our oldest vertebrate relatives, solving a 160-year-old ...

An amphioxus in the Daniel Medeiros lab is seen with most of its body burrowed into sand and its mouth exposed, as it waits for food to drift by. Photo by David Jandzik. The findings suggest that the ...

The Skeleton System provides the hard structure or framework to the human body which support and protects the body. It is composed of connective tissues like bones, cartilage, tendons and ligaments.
