A matter of great debate and ardent discussion in the field of evolutionary biology today is the transition of complex life from a watery environment to land. So far, there have been numerous speculations put forward in attempt to explain how tetrapods (four-legged land animals) first evolved and washed ashore to start life fresh as […]
Researchers who had performed the first high detail 3-D reconstruction of early tetrapod (four-legged animals) backbones claim the first land based animals moved by dragging themselves around the ground much in the same way modern day seals behave. The scientists used the European Synchrotron Radiation Facility (ESRF) in Grenoble to bombard 360-million year old fossils with high […]
Researchers studying a primitive fish exhibiting an eel-like body, and which can breath above water, claim that the creature’s ancestors might actually be the true innovators of walking. By using an extensive video analysis, the researchers observed how the African lungfish, when put out of the water, uses its pelvic muscles to not only lift itself […]
A study into muscle development conducted on several fish has given valuable insight regarding the genetic leap that moved the scene from the aquatic parts onto the land. It was this particular leap that gave birth to tetrapods, animals that walk on four legs and are our very distant ancestors. Peter Currie, of the Australian […]
