The first animal to crawl onto land from the ocean probably looked a bit like today's salamander, and researchers have wondered how it was able to switch from swimming to walking.

By Lee Bowman. The ability to run long distances across the African savannah gave human ancestors an evolutionary advantage over other primates that walked upright, but could not run the mile or 20, researchers argue in a new study.

Why did humans evolve to walk upright? Perhaps because it's just plain easier. Make that "energetically less costly," in science-speak, and you have the conclusion of researchers who are proposing a likely reason for our modern gait.

Fossilized dinosaurs often have wide-open mouths, heads thrown back and tails that curve toward the head. Paleontologists have long assumed the dinosaurs died in water and the currents drifted the bones into that position, or that rigor mortis or drying muscles, tendons and ligaments contorted the limbs.  &quot;I&#39;m reading this in the literature and thinking, &#39;This doesn&#39;t make any sense to me as a veterinarian,&#39;&quot; said Cynthia Marshall Faux, a veterinarian-turned-paleontologist at the Museum of the Rockies. ...
