Still Waters Posted March 31, 2020 #1 Share Posted March 31, 2020 Taking the evolutionary plunge into water and abandoning land for good, as some crocodilian ancestors did nearly 200 million years ago, is often framed as choosing freedom: from gravity, from territorial boundaries, from dietary constraints. Water might inflict more pressure in the pounds-per-square-inch sense, the thinking went, but it also probably relieved some—especially the sort that kept crocs from going up a size or 10. If they wanted to enjoy the considerable spoils of considerable size, water seemed the easy way. A recent study from the University of Nebraska-Lincoln's Will Gearty, who compiled a database of 264 species stretching back to the Triassic Period, says that freedom was actually compulsion in disguise. https://phys.org/news/2020-03-pressure-ancient-aquatic-crocs-evolved.html 2 3 Link to comment Share on other sites More sharing options...
