Scientists are ready to explore the natural world: Patricia Yang, researcher at Georgia Tech, and her team have inflated balloons into the bowels of wombats killed on the roads – shipped from Tasmania, hoping to understand why the excrement marsupials are cubes. "The first thing that has led to this," said Yang, according to the BBC, "is that I've never seen anything so strange in biology."
When they wander around the world, the plump herbivores are cute but glitzy. They dissuade other wombats from invading them by leaving their poop in prominent places. The experts assume that when the poop comes in cubes, it is less likely to escape. TMI Alert: While the wombats digestive tract tubes are not square, Yang's team found that the elasticity of their intestines varied to allow the cubes to come out at the end.
