Wombat Poop Cubes

Why?
“Hu speculates that because the animals climb up on rocks and logs to mark their territory, the flat-sided feces aren't as likely to roll off from these high perches.”

How?
“Softer intestinal regions squeeze slowly and mold the final corners of the cube, the team found. In other mammals, the wavelike peristalsis of the intestinal muscles are consistent in all directions. But in the wombat, the grooved tissue and the irregular contractions over many cycles shape firm, flat-sided cubes.”

So?
“Hu admits that it's "not going to replace the way we manufacture plastic." But the wombat's strategy could help engineers design better ways to shape valuable or sensitive materials, he says.”
