We all have muscles that will move our ears around a little bit. The general consensus is that the ability to wiggle your ears is thanks to one gene, which has been turned off for some people, though, most of us don’t naturally know how to wiggle our ears voluntarily, even if we had the gene. Just as animals perk up their ears, humans can, too, and it is possible to learn how.
Hey, if I can do it, I bet you could too! 😉
