I can wiggle my ears but they aren’t strong enough to propel me through the water.

This reminds me of the story of the woman who lost the swimming competition in the breast stroke. She complained to the judges that the other competitors had been cheating by using their arms.

Mammal ears (thus human ones) evolved from the extra bones in the jaw typical of early amniotes (a group which also gave rise to reptiles and birds). The dentary (the part of the jaw containing the teeth) remained in the jaw (in the case of mammals, becoming the entire jaw) and the other bones moved into the ear. They’re still in the jaw in reptiles, which is why they cannot hear very well unless their jaw is in direct contact with the ground.
Dunno why they’re making such a big deal about human ears. The same could be said of nearly any terrestrial vertebrate species. Why not write the headline as “donkey ears evolved from gills” or “reticulated python ears evolved from gills”?
Perhaps it is because we are an egocentric species. Then again, it may be because donkeys and pythons are less likely to read the article anyways. ![]()
