Human architecture is based on the usefulness of the senses.
Our ears are designed in order for us to receive signals from the world where our eyes cannot see.
Because we can keep our ears clean using our hands, our 'ear flaps' don't need to be as large as other animals' ear flaps. Also, our other senses offer us more information, so our ear flaps don't require more area to capture sounds and direct them into our hearing sense mechanisms.

Do mice have ears?
Humans, dogs, cats, and other furry animals are mammals and obviously have ears.
Why do animals move their ears when they hear a sound?
It is smaller animals that can move their ears in different directions. Such animals need to hear the sounds made by smaller predators. Larger animals do not need that skill and do not have it. Instead, humans depend more on sight. Humans frequently stay in herds with at least one looking behind for a predator. Other large animals stay in herds. They do not move their ears. Instead, they watch. The noise large predators make does not carry far. So, they do not hear a lion walking. They can see him coming.

Do pukeko have ears?

Do koalas hear?

Do all animal use their ears to hear?
Not all animals that hear have external ears like many mammals do, but many can sense the vibrations that we perceive as sound through other sensory organs, which you might call "ears".
How do true seals hear?
True seals have ears, just not external ears. Their ears are simple holes on the sides of their heads, but they have the same general internal ear structures as any other mammal. Sound carries very well in water, so true seals can hear perfectly well when submerged. Note that other marine mammals - whales, dolphins, manatees and such - also lack external ears. In air, they can still hear, but perhaps not as well as some other mammals.
How can humans hear?
humans hear from there ears.
