What is the purpose of floppy ears?
Over years and millennia, humans selectively bred dogs to have more desirable traits (like being friendlier or tamer). Floppy ears, while adorable, were simply a byproduct of this domestication and breeding for tameness. Scientists have even given this phenomenon a name: domestication syndrome.
Where do floppy ears come from?
The adrenal gland is formed by “neural crest cells.” These cells also move to the different parts of an animal where these changes between wild and floppy-eared domestic animals are most obvious. The researchers theorize that if the neural crest cells don’t reach the ears, then they become somewhat deformed, or floppy.
Do dogs naturally have floppy ears?
But the ears of many dogs are distinctly floppy. “The incapacity to erect the ears,” Darwin concluded, “is certainly in some manner the result of domestication.”
Why do domestic animals have floppy ears?
Because the development of neural crest cells is degraded in domesticated animals, these cells don’t have the chance to spread uniformly throughout the body. Cartilage, too, is derived from neural crest cells, which is why domesticated animals tend to have floppy ears.
Is there any cats with floppy ears?
Scottish fold cats are known for their trademark folded ears that make for an adorable look. They have round faces and big round eyes, and their folded ears make them appear even rounder. In fact, they’re often compared to teddy bears or owls.

Are floppy ears better for hearing?
“Pricked-up ears may be slightly more efficient than other ear shapes, since sound waves are able to go right in. Floppy ears present a problem. The sound waves have to pass through a big, heavy flap before reaching the eardrum.
What frequency will hurt a dogs ears?
20,000 Hz
Why can dogs hear things we can t?
Dogs have better hearing than humans both because they can hear these high-frequency sounds, and they can hear sounds from farther away. This is because of the way their ears are designed. Their ears are made to cup and move sound in, similar to the way humans can put a hand up to their ear to hear better.
Does Ear cropping affect hearing?
The outer ear is shaped to capture sound waves and funnel them into the ear canal and towards the eardrum. It’s not yet known whether surgical changes (such as ear cropping) affects hearing but it’s possible.
