Rabbit ears evolved primarily for hearing and temperature regulation. Over time, natural selection favored rabbits with large, upright ears because they provided key survival advantages:
Enhanced Hearing – Rabbits are prey animals, so having large, sensitive ears helps them detect predators from far away. Their ears can rotate independently, allowing them to pick up sounds from different directions without moving their bodies.
Temperature Control – Rabbits don't sweat like humans. Instead, they regulate body heat through their ears. The large surface area of their ears helps them release excess heat, especially in hot environments.
Different rabbit species have different ear sizes based on their habitats. For example, jackrabbits, which live in hot deserts, have extremely large ears to help cool down, while cottontail rabbits, found in cooler forests, have smaller ears since they don't need as much heat loss.
Over millions of years, these adaptations have helped rabbits survive in diverse environments.
The plural form for rabbit ears is (one) rabbit's ears; or (two) rabbits' ears.
True
It's not true that rabbits with long ears have a longer lifespan than rabbits with short ears. Ear length has no bearing on a rabbit's lifespan.
It depends on its species and size. Tiny rabbits have tiny ears.
There are many rabbits with ears sticking up. My Netherland dwarf rabbit, which is the smallest rabbit, has upright ears. Also dutch rabbits and rex rabbits do, to name some. Hope this is of some help :)
All rabbits have long ears...
of course silly! :)
Their big ears!
Their ears have gotten longer to hear better.
Genetics.
No. There are breeds who have floppy ears.
yes.
