What are some animals that are similar to humans in unexpected ways?
Here's some examples I can think of. (Note that I consider chimpanzees and other species closely related to humans to be cheating, since there's a good chance they evolved that trait as part of a common ancestor instead of independently.)
- The indri is a type of large lemur that is the only mammal other than humans that can hear rhythm.
- The only other mammals other than humans to undergo menopause are certain cetaceans like orcas, belugas and narwhals.
- Beavers are the only other mammal that can actively shape their environment.
- While homosexuality is common in the animal kingdom, sheep are the only non-human animal capable of being EXCLUSIVELY attracted to the same sex, with 10 percent of rams preferring other rams.
- Ground hornbill evolution somewhat parallels humans, in that they started out as arboreal frugivores before transitioning to grassland predators.
- Many ants have domesticated livestock like aphids and caterpillars for their honeydew.
- There's a species of damselfish that farms algae, and has domesticated a type of shrimp to help fertilize it with their droppings the same way many farmers in Asia use ducks.
