Cause they all fly
They also both eat insects, and have fingers.
Birds and bats are homoplasious because they are similar, but not derived from a common ancestor. An example of homologous structures is a man's arm and a cow's foreleg. They are anatomically similar but have different functions.
Convergent evolution
convergent evolution bro.
The term that describes the process resulting in birds and bats having similar wings is "convergent evolution." This occurs when different species independently evolve similar traits or adaptations in response to comparable environmental challenges or ecological niches. Despite their different evolutionary backgrounds, both birds and bats have developed wings as a means of flight, demonstrating how similar pressures can lead to analogous structures.
Bats do, birds do not
Birds and bats
Bats are mammals, birds are not. Birds lay eggs, bats do not.
Both bats and birds are warm-blooded vertebrates.
Bats have fur but birds do not. Bats are mammals that give birth to live young, whereas birds give birth by way of the laying of eggs.
Bats are not birds. Bats are flying mammals. Some birds have a rudimentary echolocation capacity. These birds are the oilbirds of South America, and the cave swiftlets of Asia.
A bat bears it's young alive, does not have feathers and does not have the high metabolic rate of a bird.
we are similar to a bird because birds got leags and birds has a mouth. Plants are a kind of flora (plant life). Birds and people are both fauna (animal life). Therefore people are similar to birds.
