I’m familiar with Chiroptera. What’s the other order?
I assume you’re talking about bats. The two kinds are the ordinary small insectivorous bats we see everywhereas well as the vampires, all of those have carnivore teeth, and the larger fruit bats. If you want to believe bats evolved, you have to believe they evolved twice, the two groups aren’t related. In real life, however, there is no fossil evidence of anything you’d call ancestral to any sort of bat.
