Bats are vital for maintaining balance in the ecosystems they are a part of: Bats keep insect populations in check, pollinate flowers, and disperse seeds. Bats are also an incredibly diverse group of species that come in all shapes and sizes! Did you know, that if you randomly picked a mammal, you would have a one in five chance of picking a bat? Today we have Dr. Alexa Sadier with us to talk about what studying bats can teach us about evolution.
