Zoology Class

My chordate zoology class really makes me think, and i love it. It involves identifying a bunch of bones in the skeleton, which is a bit of an annoyance. However, comparing bones with different kinds of animals to each is quite remarkable. It shows undeniable facts that evolution is true. Humans, bats, frogs, salamander, and many others all have 5 fingers and homologous bones, humerus, radius, and ulna. There's so many species out there that it is crazy to think we all have a common ancestor.
