We're in this business for the unanswered questions

This episode of Crash Course Zoology has something I love. It shows scientists not being afraid of evolution mysteries or being wrong about anything. That's right, creationists. This seems to be their main line of attack. They will get nothing from me when I point out that our knowledge is incomplete. Yes, we do know. This is why scientists were created.It also has spiders.Next episode will be about species concepts. It will be so nice to finally get that one explained.
