Dear Hum
an Body Dwellers,
Today we’ll begin studying the human body. The human body is an organism and like all organisms, everything it does it does to survive.
Living creatures have developed a lot of fascinating and creative ways to stay alive in the world. Anytime you see one of these strange adaptations, you should always ask the same question: how does this help the organism survive?
No matter how silly an animal’s adaptation may look (and there are certainly some silly looking animals out there) the purpose is to help the organims survive.
Sincerely,
Mr. Heimbuck
