This is my best attempt to follow wiki conventions, I'm new. Read all my entries before you edit. Understanding of this topic by most is not impressive. We all need to keep reading so we can educate those don't have the time or resources to teach themselves. This topic is important to all vertebrates. Please consider.
This site has huge potential. I wish it was around when I was 10 years old. User:Danm 23:29, 3 December 2009
