SO....today in AP Bio....we watched a video about Charles Darwin...
Darwin believed we came from....
FISH....because all human embryos have gill like features....so...my conclusion is...

Kisame is a shark....
Sharks are fish...
thus...Kisame is the missing link. :D
SO
Let us take a moment to think about our missing link...KISAME

*does not believe in Darwin's theory* :P
