You know they still cant put evolution and how our brain works together yet. Its an anomaly they we are smart since the top tier of the ocean, Sharks, have very small brains and intelligence does not evolve to the top of the food chain.

"...since the top tier of the ocean, Sharks, have very small brains and intelligence does not evolve to the top of the food chain..."

Dolphins have big, smart mammal brains, and have been known to attack and fend off sharks. ORCAs (killer whales) also have big, smart mammal brains, and not a lot of sharks get to eat them.

Sharks are certainly well adapted, efficient killing and eating machines, no question there, but as for being at the top of the food chain without challenge from "bigger brained" animals, there is considerable room for argument.
