And plenty of people have small heads and are unusually intelligent or vice-versa. That's not what he's saying. Compared with monkeys or a...

yes it is, parts of the golgi apparatus "break off" and either send enzymes to the plasma membrane where they are then placed outside the cell or sent to another part of the body. The golgi apparatus isn't fixed to another organelle, it uses the same transport system for everything and the endoplasm...
