What is the relationship between brain and body size??

In this table, we focused on the heads of the animals and made the pictures (both of heads and brains) proportional to each other as they are in real life. Can you look at this table and make any observations about brain and body size? Do bigger animals have bigger brains?

human brain

(You can look again at this chart to see the approximate values for brain/body lengths and weights)

So, more or less it looks like bigger animals have bigger brains and smaller animals have smaller brains . . .

What if all these animals had the same body size?

Why should I care about this kind of comparison??

Huh? Can we start over?
