What is the relationship between brain and body size??
Clearly different animals have differently sized brains. How important is brain size for behavior? Some people have thought that brain size is strongly related to intelligence. But, as you may have noticed, it also looks a bit like brain size may simply be bigger in bigger animals and smaller in smaller animals-- regardless of "intelligence".
On the next couple of pages will be a series of tables designed to help us visualize brain size in relation to body sizes and develop questions from that. The table below shows, on the left, brains whose apparent size is appropriate for the pictures on the right. Click on the pictures of the animals to read specific information about the species. Since the pictures on the right don't accurately show relative sizes of the animals, we can't conclude from this much about whether bigger animals have bigger brains.

The actual sizes of the animals and brains are given in this this chart. But it may be easier to do some comparisons by changing the size of the pictures . . .
How do the brain sizes compare when the animal pictures are correctly in proportion?
Why should I care about this kind of comparison??
Huh? Can we start over?
