Brain and Body Size

What is the relationship between brain and body size?

In this table, all the animal heads are approximately in proportion to each other (and each respective brain is in relation to its owner). Can you look at this table and make any observations about brain and body size?

human brain human
baboon brain baboon
monkey brain monkey
camel brain camel
dolphin brain dolphin
kangaroo brain kangaroo
cat brain cat
raccoon brain raccoon
rabbit brain rabbit
squirrel brain squirrel
frog brain frog

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


Would you rather equalize brain size or equalize body size?
