Remote Ready Biology Learning Activities

Remote Ready Biology Learning Activities has 50 remote-ready activities, which work for either your classroom or remote teaching.

This web exhibit was first built in 2000 by Patricia Anne Kinser, Haverford College, under the direction of Paul Grobstein, Bryn Mawr College. The updated version of Comparative Neuroanatomy and Intelligence is now online at This old version has been archived in place, and will continue to be available for teachers and students who are using it.

The Question of Intelligence





Now that body size and brain size are out of the equation, are there any differences between all these brains?

It seems that there are still structural differences that are quite apparent in all these brains.

human brainsquirrel brain Some brains seem to have more grooves and indentations in the cortex than others.

cat brainmonkey brain Some brains seem to have larger or more noticeable structures than others.

squirrel brainrabbit brain Some brains of animals which we assume would be similar actually look quite different (for example, a squirrel, left, and a rabbit, right).

So, in other words, although we've made all the brains equal in size, there still seems to be some differences that have nothing to do with size. This leads us to a question: is intelligence and behavioral complexity more related to size of the brain or to some kind of structural difference within the brain? Why don't we look closer and find out?!

You now have a choice . . . Do you want to look closer into these brains and examine various structures? Or do you want to look at intelligence issues?

Yes, let's slice into these brains!

I want to talk about intelligence, please

Huh? Can we start over?
