In the table below all of the animals now have the same body sizes. Compare the brains of these animals. Was your hypothesis correct? Is there any difference in brain size now?

	body size=1m
	body size=1m
	body size=1m
	body size=1m
	body size=1m
	body size=1m
	body size=1m
	body size=1m
	body size=1m
	body size=1m
	body size=1m

So, what did you notice? Are the brains all the same size when body sizes are the same? Or are some brains larger than others?

I'm not sure... can we talk about this some more?

Brains do vary in size and, even for animals of the same size, some have smaller brains and some have larger brains. So it looks like, at least in that sense, animals that behave differently have different brains. Even more, you may have noticed differences between the brains in addition to differences in size. To more clearly see that, it might help if we made all the brains the SAME size and then we can focus on other differences . . .

What if all these animals had the same brain size?

Huh? Can we start over?
