Creatures with tiny brain size often don't get the credit they deserve for higher intelligence. Biologist Rafael Rodriguez says a case in point are spiders, who can make mental maps of their webs. This memorizing ability is similar to how humans retrace their steps when trying to find a misplaced item. Spiders also show an ability to understand the concept of numbers.

On today’s show, Rodriguez discusses the limits of a very small brain with host Tom Luljak.
