Interactive video lesson plan for: Why Do We Have Such Crooked Teeth?

Activity overview:

A lot of humans need or want braces to fix their crooked teeth, but why do you never see a dog walking down the street with headgear? Our ancient ancestors and mac and cheese may be to blame!

*Correction: Even though hyraxes look similar to rodents, they're actually in the order Hyracoidea, not Rodentia! They're more closely related to elephants and manatees than to mice and guinea pigs.*
