Laetoli Footprints and Lucy the Australopithecus (Classroom Series)

We know our early ancestors, like Lucy, were walking upright because we found her footprints in Tanzania.

Wait a minute. Weren't those footprints, like, a thousand miles away from where Lucy was found? Yeah, give or take. Well, how big were her foot fossils?

Well, they didn't actually find Lucy's hands or feet. Well, so how big were the actual Tanzania footprints?

About ten inches long. That's how big my feet are, and I only wear a nine and a half. So wait a minute.

So they never found her feet. But Lucy, a three and a half foot tall person, made ten inch long footprints a thousand miles away?
