People used to think the Ice Age people lived in [originaltext]M: Hey, Jane. Wha

M: Hey, Jane. What’s so interesting?
W: Oh, hi, Tom. I’m reading this fascinating article on the societies of the Ice Age.
M: The Ice Age? There weren’t any societies then, just the bunch of cave people.
W: That’s what people used to think. But a new exhibition at the American Museum of National History shows that Ice Age people were surprisingly advanced.
M: Oh, really? In what ways?
W: Well, Ice Age people were the inventors of languages, art and music as we know it. And they didn’t live in caves. They built their own shelves.
M: What did they use to build them? The cold weather would have killed almost all of the trees, so they couldn’t have used wood.
W: In some warmer climates, they did build houses of wood. In other places, they used animal bones and skins or lived in natural stone shelters.
M: How did they stay warm? Animal skin walls don’t sound very sturdy.
W: Well, it says here, that in the early Ice Age, they often faced their homes towards the south to take advantage of the sun, a primitive sort of solar heating.
M: Hey, that’s pretty smart!
W: Then people in the late Ice Age even insulated their homes by putting heated cobblestones on the floor.
M: I guess I spoke too soon. Can I read that magazine article after you’ve done? I think I’m going to try to impress my anthropology teacher with my amazing knowledge of Ice Age civilization.
W: Ha... What a show-off!
