Chapter 21 Lecture Enrichment Ideas
Discuss why it is incorrect to say that humans descended from apes, since humans and apes are both descended from a common ancestor that was not a modern ape or human. Point out that if you go back far enough, we have a common ancestor with a dog, a lizard, a frog, a fish, an earthworm, a plant, or a bacterium.
Discuss how the development of language and culture makes the human so different from our closest relatives, the chimpanzees.
Query students for what makes humans unique. Tool use? Language? Hand grip? The ability to know what we know (compartmentalization)?
