32.2 Evolution of hominids
| | |
- Humans (Homo sapiens) are in the order primates and the family Hominidae (extinct and modern humans).
- About 5 MYA, australopithecines (the first hominids) evolved in Africa. The australopithecines had a relatively small brain, but they could walk upright.
| - What are the characteristics distinguishing hominids from other primates?
Answer - What is the hypothesized early environment of hominids and how did bipedalism help?
Answer - ___________________ occurs when different structures evolve at different times and rates.

32.3 Evolution of humans
| | |
- About 2 MYA, early Homo types evolved which had a larger brain than the australopithecines and were able to make primitive stone tools.
- Forms of Homo erectus are found in both Africa and Asia. H. erectus had a knowledge of fire and made more advanced tools.
- The out-of-Africa hypothesis says that modern humans evolved in Africa and after migrating to Europe and Asia (about 100,000 years BP2), they replaced the archaic Homo species, including the Neanderthals.
- Cro-Magnon is the name given to modern humans who made sophisticated tools and definitely had culture.
- Today humans have various ethnic backgrounds. Even so, genetic evidence suggests humans share a fairly recent common ancestor and significant differences are due to adaptations to local environmental conditions.
| - Explain the multiregional continuity hypothesis.
Answer - What is the hypothesis that proposes evolution of Homo sapiens from H. erectus in Africa and then a migration of humans to other areas where they developed different characteristics?
