primatology ): previous research shows chimpanzee males form stronger alliances W r i t i n g
The following scenarios describe observed phenomena. Independently, pick one of the scenarios and then answer the questions that follow.
- SCENARIO A (Human Biology): Previous research shows that some human populations living at extremely high altitudes have larger lungs. Research also shows that at high elevations the oxygen concentration in the air is lower, and people in these areas are at risk of not getting enough oxygen. Generate a hypothesis about why people in high altitudes have larger lungs.
- SCENARIO B (Forensic Anthropology): Previous research shows that, in humans, the pelvic opening tends to be wider in females than it is in males. Generate a hypothesis about what causes this pattern in pelvic openings.
- SCENARIO C (Primatology): Previous research shows chimpanzee males form stronger alliances with one another than do chimpanzee females. Research also shows that adult chimpanzee females often split up and go to different areas to feed during the day while adult male chimpanzees spend more time together during the day.
- SCENARIO D (Paleoanthropology): Previous research shows that Neanderthals successfully lived in extremely cold environments during the Ice Age in Europe. Research also shows that toward the end of the Ice Age and around the time that humans (Homo sapiens) moved into Europe, Neanderthals quickly became extinct. Generate a hypothesis about what caused the extinction of the Neanderthals.
- Generate a hypothesis about what causes the observed phenomena in the scenario.
- Describe the type or types of data you would ideally collect to test this hypothesis.
- Describe what hypothetical data might support the hypothesis – for example. “The hypothesis would be supported if we found data that indicated _______.”
- Describe what hypothetical data might cause you to reject the hypothesis – for example. “The hypothesis would be rejected if we found data that indicated _______.”
- If you rejected the hypothesis, how would you refine and rewrite your hypothesis to account for your findings and begin again?
