Answer:
Scenario A
- C. Palaeoanthropology.
- B. Biology.
Scenario B
- D. Primatology.
- D. Psychology.
Explanation:
Scenario A
Palaeoanthropology is the study of hominization to see how humans developed to be anatomically similar to modern humans from their more apelike ancestors so this study would fall here.
Biology is the relevant discipline as it relates to the study of living things and their characteristics.
<em>This research relates to human evolution because it can shed more light on how humans went from being apelike and climbing trees to being able to walk upright. </em>
Scenario B
Primatology is the study of primates like chimpanzees so this research would fall under this anthropology subject.
The relevant discipline would be psychology as it might shed light on how the chimps knew to make tools to be able to hunt galagos.
<em>By researching this subject, we can find out how early humans began to make tools for hunting as well as their motivation to do so. </em>
