Final answer:
The answer to the question is false. Cerling concluded that it is still unclear how human ancestors chose locations for their habitats. This conclusion is supported by evidence such as the existence of Paleolithic shelters like caves and the impact of changing global climate conditions on human migration.
Step-by-step explanation:
The question is asking whether it is true or false that from the study of paleoenvironments, Cerling concluded that it is still unclear how human ancestors partitioned their time between more open and more closed habitats.
The answer to this question is b. False. Cerling actually concluded that it is still unclear how human ancestors chose locations for their habitats based on factors like defense against predators and rivals, and protection from inclement weather.
This conclusion is supported by evidence such as the existence of Paleolithic shelters like caves and the impact of changing global climate conditions on human migration.
