Answer 5

Certainly! Let’s review the questions and answers again:

1. Regarding Homo sapiens: The correct belief among scientists is that "They arose in Africa and spread to the rest of the world." This aligns with the predominant "Out of Africa" hypothesis in paleoanthropology.

2. Regarding what a scientist studying fossils would examine: The most appropriate choice is a skull fragment. Fossils typically refer to preserved remains of organisms, which can include bones, teeth, and other hard parts of animals. In contrast, pottery, cave paintings, and tools made of bone would be associated more with archaeology rather than paleontology, which specifically focuses on fossils.

Both answers provided are accurate and align with current scientific understanding. If you have any further questions or need additional clarification, feel free to ask!
