Short Answer Questions
Q6. Why are humans classified as primates? Mention one shared feature with other primates.
Q7. Briefly explain what the "Out of Africa" hypothesis proposes about the origin of modern humans.
Q8. What is bipedalism, and why is it considered an important evolutionary development in human ancestors?
Q9. Name any two early hominid species that are considered part of the evolutionary lineage leading to modern humans.
Long Answer Questions
Q10. Describe the general evolutionary timeline of human evolution, from early primate ancestors to modern Homo sapiens, mentioning key stages and their features.
Q11. Discuss how factors such as increasing brain size, bipedalism, and tool use are believed to have influenced the course of human evolution.
APPLICATION / ANALYSIS
Q12. Fossil evidence shows a gradual increase in brain capacity across successive hominid species, from early Australopithecus to modern Homo sapiens, along with increasingly sophisticated tools found alongside their remains. Explain how these two trends (brain size and tool complexity) might be biologically and evolutionarily connected.
Q13. A student wonders why modern humans, despite having descended from ancestors similar to today's apes, are so anatomically and behaviourally different from chimpanzees, even though we share a fairly recent common ancestor. Using your understanding of human evolution, explain how millions of years of divergent evolutionary pressures could account for these differences.
