Final answer:
Languages can provide insights into migration patterns by tracing historical movement of people between different regions. For example, the shared language between India, Southwest Asia and Europe suggests ancient migration patterns. The language spoken in Madagascar suggests migration from Southeast Asia.
Step-by-step explanation:
Languages can tell us about migration patterns by tracing the historical movement of people across different regions. For example, the map of major world language families shows that much of India and Southwest Asia share a common language with Europe, suggesting ancient migration patterns between these regions. Additionally, the fact that the people of Madagascar speak a language related to Malaysia rather than East Africa suggests a migration pattern from Southeast Asia to the island.
