Anthropologists can learn the following by studying genetic evidence:
-
The region that native groups occupied: Genetic evidence can provide insights into the historical distribution of populations and their ancestral homelands.
-
How native groups migrated: Genetic markers can trace migration patterns of populations over time, revealing routes and timelines.
-
How people from different native groups interacted with each other: Genetic evidence can indicate gene flow between populations, suggesting interactions such as trade, intermarriage, or conflict.
-
When various groups of native people split off from each other: Genetic analysis can estimate divergence times between populations, helping to understand when different groups became distinct.
In summary, all the options listed can be learned through the study of genetic evidence by anthropologists.
