SCENARIO D Anthropologists have been studying Y-chromosome DNA to understand where and when humans first appeared and when they moved into other areas of the world. The Y chromosome is found only in males, and most of the DNA found on the Y chromosome is passed directly from fathers to sons. Researchers collect Y-chromosome DNA information from men today and compare the amount of difference seen in the DNA. Greater amounts of genetic difference indicate longer periods of separation between different groups of people because it takes time to accumulate genetic variations. This Y-chromosome DNA research has helped anthropologists to understand our species’ origin in Africa and our various migrations to other parts of the world.
What is the primary field of anthropology addressed in this research?
(A) Archaeology
(B) Biological anthropology
(C) Cultural anthropology
(D) Linguistic anthropology
