Scientists Used Mitochondrial DNA to Investigate Patterns of Human Evolution

Scientists used mitochondrial DNA to investigate patterns of human evolution.Which description is a result of this research?

A) Humans first evolved in western Africa 200,000 to 150,000 years ago.
B) All humans alive today are related to a single female ancestor.
C) All humans are related to "Eve," who was the only female human living approximately 200,000 to 150,000 years ago.
D) "Eve" was the only female who was reproducing approximately 200,000 to 150,000 years ago,so she was the only one to leave human descendants.
E) "Eve" lived in eastern Africa approximately 200,000 to 150,000 years ago,and she migrated from there into central Europe and founded a new ancestral population.
