Rebecca Cann

Rebecca Cann is a geneticist known for her groundbreaking research on human origins. She helped discover that all humans trace back to a common ancestor from Africa approximately 200,000 years ago, based on mitochondrial DNA—the genetic material passed from mothers to children. Her work provided strong evidence for the "Out of Africa" theory, indicating that modern humans migrated from Africa and spread globally. This research has significantly advanced understanding of human evolution and migration patterns.
