Papers published in Science on Aug. 2, 2013, indicate that the genetic "Adam" lived between 100,000 and 200,000 years ago and "Eve" lived between 100,000 and 150,000 years ago. "Adam" is the ancestor of all living men, and "Eve" is the ancestor of all living women.
Two independent research teams analyzed the Y male chromosome sequences from men around the world to pinpoint the time the last ancestor of all men lived. One team also confirmed the time of the ancestor of all females. Other genetic studies also indicate the coexistence of mitochondrial Eve and Y-chromosomal Adam. The findings give credence both to the evolutionary model of human origins and the creationist's model recounted in the Bible of the first humans.
