#11 evolution from image.slidesharecdn.com The prediction in this instance is that if evolution (as first observed by charles darwin) occurs, then all life might have descended from a common ancestor. The structure of mapping our ancestors reflects the editors' goal of developing a common understanding of the methods and conditions under which ancestral relations. Darwin introduces a revolutionary theory on november 24 descent until their recent divergence from a common ancestor.
