Dr. Dan Reynolds continues on the topic of the origin of humans. Dr. Reynolds corrects the misstatements that our DNA is similar to that of chimpanzee DNA. He also presents the evidence that the population of the entire modern world is descended from a single human male, based on the occurrence of only a single type of Y chromosome, and from 3 females, based on the 3 basic varieties of mitochondrial DNA. Based on measured mutation rates of mitochondrial DNA and the extent of variation imply a common ancestor for all of the world’s population from a common ancestor only several thousand years ago. These observations are consistent with our descent from Noah’s three sons and their wives.
