I read a recent on-line article about science journalist Steve Olson, who has developed a computer program to determine how far back we would have to go to find a common ancestor for all people. Taking into account population changes over time, accepted past population growth rates, and a range of migration rates, Olson and his co-laborers determined that we would have to go back 5,000 to 7,000 years to find this single common ancestor!
Interestingly, if you go through the Bible and take note of the dates throughout, Adam and Eve would have walked this earth about 5,000 to 7,000 years ago. Makes you think, doesn't it?
