Human History in DNA

Human History in DNA
In the last decade, geneticists have learned how to decode DNA in ancient human remains. We can now begin to see human history in DNA. The media has saturated us with the theory that humans originated in Africa and migrated from there to the rest of the world. National Geographic was a major promoter of that theory, and it was based on the field work of a group of anthropologists like Louis Leakey who actively defended that view. Discussions about race have also been a part of this debate among scientists, and sometimes the exchanges have been less than cordial.

The most recent debate along these lines has come with the release of a book titled Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past by David Reich. Reich runs a lab at Harvard Medical School which has released a great deal of data in the past decade. In 2010 Reich’s lab informed us that all non-Africans have Neanderthal DNA in their genome. Reich maintains that race is a social construct and that differences in genetic makeup are geographically related.

A group of 67 scholars released an open letter on BuzzFeed.com objecting to Reich’s racial concepts. Other anthropologists have contended that the reality of our origins “is more complex and interesting than scientists ever imagined.”

The biblical description of human history is so brief that one should not look for conflicts with the biblical account. The Bible tells us that we are all related, and the fact that all races are fertile with one another supports that. The Bible does not tell us when Adam and Eve lived or how much time elapsed as humans migrated throughout the world.

A careful study of the Bible indicates that we are all equal and have a common ancestry. God’s design of our genome has allowed us to survive as a species for a very long time in spite of disease. Reich’s book supports that notion but gives us some idea of how the design has worked by examining human history in DNA.
