'To what extent does DNA shape our future?' asked the commentator in a recent BBC series on human biotechnology.
Each cell in our body has 46 chromosomes that carry digital information embedded in a molecular structure known as DNA. A scientist assured us with enthusiasm that the DNA 'contains all the genes needed to make a human.' We were informed that 'everything about us is determined by DNA'.
What are Christians to make of this? Many will know that there has been a nature/nurture debate running for decades, but is it correct to say that the 'nature' argument has been vindicated by genetics? Furthermore, if our behaviour is controlled by genetics (and consequently by complex molecules within us), where does that leave Christian teaching on human responsibility for our thoughts and actions?
