DNA is not necessarily a person’s destiny, but rather just a part of who they are, according to an expert. Geneticist and ancient DNA specialist Professor Turi King highlighted that DNA is merely one component of the complex makeup that defines individuals. She emphasised that people have a significant amount of agency in shaping their identities and health.
Professor King, known for leading the groundbreaking forensic DNA identification of King Richard III’s remains, stressed the intricate interplay between genetics and environment in determining one’s characteristics. She debunked the common misconception that DNA dictates everything about a person, asserting that individuals have the power to make choices that influence their well-being.
In an interview with the PA news agency, Dr. King explained, “Our DNA is not generally our destiny. It’s like an instruction manual for making a person, running that individual, and then having them go on to make their own new little people. But it’s just part of the picture of who we are.” She encouraged people to recognise the vast influence of personal choices in shaping their identities and health outcomes.
Dr. King also noted that while certain genetic factors may predispose individuals to certain conditions, the majority of health outcomes are determined by a complex interplay of genetic makeup and environmental factors. She highlighted the importance of considering upbringing, diet, lifestyle choices, and living environment in understanding health outcomes.
Speaking at New Scientist Live, Dr. King, who serves as the director of the Milner Centre for Evolution at the University of Bath, discussed the application of genetics in various fields such as forensics, history, genealogy, and archaeology. Her insights challenge the notion that DNA is a person’s predetermined fate, underscoring the significant role of personal choices and environmental factors in shaping individual identities and health.
