Twin Studies with Prof. Nancy Segal | Newsfirst, Sirasa TV
Professor Nancy Segal, a leading expert in behavioral genetics, discusses what twin research reveals about human nature in this interview broadcast on Newsfirst, Sirasa TV. Drawing on decades of study, including the remarkable story of the “Jim Twins,” identical twins separated at birth who unknowingly mirrored each other’s lives, Prof. Segal explores how genetics shapes personality, behaviour, and life choices, even across vastly different upbringings. While genes are influential, she emphasises that environment still matters, and that understanding our genetic predispositions can help us make better choices. The interview also touches on the ethics of twin research and what these studies ultimately reveal about the enduring question of nature versus nurture.
