Watch the video about two twins separated at birth.
Twins: Is it All in the Genes? Nature vs. Nurture
Dr. Nancy Segal has studied reunited twins for more than 30 years. With Lisa Ling acting as her research assistant, together they interview twins Linda and Doreen, who spent 35 years apart. The results of their interviews will help science understand the effects of nature vs. nurture on traits present in each twin.
What does this video make you think about the impact of environment on personality? The impact of heredity?
