Linda and Lydia are identical twins born to a single mother twenty-five years ago. The twins were adopted at birth. Linda went to a family who lived in the rural west and Lydia to a family who lived in the urban south. After 20 years, the local university in the city where Lydia lived, found and evaluated the two twins as part of a twin study they conducted. Researchers were surprised to find that the urban sister Lydia was not successful in high school and currently works in a supermarket as a checkout person. Linda, who was raised in the rural west, had gone on to an Ivy League college and is completing her fourth year of medical school at the time of the interview. When Linda and Lydia met, they were eager to find out what factors accounted for this discrepancy in their levels of achievement. What is the best way to approach the issue of disparate development since their separation at birth? Utilize the information and research on the Nature versus Nurture issue to discuss what happened to the identical twins.
