Who is the U of M researcher who studied identical twins separated at birth?
Correct Answer:
Thomas Bouchard
Explanation:
This question tests knowledge of a landmark study in behavioral genetics that uses identical twins separated at birth to explore nature versus nurture. The U of M researcher who led this work is Thomas J. Bouchard. He directed the Minnesota Twin Study, which followed identical twins raised apart to see how much their traits reflect genetics versus environment. The research famously highlighted strong genetic influences on many aspects of personality, intelligence, and interests, shown by striking similarities between twins reared apart, alongside the clear role of environment as well. The other figures listed are known for different work: Watson and Crick revealed DNA's structure, and Jung is associated with analytic psychology, not this twin-study research.
