Examining the question, we are asked to identify which option reflects evolutionary support for the adaptive role of hyperactivity and restlessness.
Option A suggests cross-cultural variation in ADHD rates among adolescents; while variation can be informative, this alone does not establish adaptive evolutionary support for hyperactivity or restlessness.
Option B states that DRD4-7R gene mutation is more common in migratory cultures. This aligns with the idea that certain genetic traits associated with exploratory or restless behavior could have been advantageous for groups that migrate, providing a potential evolutionary basis for such behaviors in specific contexts.
Option C proposes increased survival and life expectancy for children with ADHD. Although this would imply some fitness advantage, there is limited evidence consistently showing higher survival or life expectancy linked to ADHD; in fact, ADHD is often associated with challenges that can reduce fitness in some contexts, making this claim less robust as foundational evolutionary support.
Option D mentions identification of the DRD4-7R gene mutation in over 30% of the human population. That prevalence would raise questions about whether this variant is truly advantageous or whether it is nearly neutral or widespread due to other factors; moreover, such a high prevalence is not accurately characterized in the literature as supporting a direct adaptive role for hyperactivity/restlessness.
Option E reports a link between the DRD4-7R gene mutation and environmental adversity. Although gene-environment interactions are important, this option frames the mutation as associated with adversity rather than as an adaptation linked to migratory or exploratory behavior; it does not directly describe an adaptive advantage in the context of movement or restlessness.
Overall, the reasoning behind evolutionary interpretations often focuses on whether a trait could have conferred a historical fitness advantage in particular ecological contexts, such as migratory lifestyles, which makes option B the most plausible candidate among the choices given. The remaining options either overstate prevalence, misstate fitness implications, or do not tie the genetic variant to an adaptive migratory context as clearly.
Note: The evaluation here considers how each statement would support or fail to support an adaptive interpretation of hyperactivity and restlessness in an evolutionary framework.
