Question

Quizplus · Accepted Answer

The degree of corticalization, which refers to the extent of development or wrinkling of the cerebral cortex, is the physical characteristic most closely linked to intelligence. This feature allows for a greater surface area of the brain in a limited space, facilitating more neural connections and higher cognitive functions.
