• Enlargement of frontal region supported development of high forehead and chin

Answer 1

An increase in cranial capacity over time, especially the enlargement of the frontal region, supported the development of a high forehead. Combined with the development of the chin, these features became characteristic of modern human facial structure and reflected increased brain size and cognitive abilities.
