Q. What was the most significant trend in the evolution of modern man (Homo sapiens) from his ancestors ?

AIPMTAIPMT 2011Evolution

Solution:

The most significant trend in the evolution of modern man (Homo sapiens) from the ancestors is increasing brain capacity. The human species developed a much larger brain than that of other primates-typically $1,330 cm ^{3}$ in modern humans, over twice the size of that of a chimpanzee or gorilla.
