Question Detail
Question
What was the most significant trend in the evolution of modern man (Homo sapiens) from his ancestors? a. Increasing cranial capacity b. Shortening of jaw c. Binocular vision d. Upright posture
Correct Answer
Option A is the correct answer.
Detailed Explanation
While all these trends occurred, the most significant in the evolution of Homo sapiens was the dramatic increase in brain size (cranial capacity). This is directly linked to the development of complex tools, language, and culture. Upright posture (bipedalism) evolved much earlier.
Hint
The most defining feature of our species is our large brain relative to body size.
