Question
What changes in the chin and brows have been seen during the course of human evolution?
✓
Answer
There have been several changes in the chin and brows throughout human evolution. The chin is a unique feature of the human face that is absent in other primates. Scientists believe that the chin may have evolved as a result of changes in our diet. In contrast, changes in the brow ridge have been seen throughout human evolution, with earlier hominids having more prominent brow ridges as compared to modern humans.
