Vedclass · Answer

(C) During human evolution,several anatomical changes occurred to support an upright posture and bipedal locomotion. $1$. The cranial capacity increased significantly to accommodate a larger brain. $2$. Bipedal locomotion (walking on two legs) became the primary mode of movement. $3$. The pelvic girdle broadened to support the weight of the upper body in an upright position. $4$. Conversely,the forelimbs shortened,not lengthened,as they were no longer needed for weight-bearing or locomotion,allowing for greater dexterity and tool use. Therefore,the lengthening of forelimbs is not a characteristic acquired by humans.

Which of the following characteristics was $NOT$ acquired by man in the course of evolution?
