从行走的早期阶段开始，对婴儿和黑猩猩的双足行走发育进行了纵向研究。与成年人相比，这两个物种的婴儿都不能稳定地、有节奏地一步一步地走路。两个物种的婴儿都表现出较短的制动持续时间和较小的机械能恢复。躯干前倾，下肢关节伸展受限，加速力激活不强。势能在前进中没有得到有效利用。成年黑猩猩的行走仍然表现出向前倾斜的躯干，制动时间短，能量恢复小，参数变化大，与人类独特的成年两足动物相比。假定前两足祖先的运动特征进行了讨论。
Development of bipedal walking from the very early stage of walking was studied longitudinally in infant humans and chimpanzees. In contrast to adults, infants of neither species could walk steadily and rhythmically step by step. Short braking duration and small recovery of mechanical energy were demonstrated in infants of both species. The trunk was inclined forwards, the extension of lower limb joints was limited and the accelerating force was not strongly activated. Potential energy was not efficiently used in progression. Walking in adult chimpanzees still showed a forward-inclined trunk, short braking duration, small recovery of energy and large variance of parameters compared to the unique human adult bipedalism. The locomotor characteristics of presumed pre-bipedal ancestors are discussed.
