Experimental Studies on Primate Locomotion

9806291 纽约州立大学石溪分校灵长类动物运动实验室的研究目标是识别人类和非人类灵长类动物的适应性显着特征，并重建古代生活方式，作为灵长类动物和人类起源和进化研究的组成部分。使用测量肌肉电活动、移动动物对地面施加的力、肢体节段的 3D 位移和速度以及骨骼内应变的技术，我们将分析猴子和猿的手臂摆动、垂直攀爬、双足运动和四足运动，比较和对比不同形态特征的功能作用。我们将重点关注解决能量交换机制、灵长类长骨的负载机制、体型对运动参数的影响以及陆地四足动物的替代策略等问题的项目。这些结果将使我们能够理解为什么现存的猴子、猿和人类进化出了不同的解剖结构，并将这种理解应用于对化石灵长类动物行为和人类独特性的解释。

9806291 The research goals of the Primate Locomotion Laboratory at SUNY, Stony Brook are the identification of adaptively significant features in humans and nonhuman primates, and the reconstruction of ancient lifestyles, as integral components in the study of the origin and evolution of primates and humans. Using techniques that measure electrical activity of muscles, forces exerted on the ground by moving animals, 3D displacements and speed of limb segments, and strain within bones, we will analyze arm-swinging, vertical climbing, bipedal locomotion, and quadrupedal locomotion in monkeys and apes, comparing and contrasting the functional roles of different morphological features. We will focus on projects that address questions of energy exchange mechanisms, loading regimes of primate long bones, the influence of body size on locomotor parameters, and alternative strategies for terrestrial quadrupedalism. The results will enable us to understand why living monkeys, apes, and humans have evolved different anatomies, and to apply that understanding to the interpretation of fossil primate behavior and the uniqueness of humans.
