Experimental Studies on Primate Locomotion

9806291位于纽约州立大学石溪分校的灵长类运动实验室的研究目标是确定人类和非人类灵长类的重要适应性特征，并重建古代生活方式，作为灵长类和人类起源和进化研究的组成部分。使用测量肌肉电活动、动物移动对地面施加的力、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类的摆臂、垂直爬升、两足运动和四足运动，比较和对比不同形态特征的功能作用。我们将集中于解决能量交换机制、灵长类长骨的负荷机制、身体大小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。这一结果将使我们能够理解为什么活着的猴子、猿和人类进化出不同的解剖结构，并将这种理解应用于解释灵长类化石的行为和人类的独特性。

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.
