A Human And A Chimps Opposable Thumbs. Modelling a muscle key to flexing the thumb, a new study suggests that the powerful opposability that characterises the dextrous. For example, like most primates, chimps retained their “thumbs” on both their hands and feet. The human opposable thumb is longer, compared to finger length, than any other primate thumb. While chimpanzees grew longer fingers and slightly shorter thumbs, well adapted to their tree climbing lifestyles, humans. All to some degree possess prehensile (grasping) hands and all (except humans) prehensile feet. Colobus monkeys have greatly reduced the thumbs on their hands, because these. The critical component of the prehensile hand is the opposable thumb. This image diagrams the difference between human and chimpanzee models of thumb muscles, which the researchers used to study. This long thumb and its ability to easily touch the other fingers allow humans to firmly grasp. The killer app in the evolution of our hands was our opposable thumbs, which allow humans to precisely hold tiny things between our fingertips and pad of our thumb. Here the authors show that hand proportions vary greatly among ape species and that the human hand evolved from an ancestor.
