The Evolution of Primate Locomotion and Body Configuration
Primates first evolved from the trees of tropical forests, later to the ground. Through the times of promisians to human, many characteristics has been represented due to the adaptations to new environments and resulted in evolutionary changes. The Earth has encountered several geological and climatic changes over time. For the primates existed at that time had to adjust itself especially in body configurations and locomotion in order to better survive. It is important to be aware of this information since we are the part of occurring changes as well. Throughout the evolution owing to

They have nails in all digits except for the grooming claw on the second toe. Their arms tend to be shorter than their legs, and they have strong hind legs for jumping, storing the elastic energy, which allows them to jump up to 6.6 feet.

Grade II – Tarsiers The second grade of primates evolved about 53 million years ago, in Eocene epoch. There are five tarsier species that all live in the islands of Southeast Asia, where they inhabit from tropical forest to backyard gardens (Jurmain, et al, 2011). They are considered to be closely related to lemurs and lorises (prosimian family) for the several traits that they share with Grade I primates while having some anthropoid features as well. However, tarsiers have distinctive characteristics that isolate them from other primates. They are categorized as the smallest creatures among the primate species and they are well known for their enormous eyes which is as large as its brain. They are normally nocturnal insectivores but sometimes carnivorous. They catch insects by jumping at them and as they jump from tree to tree, they even hunt for birds while in motion. The body size grows from 4 inches to 6 inches. Being one of the smallest primates, they comparatively have large hands and feet that
