Leaping as locomotion The fossil record shows us that tarsiers have developed very elongated tarsals, and hind limbs (Rasmussen et al 1998). When comparing the fossil morphology to that of extant lineages of tarsier we can infer that these exaggerated features observed in the post crania have allowed for a powerful, quick movement that is highly adaptive and advantageous to predation avoidance strategies in the tarsier lineage. When observing extant tarsiers it has been recorded that upon detection
species. For 23 species with sample sizes of nine or more for each sex, dimorphism (male/female ratio) in neonatal body mass range from 0.94 in Galago senegalensis 1.19 in Pongo pygmaeus. Dimorphism in neonatal body mass was absolutely connected both with adult body mass and with dimorphism in adult body mass, but the obvious relationship with adult
Hello Coach Willaim’s, i am going to tell you about African savannas. Im at The savannas in Kenya, Africa. Savannas have warm temperature throughout the year. There really isn't a difference in the Savannas seasons. Savannas has a very long dry season which is during the winter, and a very wet season which is during summer. Between the months of December and February there will be no rainfall at all. The dry seasons will only have an average around 4 inches of rainfall. The Savannas climate temperature
The Evolution of Primate locomotion and body Configuration After millions of years that humans separated from their relative primate how is that humans became bipedal. So many changes have happened to the human body to decide to stay on the ground and abandoned their lives in the trees. Primates evolved different body structures according to their lifestyle and the ecosystem in which they lived. As Charles Darwin natural selection stays; it could be as a result of new environments, the need for food
Monkeys are haplorhine primates, a group generally possessing tails and consisting of about 260 known living species. Many monkey species are tree-dwelling (arboreal), although there are species that live primarily on the ground, such as baboons. Most species are also active during the day (diurnal). Monkeys are generally considered to be intelligent, particularly Old World monkeys. There are two major types of monkey: New World monkeys (platyrrhines) from South and Central America and Old World
The Mbuti Pygmies in the Ituri Forest The Mbuti Pygmies in the Ituri forest in central Africa are foragers who use a combination of foraging, net hunters, and archers. Their kinship, social organization, and gender relations make them a unique band. Even though they live in the rainforest of equatorial Africa with hardly any possessions, they are happy, peaceful people. The pygmies are small people who are typically less than five feet tall. The Mbuti have lived in the Ituri forest for many thousands
