investigate the two major theories trying to explain why do primates have large brains. Even since the seminar study of Jerison in 1973 it has been acknowledged that primate brains are unusually large for their body size. There are three main groups of theories giving more or less persuasive explanations of the evolution of large brains and high cognitive skills in primates. The first group is a group of social theories‚ postulating that primate cognition is a result of complex social interactions between

Topic 6: Mammalian Pheromones Abstract A pheromone is a chemical signal which is released by one animal and received by another‚ which induce a species specific reaction. Pheromones are detected via chemosensory systems known as the Vomeronasal Organ (VNO). Within a wide range of mammals the VNO is used to elicit a generalized sexual response‚ primarily affecting the reproductive tract. This is seen in most terrestrial mammals who have adapted to sensing volatile chemical signals; the Mouse displays

relative to the size of the individual‚ and that in females‚ aggressiveness and reproductive ability determine the rank of an individual. The dominance hierarchies displayed in primate groups suggest that higher-ranking males have the highest reproductive success due to increased female attention and availability. Female primates at a higher level benefit and are able to produce more surviving offspring‚ (Huntingford and Turner‚ 1987). In relation to Darwin’s sexual selection theory‚ Huntingford and

belongs to the group of primates‚ has great mental development with emotions‚ and interacts with their society. Some of the main things that distinguish humans from other species is their body form‚ spiritualism and their use of tools. To be human‚ one must have similar bodies and physical form to those of Primates. Unlike other species‚ humans have parts such as nimble and opposable thumbs‚ and a larger brain. One of the most distinctive abilities humans have over other primates is that humans are

In the book The Shadow of Man‚ the chimpanzees being studied are sometimes referred to as monkeys and sometimes as apes. This led me to wonder if there was in fact a difference between monkeys and apes‚ or if they were just two different ways of saying the same thing. From researching this topic‚ I found that monkeys and apes belong to the same Domain‚ Kingdom‚ Phylum‚ Class‚ Order‚ and Sub Order‚ but have a number of profound differences that show up in what Family they belong to. Apes belong

Gibbons One of the most interesting primates living on this earth is the Siamang gibbon. I first found these primates interesting while I was at the Lincoln Park Zoo in Chicago years ago because of their unique sound they make with their giant throats that sounds like a howl but has rhythm like a song. They have distinct features unlike other gibbons and they sure know how to make a scene or at least noticeable to visitors. Although my visit was very vague‚ these primates are still imprinted in my memory

The Root of Ecological Crisis 1. Human beings did not evolve from non-human primates‚ but were created in the image of God. Men and women are more than merely very complex and highly evolved apes. They possess physical attributes that are not shared by animals‚ such as an erect posture‚ hands with a highly developed opposable thumb
