The Two Suborders of Primates. 1. Prosimii Rely more on smell than other primates have mobile ears (like a cat) whiskers snouts fixed facial expressions Many of these species are nocturnal and arboreal. (less emphasis on vision) 2 major groups: Loris-like forms (Loris and Galagos (bush babies – see below)) eat fruit and bugs Mostly live in southeast Asia. Lemur-like forms. Lemurs all from Madagascar. An ancestral population underwent adaptive radiation (geographically

The cloning of any species‚ whether it be human or non-human‚ is ethically and morally wrong. Scientists and ethicists have debated the implications of human and non-human cloning extensively since 1997 when scientists at the Roslin Institute in Scotland produced a cloned sheep named Dolly. No direct conclusions have been made‚ but strong arguments state that cloning of both human and non-human species results in harmful physical and psychological effects on both groups. I will address the issue

The Tarsier is a very elusive creature because it lives in such a small area of the world. It has the largest eyes to body ratio of any primate. Because of the immense size of their eyes that do not swivel in their sockets and the tininess of their body‚ the tarsier looks like something out of a Hollywood extraterrestrial movie and is often described as “the littlest alien” (Tarsier: The Littlest Alien). The tarsier inhabits the Philippine islands of Southeast Asia. These areas are covered in tropical

Ugly In this paper‚ the writer will take on the persona of one of the strangest primates in the world – the Aye-aye. Found only in the forest of Madagascar‚ this unusual creature said to be closely related to chimpanzees as well as humans is a nocturnal primate under the family of lemurs (Daubentonia madagascariensis). Considered to be giants compared to other lemurs in the island of Madagascar‚ what makes this primate interesting to talk about is its unique yet strange physical features that in most

most humans‚ the idea that we are in no way similar to the great apes. Though there are many biological and social differences between Homo Sapiens and the great apes‚ who are all members of the Hominoidea Infraorder‚ (a sub-classifaction of the primate order within the animal kingdom) there are also many similarities. When comparing Homo Sapiens and great apes‚ there is a lot to compare biologically. Humans differ from the great apes in a few ways. For instance‚ humans are bipedal (the ability

Characteristics Skull of an Oriental giant squirrel (genusRatufa) - note the classic sciuromorphousshape of the anterior zygomatic region. Squirrels are generally small animals‚ ranging in size from theAfrican pygmy squirrel at 7–10 cm (2.8–3.9 in) in length and just 10 g (0.35 oz) in weight‚ to the Alpine marmot which is 53–73 cm (21–29 in) long and weighs from 5 to 8 kg (11 to 18 lb). Squirrels typically have slender bodies with bushy tails and large eyes. Their fur is generally soft and silky

Even nonhuman primates such as monkeys and chimpanzees need social contact with others of their species in order to develop properly. As we will see‚ appropriate social contact is even more important for humans. -Isolation and Nonhuman Primates Researchers have attempted to demonstrate the effects of social isolation on nonhuman primates raised without contact with others of their own species. In a series of laboratory experiments

Anthropology • The Human Species has evolved from numerous primates throughout the past millions of years through natural selection • Natural selection: Organisms that best adapt to their environment to survive produce offspring. • Through natural selection humans have characteristics that make them Unique • Humans are the only mammals that are bipedal • Bipedalism: using two legs for walking • Other primates such as chimpanzees‚ and gorillas have the ability to walk bipedally
