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
One of the major causes for primate endangerment is logging. Logging, the harvesting of trees for timber, disrupts the home of many primates such as orangutans, gorillas, red colobus monkeys, howler monkeys, and chimpanzees. Even though there are specific areas that are protected by law, it is not enough to save these primates because illegal logging is very common: “Nevertheless, records for penalizing poachers are often poor, because wildlife protection is rarely a national or even local priority
discovered with an approximate total of 116 people infected in the first outbreak and 39 deaths. The Ebola-Reston is the only one of the five subtypes to not affect humans, only nonhuman primates. It first broke out in Reston, Virginia in 1989 among crab eating macaques. The Ebola virus is also a part of the Filoviridae family, along with Marburg, and contains a lipid envelope and has a single RNA strand. Ebolavirons are approximately 80 nanometers in width and vary in length. They also contain seven structural
probably immune to the virus. The University of Manitoba performed an experiment to find out if pigs were immune to the virus. The first experiment was done with piglets and chimpanzees. The piglets were then placed in a room with four cynomolgus macaques (crab eating monkeys). They were separated by wire cages to ensure that the species don’t engage in direct contact. Within a few days, the piglets showed signs of being infected by Ebola. Nine days later, all the piglets appeared to have recovered from
When it comes to animals and their rights, there is a definite line between our needs and our taking advantage of those species that we consider inferior. As long as man has existed he has been carnivorous, and the same holds true for many other species of animals. Animals are a necessity to humans for survival, whether it be for food, clothing, etc. However, the unnecessary torture of animals through testing is not a necessity for human survival. When it comes to the needless torture of animals
Y chromosome, the smallest chromosome of the karyotpe, is one of the two sex chromosomes. In 1905, Nettie Stevens identified that Y chromosome is a sex-determining chromosome, while conducting one study of the mealworm Tenebrio molitor. He also proposed that chromosomes always existed in pairs. In 1890 Hermann Henking discovered that Y chromosome was the pair of the X chromosome. All chromosomes normally appear to take on a well defined shape during mitosis when seen under microscope. This shape
