  1. Summarise those features shared by humans and other primates, describe their general adaptive significance, and evaluate their contribution to human adaptation.

    Therefore, we can glean an idea of the features that are shared by both humans and primates. Yet, studies show that many of the differences between primates, especially apes, and humans are differences of degree rather than kind. By this we mean that there are very few characteristics that are not shared by primates and humans, nonetheless these characteristics have been taken much further in humans. Fundamentally humans are exaggerated primates (Introduction to Physical Anthropology, 8th ed., 2000, p.133). There are certain features that set them above other primates, yet they are not solely a human attribute.

  2. Consider how the size of animals determines and restricts their patterns of walking and similar locomotion.

    example the head of a newborn human is disproportionately larger than the rest of the body and its increase in size is less than that of the body as a whole during growth. The experimental animals that have been used to study vertebrate locomotion for a long time have been laboratory rats and mice. They are good experimental animals and have a comparable anatomy and physiology to most terrestrial mammals. This is based on the assumption that the larger species are merely scaled up versions of the smaller species.

  3. Purpose Work - The Lake District

    FMD can spread by direct or indirect contact with infected animals. Infected animals begin by excreting the virus a few days before signs of the disease develop. Pigs in particular produce large numbers of virus particles. The movement of animals, persons, vehicles and other things, which have been contaminated by the virus, spreads the disease mechanically. Airborne spread of the disease can also take place. Cattle, sheep, pigs and goats are susceptible to the disease and some wild animal such as hedgehogs, coypu, rats, deer and zoo animals including elephants.

  4. Show How Principles, Ideals and even Facts Are Corrupted By Powerful individuals to suit their own ends in ‘Animal Farm’

    However, Squealer is sent by the pigs to quell any unrest that might be brewing: 'Comrades!' he cried. 'You do not imagine, I hope, that we pigs are doing this in a spirit of selfishness and privilege?' Of course, this is exactly what the animals think, but when they are confronted in such a straightforward manner, with such a reproving tone behind the question, they cannot really reply, which gives Squealer the chance to begin his lies, which the animals believe just because they can acknowledge the fact that the pigs are cleverer than themselves.

  5. The Evolution of Man.

    These ancient ancestors also observed that not all stars move in sync. The human mind tells us a lot about the nature of science. We are shown that science is not the same thing as common sense. Common sense states how things simply are, while science explains their phenomenon and response. Also, statements of science are not always final conclusions. This is why we have different theories that are always changing and improving, for as technology advances, some theories are proved wrong or outdated (1).

  6. A Winter’s Night

    This fiendish wind soars around the forest and the impenetrable fortress that is the human's home. This icy wind batters the animal's flimsy shelter and rips it apart as if it were tissue paper. The animals stand by their wrecked homes and look on in awe as the humans begin to make their way to their luxury burrows, where they will drift off in to a heavy slumber dreaming of the warmth oblivious to the scenes of chaos outside.

  7. Compare the impacts of forest fragmentation and hunting on animal and plant species in the humid tropics. Use examples from at least two tropical continents.

    A number of predictions of the biological and physical effects of fragmentation were made by Bierregard et. al. (1992). These included that population sizes would be reduced (with harmful genetic consequences), species requiring large home ranges would not survive in small fragments and that some species would be completely lost if not already present in fragmented areas. Bierregard et. al. (1992) looked at MacArthur and Wilson's (1967) Theory of Island Biogeography in the context of a tropical rainforest rather than lands surrounded by water and suggested whilst the theory can explain the rudimentary effects of fragmentation, such as, the size

  8. Animal Experiments

    Most of the experiments done are usually to test an ingredient to find out if it is harmful to humans. They use animals to check to see whether a chemical will irritate skin or eyes. Tests like this cause animals great pain and most of the animals used in these tests are killed because they are no longer needed. It is fairly common knowledge that rabbits are used to test products for things such as allergic reactions etc. Substances are rubbed into animals shaved skin to test for adverse reactions in the draize test.

  9. To what extent are molluscs a group of specialised worms?

    As for the coelomic body cavity, molluscs do have a coelomic cavity around the heart, but this is more widely regarded as a space that the animals have evolved in which the heart can beat, than the remnants of a more extensive cavity serving as a hydrostatic skeleton. It is mostly accepted that molluscs evolved form flatworms, and probably branched off at around the same time as annelids, before segmentation occurred. They have retained a number of features linking them to flatworm ancestry - they are sometimes described as effectively being chunky worms with dorsal protective shields, but the majority of species of mollusc have diverged from flatworms in body form and lifestyle.

  10. Explain in detail how Christian and Muslim beliefs would affect their behaviour and attitudes towards the use of animals for food, experimentation and sport.

    Animals, being part of God's creation, should therefore also be protected and respected as. In Christianity there has been a growing awareness in the last twenty years concerning the rights of animals. A Catholic Archbishop said that 'God has the right to have all his creatures treated with proper respect '. Even though the Bible does teach that humanity has a superiority over the rest of God's creation, it is still believed that a 'lack of respect for the life and welfare of animals is lowering of man's own self - respect' (Archbishop).

  11. Animal Behaviour - Tinbergens Four Whys, Where are we now?

    Huxley's work established a procedure or rather a general scientific method for approaching the biological study of an organism. TINBERGEN used these three aspects, causation, survival value and evolution and with the addition of ontogeny created a general scientific method for the study of animal behaviour. However as TINBERGEN admits it is the life's work of Konrad Lorenz that made ethologists apply "biological thinking" to the field. Konrad Lorenz was a pioneer in the field of ethology, working on the development of behaviour, such as imprinting in birds; he showed that animal behaviour could be studied in fundamentally the same way as any other biological phenomena.

  12. Destruction of Natural Habitats

    For example, grizzly bears and mountain lions once roamed freely where the city of San Francisco now stands. But a wild grizzly bear or mountain lion could not survive in San Francisco today. The habitats of animals in tropical forests are particularly threatened today. People are rapidly cutting down these forests to obtain such valuable hardwoods as mahogany and teak. They are also clearing the land to plant crops.

  13. Discuss how far experimental methods on animals can be considered ethical.

    Any anxiety that the animal experiences however, should not affect the way they live and breed. In particular, endangered species unless the research is in favour of their survival. In order for this to happen, the animals must be fully understood, in terms of their needs. It is also advised that the best animal should be chosen that would suffer the least. This may include the animal that can withstand the longest period of food deprivation. Gray 1987 however, claims that food deprivation is not a form of suffering, and the rats that are used in research are fed once a day.

  14. Animal Testing.Why are so many people against it?

    All these animals helped saved hundreds of lives; their death helps us. Points of View. Animal testing, as well as human testing has found out the affects of smoking. Many humans have died from smoking related cancer and many more will do so. If animals aren't allowed to smoke because it is so harmful and cancer is imminent, why are humans? Surely by now everyone in the world knows smoking kills, yet hundreds of people do. Should I protest for the hundreds of humans forced to smoke? Do they need me to send bombs to the cigarette company owner? Should I go and protest and free them from their life of disease?

  15. Are non-human animals conscious?

    Furthermore this 'works' in the sense that on the basis of what we think other people are thinking we can predict what they are going to do - not all the time, but much better than just guessing (2). An individual that acts as if other individuals have mental states is said to have a theory of mind; when I assume you have particular thoughts and fears I am using my theory of mind. Theory of mind is more complicated than it might appear at first.

  16. Britain’s Inhumane Treatment of Animals

    Just a few years ago any cat or dog entering Great Britain was subject to a mandatory six month stay in quarantine. The justification for this quarantine was to keep Britain as the rabies free country it had become in the mid-1970s. Quarantine supporters state that a reason for state that a reason for maintaining the current system of complete and arbitrary detention of pet animals is that it is "simple." Even without including the impact on children, lower income families, elder pet owners or those dependent on guide dogs, quarantine does not appear to be "simple."

  17. Animal Cruelty – fiction

    and the LD50 (Lethal Dose 50) Test which involves force feeding a group of mice or rats until fifty percent of them are dead, hence the name. An important factor about this issue is that there is no law that states cosmetics should be tested on animals before they are released to the public, but there is a law, which was made in 1933 to protect humans from unsafe cosmetics. So it is up to the companies that produce cosmetic products whether they should test on animals or not.

  18. Compare and contrast the ways different animals respond to osmotic challenges

    The most basic osmoregulatory organ in some animals is the integument separating the organisms? internal environment from the external environment. Amphibians such as frogs have a moist and cool kin, which acts as a free water surface (Schmidt-Nielsen, 1997) where water intake takes place since amphibians do not drink (Withers, 1992). The evaporation rate is high, so amphibians generally live near water and humid environments. Because the body fluids in amphibians living in freshwater are more concentrated than the surrounding water, amphibians gain water and lose salts across the skin.
