part of the book described observations in support of common descent. One such observation is that of the homologous structures possessed by a wide variety of animals. Darwin used the fact that lizards, bats, whales, birds, frogs cats and even humans all contain a pent dactyl limb to support his theory that all life is descended from one common ancestor. As he says himself , “What can be more curious than that the hand of a man, formed for grasping, that of a mole for digging, the leg of the horse

what is the theory of evolution. The theory of evolution suggests that all the living organisms in this world fo through a process of natural selection (survival of the fittest per say) in order to have the most beneficial genes carried on. This was proposed by Charles Darwin also known as the father of evolutionary psychology, then again John Bowlby was the first to come up with such theory. How is this linked to behaviour? In essence if a certain behaviour exists in humans(or other) today , then

Is Evolution Possible? Evolution is highly improbable because by definition evolution is the naturalistic explanation of the origin of life that includes an account for the origin of elements, missing links, and laws of nature. Our bodies need 25 elements to live. (Schirber). Ninety six percent of the body is made up of four chemical elements; oxygen, hydrogen, carbon, and nitrogen. (Schirber). Without hydrogen a person may live three to five days. If no oxygen is present within four minutes permanent

Mapping genomes and comparing them to other mammals, birds and reptiles (2) C. New fossils showing the evolution history of the platypus Improvement: A. Evidence that the platypus keeps a constant body temperature of 32oC which is a feature of mammals (2) B. Enhanced the understanding of the evolution of genes in humans and other mammals (2) C. Platypus like monotremes fossils from the Mesozoic Era, found in Australia suggest that they originated and were found

Most of us think about evolution in some prehistoric sense. After all, we were first exposed to the theory of evolution in elementary school studying about dinosaurs. But evolution has not stood still; it has been an on-going process. There are many contributing factors to micro and macroevolution. Microevolution therefore refers to changes in DNA within a population for adaptation. Scientists have uncovered a gene BMP4, which shapes the beaks in Galapagos Finches. According to Weiner the finches

similar looking to humans in their physical appearance. They are even considered to be humans, before we humans came along. When we humans are compared to Neanderthals we are considered to be modern humans. The extinction of Neanderthals could have been caused by many reasons. But scientists believe that the cause of extinction is due to evolutionary forces. There are a few evolutionary forces that may have taken place in the extinction of the Neanderthals. But if we, modern humans, are still alive

reactionary racial politics that already prevailed. Darwin endorsed an inevitable inequality among men and the races of men that no philanthropy ought to eliminate. This theory stressed the necessity for human intervention to improve the race thought better breeding. Eugenicist compared good human stock to thoroughbreds equating the wellborn with superior ability and inherited fitness. Pseudoscience, masquerading as hereditary science, provided Americans

survive. For example, even though some prehistoric animals (I.e. dinosaurs) were extremely large and powerful, their brain capacity and mental ability were so limited that they did not survive, whereas smaller and more intelligent beings, such as human, did. Darwin suggested that this process of natural selection essentially has nothing to do with freedom. He believed that it is nature that governs, through its various processes, the makeup, strength, and survival potential of the various species

The Natural Selection Process of Evolution “Darwin Island” and “Wallace Island” finches have survived many years on these isolated islands without much help from the human population. They are able to survive by adapting to their surroundings by a process called evolution. The evolution process begins with a process called natural selection. At this time, both islands are around the same size and the finches have similar populations and beak sizes. What would happen in 200 years if the “Wallace

purpose of the biological perspective is to determine the physiological basis of psychology and most importantly behaviour. The perspective primarily uses the experimental method and has been criticized for being too reductionist and for using non-human animals. Strengths By knowing the physiological basis of behaviour we can treat symptoms with drugs evolutionary theory can explain things that would otherwise be unexplainable Weaknesses It is difficult to seperate genetic influence from environmental
