n the modern biology, biologists and scientists tend to make experiments on animals in order to find the human nature. A myriad of people think that it is of no benefit for humankind to study animals. But others hold an opposite attitude. From the perspective of the evolution of human being, I hold the opinion that it is definitely valuable for people to make a research on animals taking into account for the further development and exploration of human being. My arguments are listed as follows.
I agree with the statements above without reservation since there is the similar biological structure between mankind and animals. According to the theory of evolution, human beings are stemmed from the further prehistoric animals in billions of years. It is universally acknowledged the truth that there are numerous similarities between mankind and chimpanzee. A variety of survey results are obtained from the researches on the chimpanzee or primitive animals. For example, throughout the observation and research on the chimpanzee, scientists found a great deal of human nature possessed by these primitive animals such as chimpanzee and monkey. For instance, scientists had suspended a bundle of bananas on the ceiling of house, put a long stick on the ground, and observed how chimpanzee reach the fruit. The chimpanzee tried its best to reach the banana but failed. At this time, the chimpanzee saw the long twig on the land, picked up the stick to reach the cluster of bananas and successfully get them. Based on this experiment, scientists are able to find its ability, similar to the human being, for chimpanzee to know how to use tools. By this experiment, it is conducive for people to make the further research on the capacity of mankind,
Another reason for my point is that the study of animals contributes to the comprehensive understanding of human nature. A fair proportion of animals have the same organization in their structure. It is of great help for the research on human nature to do the tests on the animals. As we all know, mammals have all the brain cells. Scientists made an experiment on the little mouse so as to perceive the brain cells. They allowed the little mouse to keep active around the clock. And after a period of time, scientists found the fact that the brain cells of the little mouse died out with a rapid speed. Eventually, biologists and scientists arrived at the conclusion that people are inclined to die early because over exhaustion would kill more brain cells. In short, human being benefit significantly from the study of animal.
In a word, from what has been discussed above, we can draw the conclusion that the study of animals significantly contributes to the exploration of human nature. 作者: jimibt 时间: 2008-12-5 13:42:37

总得来说，表达方面问题不大，但是例子的支撑不太够，另外我对human nature的理解也与楼主意思不一样，楼主的作文第3段侧重于生理上，而我认为侧重于心理上，社会上。根据wiki中human nature解释
Human nature is the concept that there are a set of characteristics, including ways of thinking, feeling and acting, that all 'normal' human beings have in common.The branches of science associated with the study of human nature include sociology, sociobiology and psychology, particularly evolutionary psychology and developmental psychology. Philosophers and theologians have also carried out research on human nature.
