Essay on The Evolution of Man - 500 Word

Humans are a product of development. Therefore human development is closely related to the origin of life and its development on the face of the earth. Talking about the development of 'man from amoeba' is customary, as amoeba is the simplest form of life. But in reality, many organisms are more primitive than amoeba, for example viruses are called. A self-replicating organic molecule is one of the most complex steps in the evolution, development from a protozoan, such as amoeba, that can consume protozoans from humans to the same time.

The term was first developed by the English philosopher Herbert Spencer for the historical development of life. Development has shown a change since then, although this term can be defined in many ways. In the context of humans, biological development began with 'the origin of life'. In the beginning, there was nothing. The successful formation of protoplasm started life and its continuous development moved towards a complex type so that different types of different types could be given birth.

About 10 billion years after the formation of the universe, the earth was formed. Life on earth was very late about three billion years ago. Of the many evolutionary problems, perhaps the origin of life is most important, because there is no record in it. Life is characterized by the ability to do some important functional activities, such as metabolic, growth and reproduction of life. There is no ambiguity about this point. But how the first life on Earth came about is a matter of estimation.

Ancient thinkers speculated that life has arisen automatically from the inorganic components of the environment, after the formation of Earth. Behind this creation a series of physical-chemical processes may have been responsible. Aristotle (384 BC to 322 BC) was the leader in this line of thought, and by the seventeenth century no one had raised any voice against his speculation. But in the seventeenth century, an Italian scientist Francesco Redi (1627-1697) used an experiment with two pieces of meat.

One of the pieces was completely covered and the second piece was placed in the open space. After a few days, they examined the two pieces very carefully. They saw that the flies placed eggs on the highlighted piece of meat and so many new flies were born. But the covered piece of meat did not make any new fly, because the flies did not have any access.

Ready tried to establish the fact that living organisms can not be automatically born from inorganic components. By studying many microorganisms such as protozoans, sperm, bacteria etc. under the microscope at the same time, Levenkoc (1632 - 1723) declared that spontaneous generation was possible for microorganisms. Later, Louis Pasteur (1822-1895) read a lot in order to present evidence in support of spontaneous creation.

In fact, scientists of this period were troubled to find out how life started smoothly in case of chance. Philosophers, thinkers and scientists had presented their various ideas and proposals about the nature and system of life on earth. Various religions had presented different concepts in this regard.
