The Theories of Evolution Study

When it comes to the theories of evolution, a few of them are appreciated and believed. First, Lamarckism us the theory of the inheritance on acquired characters, and it was developed by Lamarck, a famous French naturalist. It’s based on comparisons between modern species and fossil records, and it believes in inheriting acquired characters that are defined as certain changes developed in organisms from normal characters as a response to different environmental changes or their functions. Lamarck also claimed that the adaptation was an effective tool of evolutionary modifications. Besides, this theory of evolution revived as neo Lamarckism based on the latest findings in this field that confirmed that the environment influences the color, structure, forms, and size of organisms.

Darwinism is the most popular and well-known theory of evolution developed by an English naturalist Darwin who is called the most powerful figure among biologists. His extensive study of the nature plays a huge role, and he gathered many observations on relationships between extinct and living animals. He states that existing living forms have similar characteristics with other life forms that existed in the past. The main idea of Darwin is that each population builds its own variations in its characters, and all living organisms keep struggling to survive because of their ongoing reproductive pressure and limited natural resources. Darwin also believed that all existing organisms, including human beings, are the modified and changed descendants of previous forms of life.

The mutation theory of evolution also deserves students’ attention, and it was offered by Vries, a talented Dutch botanist who stated that any evolution is not a continuous process and it happens because of specific mutations. According to his arguments, experiments, and findings, this theory suggests that evolution is quite a jerky process characterized by jumps from one species to others, and this means that new species arise from the pre-existing ones in their single generation.

Finally, there is a synthetic theory of evolution or neo Darwinism, which is a modified and improved version of the above-mentioned theories that are not fully satisfactory. They claim that the importance of different populations as evolution units and the role of their natural selection are the basic elements and mechanisms.
