1. Why is the theory of evolution so important in understanding how human beings behave?
2. Which questions do you think evolutionary theory cannot answer?
It is important to know that the ancestors of human beings have gone through struggles and these lead to the evolutionary changes in looks, brains, and behavior. The Darwin’s theory of evolution was first introduced to me when I was studying biology in high school. His natural selection or so called ‘‘natural elimination’’ in the book DNA Consciousness was not explained as the fittest or the strongest survives but as contingently successful. DNA mutations may occur through the environmental damage, and it would either strengthen oneself of mutated into abnormality. Survival of species is undergoing temporarily struggles such as climate changes and competitions and some adaptations are better suited than others, produce off springs that carry these advantageous traits. I think it is like how we are getting pressure from the society and some of us would be more aggressive and successful than others but in genetic ways.
In the video The Genetic Connection: Rice and humans/ the 25 percent Association, describes that human shares genetic history related to Chimpanzee and we share a quarter of genes with plants and animals. Since we have a bigger brain and we are developed with stand-straight bodies with legs and hands with fingers, it is very hard to believe that we are genetically related to these animals. How did human being even begin? And it is always a controversial problem for people because in religious view human are the creation of God. ‘‘Wallace…argued that natural selection could not account for the development of human brain.’’ (Lane, 52) Why is the capacity of brains between Homo habilis, Homo erectus, Homo sapiens are different? What made human being so unique, since genome and fossils contains a record of the history of life, we are not better adapted than other species of the past, but different.
