Meiosis is also called litotes. This is a process by which there occurs cell division. The result is ‘four daughter cells’ with chromosomes that number half of what the parent cell had. This process has two main phases; one, ‘interphase meiosis 1’ and two, ‘interphase meiosis 2. Both these processes are cell division processes. The first interphase involves the cells duplication process while the second interphase involves the crossing over o the divided cells (Belk, 2010).
Over the years, scientists have endeavored to study the human system. Bones and fossils, as well as DNA have been continually studied so as to provide the needed knowledge in the understanding of the human body. In chapter 7 of Belk’s book, ‘Are You Only as Smart as Your Genes?’, the scientists and author attempts to study the role of genes in our bodies. He says that both the intellectual and physical endowment goes back to our genetic make up. He further gives evidence of a person with characteristics such as hairy nose and great IQ. The scientist argues that everyone should thank their DNA for everything they have. Therefore, the process of meiosis plays a huge part in what our genetic make consists since it is through it that people get their DNA. This is the evidence that he gives (Belk, 2010).
On the other hand, Bajd in his book ‘Where did we come from? Current views on human evolution’ says that evolution is what is responsible for the genetic make up of people. He uses Charles Darwin’s theory to disapprove Mekl’s theory of genetics. Both men attempt to explain the human body (Bajd, 2008). Skin color, bipedalism and even facial structures can be explained by meiosis and evolution. Thus, mutation of the human gene is responsible for the kind of population that the community has. How and when mutation occurs is also described. The human population has benefited a great deal from mutation. The healthier and better genes have been passed from one generation to another whilst the weaker ones have been discarded. This has made the population healthier than their prior generations. Personally, I do not believe in mutation. My religion considers Allah the only source of life and health.
