Evolution theories
There are myriads of theories that have, in the past, to the present-day been used to explain the phenomenon. Evolution theory is one of the common premises put forward to explain the origin of human beings and other species. Even though other theories have been put forward to explain this, I do not believe in theories. Hence, I believe that we cannot believe in them. Herein I explain why we cannot believe in theories, especially based on shortcomings of the widely known Darwin theory of evolution using the theory of lactose tolerance I some populations.
Evolution supports the theory that genetic changes, which are sometimes influenced by environmental changes and cell changes, drive a change to the phenotype and genotype properties of a person. However, evolution fails to explain the theory of lactose intolerance. A certain population such as the Burundi of East Africa can readily digest milk in large quantities while other populations such as the Yoruba cannot, and this symptomatically shows with diarrhea, constipation and in severe cases.
This type of biological trait cannot be explained by genetics because evolution would see that the body genetically evolves to curtail lactose intolerance as a disadvantageous trait. After all, for all humans, the production of the lactase should increase after weaning. What this means is that human biology often changes even without a change in the genetic makeup of an organism.
Conclusively, theories in general, especially evolution theories, cannot be used to explain life. Theories are just hypotheses that test alternative differences between events and organisms. What we know is that the environment we live in changes, so do we, but none of these theories are worth believing in because explaining what is complex has always been man’s greatest desire. .
