Natural Selection Vs Evolution

Mankind has always wondered how and why they came to be. Upon further discoveries throughout time from modern humans, the majority of scientists would agree that man evolved from a common ancestor in the span of thousands of years. In recent human history some people would suggest that humans have stopped evolving due to advancements in technology and medicine. Even though humans have certainly gained more knowledge, there are still forces of evolution that cannot be stopped. These forces include; genetic drift, gene flow, and natural selection. Thus, by observing these principles in Darwin’s theory of evolution, it is reasonable to assume that the natural evolution of the human species will continue. Genetic drift is always occurring in
Natural selection involves animals that are better adapted to their environment which helps them survive to reproductive age in the hopes that they create offspring. Regarding modern humans, natural selection takes various forms since they are the apex predator. In strictly environmental terms, climate change will affect those that are not adapted to their changing environment. For example, rising temperatures and more sun radiation could give people with darker skin an evolutionary advantage of fair-skinned people. Skin cancer may arise more in fair-skinned people which could cause more deaths. Due to their unfavourable traits, natural selection would select against fair-skinned people. There is also the social environments that one must consider when dealing with natural selection. Humans are shallow animals which is all a part of their instincts. There is a pre-existing sensory bias on how humans perceive beauty. Subconsciously, many people find certain traits and appearances to be more beautiful than others. But, certain cultures may find certain qualities to be more favourable. For example, if a certain culture favoured more taller men regarding potential mates, then the shorter would be a disadvantage. The social environment would be deemed as non-ideal for the shorter men which would hurt their chances of sexual reproduction and more. Natural selection would be working against those not adapted to to their environment, the shorter men, in this case. But natural selection can be affected by other factors, too. The direction in which traits are favoured can change over time depending on the changes in the environment. For example, if the majority of men in a certain area had clean-shaven faces, then the rare appearance of men with bearded faces could trigger a change in sexual selection. The scarcity of men with beards could give them a sexual advantage which would help
