Darwin's Theory Of Natural Selection Essay

Darwin’s “Theory of Natural Selection” is described as being the process behind evolution. In the theory, an environment is essentially selecting which species will do well within it through different natural events. Individuals within a population differ, and the differences between the species are passed from parents to their offspring. Some individuals are more successful at surviving and reproducing than others, and the successful individuals succeed because of the favorable traits they have inherited. We can look at a giraffe for an example of Darwin’s theory, because a giraffe born with a longer neck has an inherent ability to reach for more food when compared to a giraffe with a shorter neck. This causes the giraffes with longer necks

This practice holds the ability to eliminate potential diseases and disabilities that a child could be born with before the child is actually born. This concept seems like an advantageous idea, but parents who chose to “design their baby” are also able to program what physical and personality traits they want their child to have. Evolution could be harmed severely if humans begin populating our earth with these “designer babies.” In lecture, I learned about evolution and how environments essentially select which species will do well within it through different natural events. If these modified humans existed, there would be less diversity in the human population which would make it harder for these humans to adapt to new, changing environments. It is imperative that there is a substantial range of individuals in a species in order for that specific species to continue to be competitive with each other and thrive in their communities. The concept of individuality would no longer exist if genetically engineered humans roamed the earth because everyone would look the same and share the same personalities which would make for a very boring
