Without diversity in the species, adaptation to the new environment is more difficult without a wide range of individuals to choose from. The evolution of humans has spanned about two million years and has resulted in the types of people we see today: people who have imperfections and people who are very different from one another. By creating a generation of genetically similar people, the human species loses its ability to adapt to changing environments. We are created to look a certain way because it will help us through life. For example, we have tail bones as we use to have tails many millions of years ago but we obviously grew out of needing them as we are not living in trees anymore it would be pointless to have a tail in our modern day lives as we now live in brick houses, not rainforests. This is why we can’t take a risk with genetically modifying our babies as we don’t know the consequences of messing with the embryos. The human species have a similar look. For example humans have organs inside their bodies as they are more protected from being on the inside. Humans also have a skull to protect their brain and same goes for the ribcage to protect the heart. If one poor child was born differently they would never survive, therefore we would never adapt to the environment around us. Furthermore, on moral grounds, whether it is believed that humans …show more content…
This might occur during the early stages such as an embryo developing something like heart disease during the pregnancy. If a doctor approaches the mother and father with the embryos and says that five out of six have a 40% chance of contracting heart disease, those five embryos will be discarded and won’t have a chance of life. This is cruel and wrong, denying poor innocent children a chance of life based on a predication that might not even come true. The child could still have a good life with heart disease. Also one should also keep in mind that there is a 60% chance of the child not developing heart disease in the first place. It is frightening that future generation is being re-designed so that the world is full of children that are identical and immune to disease instead of unique and different individuals.
In conclusion I believe that designer babies and genetically modifying children should not be allowed. All of the outcomes are worrying, such as not giving a little child the chance of life because they could develop heart disease or disturbing the natural chain of evolution. I believe that genetic engineering and designer babies should not be allowed to happen as the long term effects are terrifying and once we’ve got the ball rolling, there is no stopping it. Before we know it we’ll be ruining our future
