The End of Human Evolution
Debate Rounds (2)
According to Darwin's theory, individual animals best suited to their environments live longer and have more children, and so spread their genes through populations. This produces evolutionary changes. For example, animals that could reach the juiciest leaves on tall trees and therefore tended to eat well, live longer, and have more offspring. Eventually, some animals evolved to have longer neck, and those with shorter necks died out.
Evolutionary "dead ends" happens when an organism and its environment come into equilibrium or if the organism dies. At this point, any additional evolution is unnecessary. Humans have the distinct ability to change their environment. If a person does not like their environment, he can simply move away. In addition, the technology of the 21st century eliminated the need for evolution. With a little ingenuity, people can create tools to cover shortcomings. For example, humans on their own cannot travel great distances in a short period of time. However, with tools, such as bicycles, automobiles and planes we can travel across the globe in less than a few days.
In the Western world (where food, hygiene and medical advances are keeping virtually every member of society alive), it is easier to pass bad genes to the next. The process of natural selection is no longer applies to many human civilizations. Virtually everybody's genes will make it into the next generation, not only those who are best adapted to their environments.
Humans are at the end of the evolutionary line. We are not going to see any changes, apart from ones we deliberately introduce ourselves. When we start to bio-engineer people, by introducing genes into their bodies, so they live longer or are stronger and healthier.
It just takes a while sometimes for their effects to become apparent"(Blue 2002). This expalins that if the world is about to end humans are able to mutate into something that will find a way to help them to survive and live in the world where it can be hard and competitve aduring and after the end of the world or the apocolypse. When the world will "end", medicine will be out of busniss and people do always get sick and get wounded so if people are able to evolve in to something that will help them to survive without any nurses, doctors and medication, people's chances will be able to survive will be completely high. An exampleof this will be when people will have the ability to recoperate very fast or heal fast, they will be able to survive and will be able to pass on these powers or talents to their children when they reproduce.This is when the suriviall of the fittest will come in and will be very handy.
