Humans take Control of Evolution
Humans have only existed about 130, 000 years ago and we have recently evolved. Human activities are driving the evolution of other species in dramatic and often unexpected ways. Natural selection no longer affects us but we have effect it in many ways. Another way, we control the outcome of our race is "self-designed evolution” (Hawkings, 2009).

Unnatural Selection takes part of our control of evolution. For example, the geographic isolation of different groups has been broached. “Never before human gene pool has been widespread mixing of what were heretofore entirely separated local populations of our species.”(Ward 2009). Our genes have been mixing by interbreeding. Today we have now created the world Utopia. Steve Jones of University College London said “Utopia if you want to know what Utopia is, just look around you.”(Jones 2002). In today’s society almost everyone has the opportunity of equal chance to having children. Homo sapiens is one of the largest living species in the world and we can change or help the way we live easier.

Stephen Hawkings is a British theoretical physicist, cosmologist, and author. He created a theory called Self Designed Evolution, it is a new phase of evolution we are entering. He said that we will be able to change and improve our DNA. "These changes will be confined to the repair of genetic defects, like cystic fibrosis, and muscular dystrophy. These are controlled by single genes, and so are fairly easy to identify, and correct.” (Hawkings, 2009). It will be good and helpful for our survival if we can alter and improve our DNA and fix the problems some people may suffer from. He also said that in the next century, “people will discover how to modify intelligence and instincts like aggression.”(Hawkings 2009). This is dramatically change are way of thought and survival and will impact the Earth and its surrounding environments. We...
