Speciation or nah?

Evolution has been occurring on earth for thousands of years and will continue to for the foreseeable future. The process of evolution is the change in a population over time to become more fit in its environment. This allows for the appearance of new species branching from its parent species this process is called speciation. Between two closely related species there are often reproductive barriers, these can take the form of pre or post zygotic barriers. If these barriers are broken down, a hybrid zone opens in the middle of the species. the fitness of the hybrids can change the course of the two parent species forever. If the hybrid is less fit the two species will continue to evolve until reproductive barriers occur or if the hybrids are more fit they could coexist or merge into a single species. the rate of speciation at a normal rate is called gradual speciation and quick transition is called punctuated equilibrium.

The whole process of evolution astounds me, but the most interesting part is definitely the way that it occurs. the minute differences between each individual in a population. Mutations can cause this change, but how often does it work out? We are worried about mutations in our DNA because it can cause cancer but is it possible the mutation code also change and start coding for something beneficial? This does happen in the wild or else we wouldn't see evolution take place at all.

For Evolution to occur it must go hand in hand with Natural Selection. This relationship allows for the death of less fit organisms and rise of organisms that are more fit. Have Humans been able to get over natural selection and therefor have stopped evolving?

In todays world most of the world has access to medicine and this is a good thing but is it possible that it is stopping our ability as a species to evolve? Having the ability to get medicine has allowed a lot of people who could have died from a certain genetic diseases to continue living. This allows them to have kids and continue passing on the same traits they had before, so the less fit are still surviving and reproducing.

Speciation can occur anywhere in any circumstance and has caused the biodiversity we see today. The study of evolution and genetic modification leads into a field i find very interesting. This knowledge can be applied to genetically modification of plants animals and ourselves. taking evolution into our own hands and being able to advance our species along with others to be capable of things never before thought to be possible. I believe this is completely justified and we should be able to take part in research to further this field. GMO's get such a bad public image but i believe there is good that can come from this and that it should be explored without being so patronized by the public.
