Human Genetics and Evolution from Within

Human Genetics and Evolution from Within

Change, change, change, one thing is for certain and that is change. Human genetics and evolution have at least one thing in common and that’s change. Everything around us is switching from what was, to what is, and from humans to the environment we are changing. Scientists have discovered how man was formed from it be a monkey or not, genetics played a huge role alongside evolution.

Humans have evolved over a thirty-five thousand years span and will continue to change and that is why it is possible, to be what we are today. We all remember the poster of the gorilla slowly evolving into a man, is that true, did humans evolve from monkeys, if so why did we stop there and why aren’t we called “momans”? But if that’s the case why do we all look so different? Well according to a study done by Pedro Simoes, in a book titled The role of Geographical Orgin and Founder Effects in Laboratory Adaptation, they state that, “In particular, differences in adaptive dynamics have been shown between populations with different ancestors that share a common environment in which they undergo subsequent adaptation” (Simones). Through human evolution depending on their place of origin humans were able to change along with their cultures and fellow people. So pretty soon one culture would differ from the next both physically and emotionally. They go on to say that, “With respect to the subsequent evolutionary rate during laboratory adaptation, starvation resistance varied considerably among foundations such that the outcome of laboratory evolution is rather unpredictable for this particular trait, even in direction” (Simones). It is interesting to understand that through time each species that couldn’t develop would die off, like the short-necked giraffes. Because most giraffes have long necks and were able to eat the leaves on the top of the trees as well as the bottom verses the short-necked giraffes only being able to eat from the bottom. When food was scarce and the long necks were eating the bottom leaves as well, the short-necks were soon extinct. So if humans had a trait that didn’t accommodate reproduction it too, would die out.

Another study done by Franz and Nunn on the “Roger Model” through the journal Of Evolution Biology they state that, “Using simulation experiments, we re-analyzed extensions of Rogers’ model after relaxing the assumption that genetic evolution is much slower than cultural evolution” (Franz and Nunn). To learn about a species it is important to see where they come from, because people in Africa may be genetically different than those from Poland. Another part of Rogers’ model states that, “For many parameter settings, genetic and cultural evolution occur on the same time scale, and feedback effects between genetic and cultural dynamics increase the net benefits” (Franz and Nunn). That is true, the more information you find through genetics, evolution and environmental dynamics the more knowledgeable you will be.

Over thirty-five thousand years ago evolution and human genetics began working together as a team and together were able to change, as did evolution. And as time continues to change human genetics and evolution will change alongside harmoniously. Change is part of life, part of evolution, without change we would probably be stuck in a monkey’s body. So, in this case I am welcoming all further changes.
