The Future of Evolution
One could argue that our species does everything it can do secure a future for ourselves and our future generations. We have traveled to the stars and back, we explore every inch of our land and travel to the deepest depths of our oceans, and we probe the earth for any resources we can find, all in order to find the best possible option for the human species to survive. But are we really doing the right thing for our species to survive?
Evolution is the theory that all living forms came from ancient ancestors and is the natural process to improve a species chance of survival. Through a series of mutations, genetic drift, migration, and natural selection today’s descendants show an amazing amount of similarities and diversity. Evolution on a small scale is called microevolution, an example being the

The transition started with apes beginning to stand up straight and on two feet rather and four, then they began to have larger and more complex brains, which then lead to apes learning to communicate through sounds and art, until finally the apes “evolved” into who human are today and began making tools and forming communities like we have today. Many scientists believe that this will continue and eventually we will adapt and become a “new” species; However, I believe over the past 6000 years when civilization began, was the moment we started to pull ourselves out of evolution and cheat “survival of the fittest”. From our creation of large cities to the invention of the machine gun and nuclear warheads, our society is not threatened by anything except ourselves; therefore, we are not evolving to further better our chances of survival. I have found few example of how our species is no longer affected by survival of the fittests. First,
What is evolution? Evolution in modern terms is fairly easy to understand. Evolution is the theory that life on earth began with a single celled organism that lived more that 3.5 billion years ago that slowly evolved into many diverse creatures over time. When you break down this theory into sections you get 6 factors: evolution, gradualism, speciation, common ancestry, natural selection and nonselective mechanisms of evolutionary change.
What is evolution? Evolution is the process at which all living things that are around use today that have ancient ancestors in their background. Also, with evolution it allows for use to see how we have similarities as well as differences from all living organisms from the past to the present. By being able to see the similarities as well as differences it shows how overtime we have changed and evolved through the use of evolution. However, the use of evolution involves different mechanisms in order for it to take place.
Evolution is the theory that all living organisms can be traced back to a common ancestor, which came into being from non-living elements, by natural laws. Darwin’s contribution to this theory was the mechanism by which species could evolve – natural selection.
The process of evolution, as discussed by numerous scientists as a well-accepted phenomena in which species adapt to their environment over numerous generations, has become a scientific cornerstone on which several scientific theories concerning the species of the Earth and how they arrived where they are now are grounded in. One of the most predominant species of the Earth being us, the human race. Did the human race evolve over great expanses of time from more primitive beings? In what ways can science explain how humans got to where they are today? Did mankind evolve from a single area on Earth?
In order for a species to survive, its population has to evolve. Evolution is the process of gradual change driven by natural selection to improve survival. Evolution is the explanation of how life got to its current state. Before the idea of evolution, the Bible gave the explanation of how things came to be, the Theory of Creation. Charles Darwin is credited for developing the theory of evolution.
Darwin stated that humans will continually evolve the older our species gets. This means until something changes enough to make us go extinct than
“The scientific study of how humans developed did not begin until the 1800s in Europe. Until that time, people relied on religious explanations of how humans came into existence. Starting in the 1500s a scientific revolution began to sweep Europe. Thinkers started using scientific methods and experiments to try to better understand the world and the creatures living in it. Eventually these methods were turned to the question of human origins” (The Nature Of Human Origins, 1). Earth made it possible for species to change over time because Ancient Earth provides ability to plenty of time.The Homo Sapien a is very complex creature. The species started off very simple by living in caves and surviving with little food and then later evolved into a species that were able to do many more complex things. The first species was Sahelanthropus tchadensis They were one of the most simple humans in that time period and on. They had very small skulls compared to Homo Sapiens today and their motor skills were just the same. We have evolved and changed for the better both mentally and physically. The Evolution of Homo Sapiens started off simple, such as the Neanderthals, and now we are the most advanced species to ever walk the planet so far.
The thought of evolution is filled with theories, ideas and beliefs. The definition of evolution is rather simple. According to Jerry A. Coyle, evolution is “the change in the inherited characteristics of biological populations over successive generations (2). Evolution gives rise to diversity when it comes to the hierarchy of life otherwise known as biological organization. Many people find the topic of evolution to be troubling and very confusing. Throughout history churches have preached that evolution is atheistic and a sin if even thought about. Famous scientist, Charles Darwin, is said to really be the first to formulate debated theory of evolution by the means of natural selection. Eventually in the 20th century genetics was compounded with Charles Darwin’s theories of evolution. Even today scientists continue to study different aspects of the theory of evolution.
Are we still evolving? How do humans and apes share a common ancestor? Modern human species or Homo sapiens have shown great similarities in the physical and genetic makeup to another group primates species, the apes. Both organisms share a common ancestor dating back eight to six million years ago. Evolution means change over time. Human evolution is the process by which humans have emerged from apelike ancestors. Through sequences of mutations, genetic drift, migration, and natural selection and technology we are able to observe the amazing amount of similarities and diversity of humans to other living organisms. Humans have roamed the earth for about six million years. At least, that is from when the oldest human ancestor was discovered.
We live in a world where the strongest and most adapted survive which is called natural selection, which is also vital to my next argument on why I disagree with
The evolutionary theory is the concept that species evolve over time through the mechanism of natural selection of survival and reproduction. Natural selection means acting on the assumption that various living organisms were produced by genetic diversity and mutation. The evolution theory may also be referred to as the philosophizing science. This theory states that all phenomena are derived from natural causes and can be explained by scientific laws without reference to a plan or purpose.
What is evolution and how does it work? Evolution is the theory of how one form of life changes into another form. Evolution also is the change of a population’s inherited traits from generation to generation. Evolution helps to explain why an animal, human, and plant looks the way it does and acts the way it does; it gives an explanation of the history of life. Genes come in many varieties and the evolution helps to make it happen. Mutation, natural selection, genetic drift, and gene flow: the four forces that make the evolution work.
Evolution is the complexity of processes by which living organisms established on earth and have been expanded and modified through theorized changes in form and function. Human evolution is the biological and cultural development of the species Homo sapiens sapiens, or human beings. Humans evolved from apes because of their similarities. This can be shown in the evidence that humans had a decrease in the size of the face and teeth that evolved. Early humans are classified in ten different types of families.
Are humans still evolving? As society develops, humans are not only satisfied with the ability which gave from technology, but also looking forward to get more power from themselves. When people focus on analyzing the methods to improve human ability, they found out an important source of it, which is human evolving. Evolution is a process of developing over successive generations as a result of natural selection ("Evolve" 1).
Without evolution, and the constant ever changing environment, the complexity of living organisms would not be as it is. Evolution is defined as a process that results in heritable changes in a population spread over many generations (8).Scientists believe in the theory of evolution. This belief is based on scientific evidence that corroborates the theory of evolution. In Figure 1 the pictures of the skulls depict the sequence of the evolution of Homo-sapiens. As the figure shows, man has evolved from our common ancestor that is shared by homo-sapiens. The change of diet of homo-sapiens over time has thought to contribute to the change in jaw structure and overall skull shape.
