The topic of this paper is what does the future have in store for the evolution of Homo Sapiens. Of course, human beings will continue to change culturally; therefore cultural evolution will always continue; but what of physiological evolution? The cultural evolution of man will continue as long as man can think; after all it's the ideas we think up that makes up our cultures. In a thousand years man might complete a 180 degree turn culturally (not to mention physiologically) and as seen by our fellow inhabitants of earth we would in essence be different beings. One can say that this new culture has chosen its ideas based on Natural Selection.
(C.Darwin, 1859) Two notable scientists associated with the theory of evolution include Charles Darwin and Jean-Baptiste Lamarck. Charles Darwin contributed majorly to the evolutionary theory and was the first to consider the concept of natural selection. The evolutionary theory states that evolutionary change comes through the production of genetic variation in each generation and survival of individuals with different combinations of these characters. Individuals with characteristics which increase their probability of survival will have more opportunities to reproduce and their offspring will also benefit from the heritable, advantageous characteristic. So over time these variants will spread through the population.
The three effects are bad, neutral, and good. Having a bad mutation can cause one to have a harder time being able to survive. Having a neutral mutation will not change or help one to survive. Having a good mutation will help one to survive and have a better chance of survival. However, mutation is random in the evolution, and provides raw material for natural selection, genetic drift, and gene flow... ... middle of paper ... ...he genetic differences making more of a variation but it does this process slowly.
A third contention of Darwin's theory of evolution is that species change gradually over time by a process of inheriting very small differences. The mechanism for evolution, according to Darwin, is a process known as natural selection. Natural selection is based on the principle that occasionally an organism will develop a mutation that will increase its chances for survival. The progeny of this organism will inherit this advantage and will eventually become prevalent among the population as a result of this advantage. This will lead to a change in the gene pool of the species.
The forces of natural selection on the evolutionary processes in humans can have a broad range of effects on the characteristics of humans. There are no concrete answers to some of the questions proposed in this paper, but time will soon tell exactly how the evolutionary mechanisms have effected the human race. The human species will continue to evolve as long as the mechanisms of evolution and environmental factors act upon us.
The process of natural selection supports the idea of survival of the fittest and plays a key role in evolution. For species to evolve, there must be diversity present. When diversity is acted upon, a mutation happens. Mutations are alterations that happen in the genes, or the result of genes not being able to copy themselves properly. At first, mutations may seem almost non-existent to the eye, but over time the mutation will become more visible.
One of the most important principles of biology is the main idea of evolution. This theory states, “that all living organisms have evolved from a common ancestor through natural selection acting on hereditary variation” (Reece, 2011). Many people today, know humans have evolved from a common ancestor; but they do not recognize the importance of it. Everyone should be educated about how organisms evolved because humans have evolved throughout many centuries. Charles Darwin had many theories that incorporated the main principle of biology, natural selection and evolution.
Charles Darwin in his book, On the Origin of Species, presents us with a theory of natural selection. This theory is his attempt at an explanation on how the world and its' species came to be the way that we know them now. Darwin writes on how through a process of millions of years, through the effects of man and the effects of nature, species have had an ongoing trial and error experiment. It is through these trials that the natural world has developed beneficial anomalies that at times seem too great to be the work of chance. Darwin writes on how a species will adapt to its environment given enough time.
I became interested in this topic because it hard for me to think at one time humans had tails, or that some species of ape’s DNA is very similar to ours. Darwin 's theory of evolution states that all life is related in one way or another. He explains this by saying that due to random gene mutations form more advanced organisms from their simplistic counterpart. This feeds into the second half of his theory. This part of the theory is natural selection, or survival of the fittest.
This era of early tool development took place during the Lower Paleolithic, and was known as Oldowan tool tradition. Anthropologists suspect that a feedback loop between brain size, behavior, and language began to develop during the time of Homo habilis, due to a proposed correlation between the gradual increase in brain complexity and size as well as the development of more complex cultural aspects of their society, such as the various tools developed during the era of the species habilis. The arrival of Homo erectus, about 2 million years ago, marked another noteworthy progression of biological and cultural adaption, as well as further evidence supporting the feedback loop
