Presently, there is enough evidence that supports the likelihood of Darwinism being correct. Over the years Darwinism effectively explained the observations that people would ultimately accept thereby “washing out” the initial belief of Intelligent Design. After Mendel published, Darwinian biologists combined Mendelian genetics with Darwinism, after which Darwinism became more accepted. From a Bayesianist perspective, at that moment Darwin’s theory became more credible, the probability of it being correct increased. The concern regarding missing links and when fossils were found supported the idea that from our similar bone structure to the fossils we originated from a common ancestor.
He was a naturalist and during his many voyage he came to his theory of evolution. Species has a common ancestor, and as the environment changed either the species adapt or the become extinct-survival of the fittest. His theory help us to understand the biological changed where there is a struggle for existence and how it influence instinct in the animal kingdom, it also applies to human where natural selection has evolved as seen in their social behaviour, reasoning and physical characteristics (Crain,
Directional selection occurs when selection pressures favour one extreme of the trait distribution. Selection is disruptive when the average form of the trait is selected against while either extreme is unaffected (Darwin, 1859). As a branch of genetics, human genetics concerns itself with what most of us consider to be the most interesting species on earth: Homo sapiens. But our interest in human genetics does not stop at the boundaries of the species, for
Evolution, according to Darwin is a “slow and gradual, and endless” process. It also states that organisms are more prone to adapt in a specific environment and therefore reproduce and survive. What causes species to adapt and change in different environments is the theory of natural selection. This theory is supported by his small collection of fossils, observations and understating of breeding patterns. There are contradicting views to this theory which I will explore further in this essay, while analysing 5 texts.
This belief of natural selection came from Charles Darwin. Many ideas led him to believe what he believed. One of them was, James Hutton’s ideas about geological change. His theory consisted that sediments, rocks, soil, etc were made after the great flood and new species “rose” from that disaster and that it’s a cycle. Charles Lyell’s theory also shaped his thinking.
Park (2014) said it himself, “Thus, affiliation with one of the traditional subfields of anthropology should be no more than a starting point to the scholarly investigation of the nature of our species. "(p.2) In order to entirely fathom the nature of our species, we need to uncover how and why each subfield aids us in the understanding of humanity to the highest volume. According to Park (2014) evolution is defined in biology as the idea that species change over time and have a common ancestor (p.33). Evolution, to some isn’t a formidable way to prove to humans were they originated from. With years of research and scientific proof, evolution has become a more acknowledged theory throughout the scientific world.
Darwin, however, noticed similarities among the species, along with variation in species, leading him to believe that they had evolved from common ancestors. He came to believe that species evolved through a process called "natural selection," where species that adapted to meet the changing requirements of their ecosystem lived, and those that failed to adapt and reproduce
It was totally contrary to the Christian worldview. His theory states that species tend to change, plant and animal species evolved through natural selection. On the other hand, Darwin’s theory seemed controversial due to following reasons: contradiction with the law of physics; prominent scientists who supported creationism; movement of intelligent designers; new evidence found against Darwin’s theory of evolution. MAIN BODY Science and religion had strong ties in England in the 16th century. Revolution made in science field did not conflict with religion, on the contrary, scientific revolution only strengthened ties
Charles Darwin became famous for his theory of natural selection. This theory suggests that a change in heritability traits takes place in a population over time. This is due to random mutations that occur in the genome of an individual organism, and offspring can inherit these mutations. This was defined as the key to evolution, this is because random mutations arise in the genome of an individual. Until the 19th century, the prevailing view in western societies was that differences between individuals of species were uninteresting departures from their platonic ideals of created kinds.
Although the theory of evolution caused a stir on its own, what was most important to the Nature versus Nurture debate was the idea of our species changing over time. The idea of Natural Selection also contributed tot he debate. The phrase ‘Nature versus Nurture’ was coined by English Polymath, Francis Galton in his 1874 publication of English Men in Science: Their Nature and Nurture. Galton was Darwin’s cousin and he said in his biography that ‘The publication in 1859 of the Origin of Species by Charles Darwin made a marked epoch in my own mental development, as it did in that of human thought generally.’ At the point of publication Galton had been a medical student, a naturalist, anthropologist and an explorer but from 1865 onwards Galton dedicated his life to the study of Eugenics. In 1869 Galton published his own controversial work Hereditary Genius.
