Charles Darwin is well known for his groundbreaking work in evolutionary biology. Among his many contributions, The Origin of Species is the most associated with his name. It introduces the scientific theory of evolution and suggests that species evolved over a period of generations through a process called natural selection. Darwin's theories caused much controversy among his colleagues and gave rise to much debate. However, the massive amount of criticism directed at Darwin convinced him to make revisions. As a result, his future editions will differ significantly from previous versions and he will also address some of the problems people have had with his theory in later versions. Unfortunately, his adjustments had somewhat obscured his original argument, making his first edition the best representation of Darwin's ideas. Charles Darwin begins The Origin of Species by explaining his theory of natural selection. He claims that animal and plant breeders had a profound impact on the changes they created among domesticated species. Darwin used the common practice of animal breeding as a means of introducing artificial selection in order to help readers in 1859 understand the possibility that nature was also capable of producing similar changes through the same process of selection. Darwin believed that his theory of variation and heredity played a vital role in human reproduction. However, these kinds of ideas were treated as absurd because there was no direct evidence supporting the belief in genetics at the time. The idea was that people were made up of genetic variables and that each gene would be passed on as a unit to the next generation. As a result, Darwin argued in the middle of the article......aware that the fossil record contradicted him because it represented the fact that new species had arisen without any evidence of evolutionary ancestry. Darwin argued that the fossil record was not accurate and should not be used as an indication of whether species are suddenly introduced. He also claimed that rocks containing fossils are only created in special situations and after a long period of time since their creation. Another problem with fossils arose after the sudden discovery of an entire group of living things at a certain time in the fossil record. The best example of this was the discovery of all the basic modern types from the Cambrian era. Darwin is trying to argue that the imperfections in the record include these fossils. Even though he had many hypotheses about it, he had no evidence to support it..
