The naturalists, although rooted in religious beliefs and explanations of the world, were the pioneers of evolutionary science because they began to look for explanations that were not found in religious texts. They explored the natural world. In today’s world, physical anthropologists focus on human variation in order to determine what factors into the physical and genetic variation of humans. Because the human anatomy is a large part of our biological makeup, some physical anthropologists specialize in just studying the human anatomy and physical anthropology is a good basis for other career choices s... ... middle of paper ... ...generations. If it is a beneficial mutation, then it will likely not only pass on through reproduction, but those offspring will have better odds of reproducing in order to “spread” that trait onto future offspring.

Evolution violates this fundamental premise as it cannot be directly observed or repeated. Evolutionists contend that genetic variation brought about by natural selection is observable proof for evolution. However, this is a post-hoc fallacy.
One of the earliest evolutionists was Jean Baptiste de Lamarck, who argued that the patterns of resemblance found in various creatures arose through evolutionary modifications of a common lineage. Naturalists had already established that different animals are adapted to different modes of life and environmental conditions; Lamarck believed that environmental changes evoked in individual animals direct adaptive responses that could be passed on to their offspring as inheritable traits. This generalized hypothesis of evolution by acquired characteristics was not tested scientifically during Lamarck's lifetime. A successful explanation of evolutionary processes was proposed by Charles Darwin. His most famous book, On the Origin of Species by Means of Natural Selection (1859), is a landmark in human understanding of nature.
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.
They adapt to mankind’s defences to generate more breeding grounds of MRSA in humans and animals to generate growth. Genetic variation does not have to occur randomly as plasmids can transfer segments of DNA to distantly related organisms. Any inherited, genetic change in a population which takes place over several generations is defined as Biological evolution. Darwin and Lamarck have contributed majorly to the evolutionary theory. Although Lamarck’s theory was unsupported, he probably provided inspiration to Darwin and many other enthused scientists.
Charles Darwin Charles Darwin was a naturalist and geologist, he is widely known for his evolutionary theory. “Darwin's general theory presumes the development of life from non-life and stresses a purely naturalistic (undirected) "descent with modification". That is, complex creatures evolve from more simplistic ancestors naturally over time. In a nutshell, as random genetic mutations occur within an organism's genetic code, the beneficial mutations are preserved because they aid survival -- a process known as "natural selection." These beneficial mutations are passed on to the next generation.
Evolution is defined as the process by which different kinds of living organisms are thought to have developed and diversified from earlier formed during the history of the Earth. Evolution is the reason we have so many different species. The basis of evolution comes from survival of the fittest. Those who do survive create an offspring even more fit for survival. The process of natural selection supports the idea of survival of the fittest and plays a key role in evolution.

It was not until he took his trip to the popular islands of the Galapagos did he really understand everything that was going on. He was able to fill in missing blanks that he could not decipher before. His first discovery of the Galapago archipelago was during his excursion on the Beagle that was mentioned before. They were responsible for taking five weeks to carefully chart the islands that ended up being remarkably accurate for a map in 1835.
Romanticism: The Darwinism Theory Charles Robert Darwin was an English naturalist during the 19th century. He joined a team of scientists exploring the world over five years in a ship. The naturalist contributed knowledge on the evolution of life on earth. Darwin is a remarkable figure in evolutionary history due to his Darwinism theory. Two of the fundamental facts of Darwin’s theory are: Evolution and Natural Selection.
Charles Darwin changed this though, when he studied and published his book, “The Origin of Species by Means of Natural Selection or the Preservation of Favored Races,” on his explanation of evolution through natural selection. After Darwin, many scholars followed in his footsteps to explain further theories. As technology advanced, there were more explanations for the concept of evolution followed by evidence and data because of the technology available to us. Without Darwin and technology, evolution would not be at the understanding that it is today. Charles Darwin came up with the theory of natural selection that caught the public’s attention due to its opposing ideas from other scientists of his generation.
