The Theory Of Evolution By Natural Selection - 1027 Words

Part A: Evolution of Polar Bears Introduction The theory of evolution by natural selection (Darwinism), first formulated in Darwin s book On the Origin of Species in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioural traits. Changes that allow an organism to better adapt to its environment will help it survive and that have more offspring. The first three ideas were already under discussion among earlier and contemporaneous naturalists working on the â€Å"species problem† as Darwin began his research. Darwin’s first contributions were the mechanism of natural selection and numerous amounts of evidence for evolutionary change from many sources. He also provided thoughtful explanations of the consequences of evolution for our understanding of the history of life and modern biological diversity. ïÆ'Ëœ Species (populations of interbreeding organisms) change over time and space. The representatives of species living today differ from those that lived in the recent past, and populations in different geographic regions today differ slightly in form or behaviour (Evolution Berkeley) ïÆ'Ëœ All organisms share common ancestors with other organisms. Over time, populations may divide into different species, which share a common ancestral population. Far enough back in time, any pair of organisms shares a common ancestor. (Evolution Berkeley) ïÆ'Ëœ Evolutionary change is gradual and slow in Darwin’s view.

There is estimated to be between 6 million and 100 million different species in the world, with more species undiscovered than those discovered; this is all owing to the concept of evolution (Borenstein, S. 2014). Evolution is defined as the â€Å"change in the characteristics of a species over many generations (Linstead, 2012).† The most widely accepted theory of evolution is natural selectionRead MoreNatural Selection And The Theory Of Evolution1536 Words   |  7 PagesNatural selection and The Theory of Evolution were just two of the things that Charles Darwin conquered through the exploration of The Galapagos Island. Darwin was born on February 12, 1809, in Shrewsbury, England. While Darwin was still in high school, his main interest was nature, he was especially interested in beetles. Darwin’s father, Robert Darwin, who was best known as the father of the naturalist Charles Darwin, wanted Charles to become a doctor.

Many people have always been interested in their origins and have found explanations using evidence that validates the story, but where is the proof? In 1859 a man by the name of Charles Darwin wrote a novel called the Origin of Species basically expressing the theory of evolution by natural selection. An extremely complicated story, but a very effective explanation of life as weRead MoreThe Theory Of Evolution By Natural Selection1726 Wo rds   |  7 PagesDiscussing Darwinian and Modern Evidence in Support to The Theory of Evolution by Natural selection Evolution is the gradual development of life on Earth. It is responsible for the unusual carnivorous plants (species such as Dionaea muscipula), the beautiful coloured plume of the male peacock, even the possibility of cells adapting to protect against continual low exposure to radiation (Russo, GL. et al 2012).

According to history, Charles Darwin is the first scientist to frame the theory of evolution by natural selection. It was publish in his book title On the Origin of Species 1859†. Darwin express the theory of evolution by natural selection as a process by which species change over a period of time. This change take place because of the changes in genetic and behavioral traits. The ability of the organisms to change over time or adjust to fit environmentalRead MoreThe Theory Of Evolution By Natural Selection926 Words   |  4 Pages Charles Darwin was the creator of Darwinism which is, â€Å"the theory of evolution by natural selection† (Junker 1). In school we are often taught that natural selection is survival of the fittest or the strongest wins. What seems to be a simple topic is actually one of the leading theories on the side of evolution in the highly controversial debate on Darwinism vs. Creationism. Darwinism states that certain genes in a population change thro ugh individuals. These â€Å"strong† genes are then produced moreRead MoreThe Theory Of Evolution By Natural Selection1692 Words   |  7 PagesDarwinian Theory of Evolution by Natural Selection Background information Even though evolution is an ancient concept, Charles Darwin brought up a new idea focusing on naturalistic modification of a population over time. He believed that species differ over time and space.

Darwinism rejects all supernatural phenomena and causations. The theory of evolution by natural selection explains the adaptedness and diversity of the world solely materialistically. It no longer requires God as the creator or designer .Darwin pointed out that creation, as described in the bible and the origin accounts of other cultures, was contradicted by almost any aspect of the natural world.

Evolutionary theory was developed by Charles Darwin and documented in his book ‘On the Origin of Species’ (1859). In it’s most simplistic terms it explains how and why animals, including humans, have changed and evolved over time to become the way they are. One of his more well known and supported theories illustrated in his book is the theory of evolution by natural
