General purpose:         To inform.

Specific purpose:          To inform the audience on the life and contribution of Charles Darwin       in the field of science

Thesis statement:       From the theory of natural selection Charles Darwin remains one of the   most influential figures in history.

Introduction

  1. a) Attention Getter: From the theory of living thing evolving from one ancestor Charles Darwin gained fame in the science field and the society. ?
  2. Audience Connection: Charles Darwin came up with the evolution theory as an explanation for the origin of all living things, and this theory fascinated many scientists as well as raising controversies in its validity.
  3. Thesis statement: From the theory of natural selection Charles Darwin remains one of the most influential figures in history.

Body

Transition: After introducing the topic it is imperative to look at the early stages in the life of Darwin

  1. The Voyage of Beagle introduced Darwin to what would result in the evolution theory
  2. i) Darwin was in agreement with Charles Lyell ideas of uniformitarianism
  3. ii) Darwin made observations and theoretical explanations of the wild animals and fossils during the trip, which developed the main ideas of the evolution theory

Transition: After discussing the foundations of Darwin’s theory, the next step is to look at the theory itself

B.After putting together these and other ideas Darwin published the book the Origin of species

  1. i) The book gives explanations of the evolution theory
  2. ii) Additionally, the book came up with the idea of natural selection to further support the case for evolution.

Transition: After I have discussed both the origin and the theory, it is necessary to look into the response of the theory as well as other works by Darwin.

C The reception of the book as well as other publications of Darwin are also beneficial in determining his contribution

  1. i) The idea of evolution sparked Controversies and debate among some individuals who did not find the idea comfortable
  2. ii) Apart from the origin of man Darwin made other publications that impacted on the scientific field

Conclusion

Main points

  1. Voyage of Beagle
  2. 2. Origin of species
  3. Reception and other publications

In conclusion, it is noteworthy that Charles Darwin made an impact in the scientific field of and was a historical figure that made significant contributions.

Speech

Charles Darwin an English naturalist gained fame in his generation as well as afterwards his death. Darwin was born on February 2 in 1809 and died in April 19 1882. His fame arises from his development of the evolutionary theory. Most of his evolutionary theory informs in his book Origin of species first published in 1859. The evolutionary theory advanced by Darwin was that all forms of life descended from a common ancestor (Holder 2004). He proposed that the process of evolution resulted from natural selection where the struggle for existence and had a branching pattern. The evolution theory stems from the work of Charles Darwin and formulates a uniting theory of the life sciences.

Darwin’s interest in nature steered him to abandon his medical career, started to investigate invertebrates, and assisted Robert Edmund Grant. The Voyage of Beagle was Darwin’s first significant expedition in which most of the subsequent work develops. The expedition surveyed and charted the coasts during the expedition and made observations and theoretical speculations throughout the expedition. This expedition established him as a distinguished geologist, and his observations and theories reinforced the uniformitarian ideas of Charles Lyell. He was puzzled by the distribution of wildlife fossils, and he investigated the transmutation of animals to come up with the theory of natural selection (Darwin 2010).

The most noteworthy of Darwin’s publication is the Origin of species, which detailed the evolution theory, which Darwin is better known for. In this book, Darwin gave a logical and detailed explanation behind the theory of evolution. The book was widely popular but attracted controversies on the issue of evolution. Although this book initially attracted controversies, scientists came to accept the theory. In this book, Darwin spoke of shared descent and not on evolution to avoid controversies, but the issue was strongly debated from the moment the book was released.

Holder (2004) provides that Darwin’s other works include evolution by natural selection and common descent. He was also an excellent writer and apart from the origin of species, he published other books including the descent of man, the expression of emotions in man and animals, the power of movement in plants and animals and the formation of vegetable mold through the action of worms. Darwin also made other significant publications that were both published an unpublished.

Darwin’s health suffered because of his overwork and was frequently incapacitated by stomach pains, vomiting, palpitations, and trembling. Darwin married his cousin Emma Wedgewood after deliberations on marriage jotted down in his notes in a style of pros and cons. Darwin died of heart failure in 1882, and his last words were an encouragement to his family. Upon his death, Darwin was buried close to Isaac Newton and John Herschel in Westminster Abbey. He was one of only five 19th-century non-royal public figures honored with a state funeral.

Darwin was able to convince many scientists of his evolution theory and his work has had an extensive influence in the field. The importance of his theory is that it explains the origin of man. This theory was later validated by scientists and identifies Darwin as a distinguished scientist. Darwin’s work has been celebrated by numerous event and publications and several other things named after him including animal species and natural features (Bowler 1996).
