Lamarcks Influence Upon Charles Darwins Theory of...

There have been many ideas on the theory of evolution. Some simply take our existence for granted, others prefer to explain all evolution in terms of the bible and the presence of a God. However, there are those who have researched the topic of evolution and have offered an explanation as to where a species comes from and how they evolved in the manner that they did. This type of science has been studied for a very long time, and one of the most famous minds in the field of evolution was a man named Charles Darwin. Darwin was not the first one to offer theories on evolution. There have been many scientists who preceded him. These earlier evolutionists came up with models of evolution that were unfortunately unworkable. One of†¦show more content†¦(Gould, 1980) Darwin did not deny any of this. He regarded it as support for natural selection as an evolutionary mechanism. Darwins theory was more complex then Lamarcks, but the basic structure was there. Darwin had rooted his the ory on the concept of adaptation, just as Lamarck had previously done. Adaptation is the notion of organisms responding to a changing environments by evolving either a form or function of the body that would better suite it in the environment. Lamarck had explained that the method of transfer of information was directly to the organism, the animal would perceive the change and simply respond in the necessary way so that their offspring can be better adapted. Darwins answer to what the mechanism is was much different. Darwin spoke of there being two components, variation and direction.(Gould, 1980) Darwin had taken into account that the species did indeed create offspring that were better suited for the environment, just as Lamarck had said. Darwin proposed that instead of direct transfer of environmental change, those that vary by good fortune are better suited for the environment and leave more surviving offspring. A species would have this beneficial trait through random variation. Then, the characteristic would help the animal survive, while the others died off. This ensured that the beneficial trait would get passed on. This explanation is similar to Lamarkism, with obvious adjustments.

One of the biggest is that he called the theory by that name. Albrecht von Haller used the word evolution in 1744 to mean to unroll, so the word was around in Darwins time, but Darwin never used it in the sense we use it today. It was added later by others, including Herbert Spencer, who is responsible for the theory we call Social Darwinism. This theory is misnamed; it is not based on Darwins work, but Spencers.

He died on April 19, 1882 in Kent, England (Biography.com Editors). Charles Darwin brought many revolutionary visions to the world of science, including evolution. Charles Darwin was an English naturalist and geologist. He is best known for his theory of evolution, and natural selection.

There maybe several reasons for such dismissal. Within the STEAM subjects, especially science and mathematics, the content strives to be empirical and concrete without influence of culture, race, gender or era in time.

He was born in a merchant town of Shrewsbury, England. He was the second youngest of his six siblings. Darwin’s mother, Susanna, died when he was only 8 years old. He attended the University of Edinburgh Medical School (at the time the best medical school in the UK) with his brother Erasmus in October 1825. Darwin found lectures dull and surgery stressful, so he neglected his studies.

Why are his personal beliefs important when dealing with a matter of science that Darwin researched? Darwin excluded the question of a Creator from his works because it was irrelevant to his scientific research, and the debate regarding Darwin’s faith arises due to his conflicting accounts of his personal faith as well as the way his early childhood and teenageRead MoreTransforming Species Into Molecular Biology3591 Words   |  15 Pages Transforming Species into Molecular Biology Between 1850 and 1950, the definition of what science was and what it could become radically changed through means of breakthrough theories, ideas and experimentations from scientists exploring the realms outside of the traditional religious views. The method of how science was conducted drastically altered as well. The development of new technologies allowed scientists to step away from simple observation, towards more sophisticated and complex researchRead MoreOn the Origin of Species1846 Words   |  8 Pages1859, Charles Darwin clearly explained the gradual progression toward the speciation of organisms with his five main principles: variation, inheritance, competition, selection, and propagation. Darwin hesitated to publish his findings because he understood that his findings were based on the animal kingdom and on an evolutionary process that had to have spanned millennia. He specifically did not think that his discoveries were applicable to the evolution of human society. Con trary to Darwin’s preferenceRead MoreWhy Teaching Intellingent Design and Creationism in Schools and not just Evolution Isnt a Good Idea1887 Words   |  8 Pagesthe valid truth of the Theory of Evolution. As many people already are aware, there are many disagreements as to why evolution is not true and should not be taught to students in our schools. Most of these arguments stem from nothing but pure ignorance on the part of the person arguing for intelligent design to be taught in the school. They make arguments that the theory of evolution is full of holes, and that science teachers don’t reveal the disputation between evolution and intelligent design
