Charles Darwin s Theory Of Inheritance Of Acquired...

Evolution has been a very debatable topic since the theory of evolution first evolved. By definition, evolution is â€Å"the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth†, but there are many different types of â€Å"evolution† such as coevolution, divergent, parallel and convergent – all with different theories. Jean Baptiste Lamarck was a French naturalist who invented the theory of inheritance of acquired characteristics (aka. â€Å"soft inheritance†). This evolutionary theory described how the natural environment affected the way an animal used their body parts. The features used regularly or for survival are passed onto the creatures offspring, and the parts that weren’t used, weren’t. On the other hand, another English naturalist Charles Darwin established a theory of â€Å"natural selection†. A process in which creatures that survived in thei r environment would pass their genes through the generations, compared to the weaker species with a lower survival rate, who reproduce less offspring or none. An adaptation is a result of evolution. They can be structural (physical features), behavioural and physiological (special response e.g. snake producing venom). These adapted characteristics (or mutations) develop for a creature to survive in it’s environment better, which are then passed on to its offspring. For example, the Wolly Mammoth possessed a number of physical adaptations to survive the coldShow MoreRelatedJean Baptiste Lamarck And Charles Darwin s Theory Of Inheritance Of Acquired Characteristics926 Words   |  4 PagesBackground information: Jean-Baptiste Lamarck and Charles Darwin both thought and had ideas on how life on Earth got to be the way it is now. Unlike lots other people at that time (1800’s), they both thought that life had changed gradually over many years and an extended time and was still changing, that living things change to be better suited and adapted to their environments. Lamarck is best known for his Theory of Inheritance of Acquired Characteristics. He said that change is made by what the organismsRead MoreEvolution And Evolution Of Evolution1333 Words   |  6 PagesWhat is Evolution? Evolution is the modification of characteristics of living organisms over generations (StrangeScience.net, 2015); it is the gradual process of development by which the present diversity of living organisms arose from the earliest forms of life, which is believed to have been ongoing for at least the past 3000 million years (Hine, 2004).

Evolution shows how everything on earth shares a common ancestor. If Darwin and Lamarck came up with this whole evolution theory, one had to be more accurate if they both had sort of the same theories of what was happening. There have been many theories of evolution and how it is brought about and what it is exactly. Charles Darwin a scientist who came up with his theory of evolution and how it works.

Evolution by natural selection is a very important concept in biology since it lays the foundation of evolutionary thought of how organisms have developed gradually over a long period of time. The ideas of evolution were not accepted until Charles Darwin published his book â€Å"On the Origins of Species by Means of Natural Selection† in 1859. Before the evolutionary thought, people believed that all organisms were created at the same time and that each life-form was fixed and therefore did not changeRead MoreThe Theory Of Evolution By Natural Selection1329 Words   |  6 PagesThe theory of evolution by natural selection proposes that all species are related (Eade, S. and profile, V. 2014). 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 MoreThe Theory Of Evolution By Natural Selection1027 Words   |  5 PagesPart 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.

Charles Darwin put forth a coherent theory of evolution and amassed a great body of evidence in support of this theory. In Darwin s time, most scientists fully believed that each organism and each adaptation was the work of the creator.

These theories began around Charles Darwin’s time, â€Å"No one knew how old the earth was, but geologists were beginning to make estimates that the earth was considerably older than explained by biblical creation. Geologists were learning more about strata, or layers formed by successive periods of the deposition of sediments. This suggested a time sequence, with younger strata overlying older strata.

Evolution was a controversial topic because it went against the Bible. However, the first scientist to publicly state his ideas about evolution was Jean-Baptiste Chevalier de Lamarck. He thought that evolution was due to inheritance of acquired chara cteristics as organisms adapted to their surroundings. Meaning that when an organism would use a body depending on how it was used would pass on to its offspring.
