Trends in Evolution Background 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 organisms want or need. For example, Lamarck believed that giraffes stretched their necks to reach food. Their descendants and later generations inherited the resulting long necks. Lamarck also believed that evolution happens according to a prearranged plan and that the results have already been decided. (NECSI, 2012). Darwin, on the other hand said that organisms are all different and that those which happen to have variations that help them to survive in their environments survive and have more offspring. The offspring are born with their parents helpful traits, and as they reproduce, individuals with that trait make up more of the population. Other individuals, that are not so well altered, die off. Darwin also believed that evolution does not happen according to any sort of plan. We now know that there are four basic parts by which biological evolution takes place. These include mutation, migration, genetic drift, and natural selection. Each of theseShow MoreRelatedThe 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 MoreEvolution And Evolution Of Evolution1110 Words   |  5 Pagesmore to it. 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 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). Common ancestry are groups of living organisms that share the most recent common ancestor, by which scientific evidence proves that all life onRead 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.

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 MoreA Note On Evolution And Evolution1425 Words   |  6 Pagescontributions to the theory of evolution. 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 characteristics 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. Nonetheless, his theories were wrong thoughRead MoreEvolution ; Procoptodon à ¢Ã‚†Â’ Red Kangaroo1820 Words   |  8 Pagesgenetic inheritance. Biological evolution itself is the change in characteristics of living organisms over generations. Evolutionary theories suggest that all organisms alive today share a common ancestor. As unlikely as it sounds, evidence has been discovered proving this theory (relations from a spider to a monkey). A more simplistic way of thinking of evolution is â€Å"descent with modification† which is essentially stating, over many generations, organisms change.

The method of how science was conducted drastically altered as well.

In some places, the text describes a narrative or story of events that led to Darwin’s theory of evolution.

Exactly how evolution occurs is still a matter of debate, but there are many different theories and that it occurs is a scientific fact. Biologists agree that all living things come through a long history of changes shaped by physical and chemical processes that are still taking place. It is possible that all organisms can be traced back to
