Evolution And Charles Darwin´S Natural Selection

830 words - 4 pages

Evolution is a very hot topic, causing lots of controversy for almost 200 years. It is the belief that creatures have changed and adapted to their environments over time, and that the Earth is more than 6,000 years old. It is shown to be true using radiometric dating, showing some things to be millions of years old. Another theory contributing to some of this is the theory uniformitarianism. This shows rock layers that are more than 6,000 years old, built on top of each other, showing a timeline of rock.

Evolution was understood in layers by various scientists over the years. Some got small pieces of it in their earlier writings, but it was not truly put together until Charles ...view middle of the document...

In fact, Darwin's first book is dedicated to Charles Lyell, a predecessor of Darwin in the world of evolutionary theory. This shows that scientists build off each other to get these theories, such as Darwin incorporating parts of Charles Lyell's theory of uniformitarianism in his research. He showed that fossils of amphibious organisms can be found in the Andes mountains. This shows that the Andes Mountains used to be underwater.
Another key point of Evolution is the thought of where we, humans, come from. One of the leading theories is Darwin's, which says that we evolved from Primates of some sort. Humans are classified into the category of Homonids, which is part of the primate family(Nowicki). This is a direct statement as to the fact of where we came from, or at least, science's theory about it.

Darwin's theory of natural selection is a very big part of evolution, showing the gradual adaptation of characteristics in species. Natural selection is the gift of new beneficial adaptations to animals of a species, for the purpose of survival. The good traits are kept through the survival and reproduction of animals with the traits. The bad traits will be eliminated along with their carriers, and weeded out of the gene pool. New traits can be made from mutations in the DNA of the offspring.

Better traits can be given out more plentifully using overproduction, where the bad traits will die out, and the strong ones will live....

Natural selection, Charles Darwin Essay

716 words - 3 pages The most important experience of Darwin's life was his trip aboard HMS Beagle as a naturalist. The Beagle left England in 1831, and it returned in 1836. The overall purpose of the voyage was to map uncharted areas of the South American coastline. And then, he wrote the theory of Natural Selection:         One of the prime motives for all species is to reproduce and survive, passing on the genetic information of the species from generation

Charles Darwin and Evolution Essay

1139 words - 5 pages The theory of evolution, as set forth by Charles Darwin in 1859, stated that all plant and animal life evolved over long periods of time from simple to more complicated forms through mutation and adaption. He also taught that only the fittest on each species would survive. This concept is called "Evolution by Natural Selection". Natural selection is that the strongest survive and propagate and therefore increase in the strength of the species.On

Beginning with the pioneeringwork of Charles Darwin, evolutionary biologists have been fascinated with how heterostyly hasevolved and how it functions in plant populations.The polymorphism has evolved independently in approximately 25 Angiosperm families.A final example of natural selection involves the evolution of long floral tubes in mothpollinatedflowers. Work by the Swedish pollination biologist L. Anders Nilsson has resolved a long-standing controversy concerning the pollination biology of rare Madagascan Orchids with extremely long floral tubes.

Charles Darwin's Theory of Evolution by Natural Selection

787 words - 3 pages Charles Darwin's theory of evolution centres on the idea that species compete to survive, and favorable characteristics are passed on from one generation to the next. Darwin said that evolution took place by a process of natural selection or survival of the fittest. This meant that the animals and plants best suited to their surroundings survived and were able to pass on their genes to their offspring. The ones that
