Charles Darwin s Theory Of Evolution - 1279 Words

Charles Darwin’s theory of evolution, also referred to as Darwin’s Theory, is a widely held notion that organisms descended from a common ancestor; which he developed after the time of his extensive research on the Galapagos Islands. The publication of his work in 1859, The Origins of Species, along with other scientist’s discoveries relating to the topic, laid the groundwork for the understanding of the origins and evolution of life itself. Darwin’s contributions to the theory were supported by his observations of finches and tortoise on the islands, claiming that there are slight physical variations among species according to their adaptations to their own environment. Furthermore, he was able to hypothesize about why and how evolution†¦show more content†¦According to Esteban J. Parra in his article on, Human Pigmentation Variation, he states that, â€Å"The average proportion of genetic variation due to differences among major continental gro ups is just 10–15% of the total genetic variation.† However, the article focuses its attention on the distribution of skin pigmentation and how it differs geographically among continental populations. The reason for the international variation across human populations is heavily influenced via natural selection. Melanin and UVR levels in relation to latitude are key components that are responsible for the variation in skin pigmentation. There is strong correlation between skin pigmentation and latitude, showing, â€Å"Geographic patterns of skin pigmentation in human populations.† Those who are located closer to the equator and tropical areas tend to have darker skin, oppose to those who live in colder regions that have lighter skin. Melanin acts as a natural sunblock underlying the skin that helps protect from harmful UV radiation exposure from the sun. The evolution of skin pigmentation is a result of geographic location and the level of exposure of UV radiation. Since our species first evolved in much warmer climates, they had adapted to their environment by inheriting the advantageous trait of darker skin to protect from the sun. Those who obtained lighter skin pigmentation in those areas would be prone to sunburn and susceptible to a number of skin cancers.Show MoreRelatedCharles Darwin s Theory Of Evolution984 Words   |  4 PagesCharles Robert Darwin was a British man who became one of the greatest contributors to the study of evolution. He was a naturalist who was able to develop a theory of evolution based on biological changes that he witnessed occurring in varieties of samples on his travels all around the world.

Charles Darwin’s theory on evolution, which is called natural selection, is based on the idea of species naturally adapting to their surrounding environment to better the species chances for survival. Creationism, on the other hand, is the belief that the universe and living organisms originate from specific acts of divine creation. Both are theories on life, and how such life came to be thing we all know.

Questions abound. Is evolution a four billion year old process, creating life forms primarily at random but each shaped by an ever-changing and complex environment, that has resulted in all of the wondrous life forms that surround us? Or are all of those beautiful elements of our nature, along with the vastness and majesty of the entire universe, a creation of an intellect of vast intelligence andRead MoreCharles Darwin s Theory Of Evolution1055 Words   |  5 Pages Charles Darwin was an English naturalist and geologist, he was known greater for his contributions for the evolution theory.
