that they became very different species. This is what adaptive radiation is. Charles Darwin observed this first hand on the Galapagos Islands. When Darwin first arrived on the Galapagos Islands‚ he discovered finches that looked astonishingly similar to the finches that found in South America’s islands. However‚ these finches were different in size‚ diet‚ and habitat preferences. After years of studying‚ Darwin figured that these finches on these islands all had a common ancestor that came from the

OUTLINE Introduction. Brief history on scientific theories that focused on evolution before the discovery of natural selection by Charles Darwin. Description of how the discovery was made by Darwin. Key points of evolution by natural selection. Conclusion. Introduction Charles Darwin (1809-1882)‚ a British naturalist‚ biologist and geologist who is known to be father of heredity and evolution. He proposed the theory that governs heredity known as theory of evolution and the process of natural selection

topic of “The effects of habit and of the use or disuse of parts; correlated variation; inheritance”(Darwin‚ p10). Darwin makes the observation‚ when speaking of domesticated mammals‚ that “not one of our domesticated animals can be named which has not in some country drooping ears...the drooping is due to the disuse of muscles of the ear‚ from the animals being seldom much alarmed”(Darwin‚ p10). Darwin argues that the increased use or disuse of parts in an animals lifetime result in heritable variation

Darwin spent five years exploring the world. Darwin traveled to many places mainly in the Southern Hemisphere. As he traveled from place to place‚ Darwin was surprised‚ by the similarities between the species. He wrote in his journal of the Galapagos Islands‚ "...there is even a difference between the inhabitants of the different islands; yet all show a marked relationship with those of America‚ though separated from that continent by an open space of ocean‚ between 500 and 600 miles in width."

Throughout the beginning of the nineteenth century there were two similar and still contrasting ideas of how evolution came to be. Both Charles Darwin and Jean-Baptiste Lamarck developed their own theories. First‚ Lamarck developed the Theory of Inheritance. He believed that living things had developed into what they were due to their environment. Lamarck thought living organisms developed characteristics to better suit their environment‚ such as the giraffe‚ that he assumed grew a larger neck in

of species from one another. Heredity is the mechanism that perpetuates variations‚ Darwin argues‚ as traits are passed from parents to offspring. What is important about these variations to Darwin‚ though‚ is the way they allow species to adapt and survive in the natural world. He gives numerous examples of variations that illustrate

Math Darwin‚ again‚ is very famous‚ or infamous‚ for his studies on finches. First he noted on the differences on the sizes of the birds. Their size accounts for certain elements that occur in nature. For instance‚ concerning islands (and how effective of an example they are) they have different habitats to live in. Certain islands have bigger predators‚ others have smaller or no predators at all. In island 1 the finch lives with the more predators‚ and therefore could grow larger than the predators

Charles Darwin. Charles Darwin was born on 12 February 1809 in Shrewsbury. Charles was brought up into a wealthy and well-connected family with many intelligent relatives. As Darwin grew up around these inspiring people he planned to follow a medical career and studied at the Edinburgh University but later switched to Cambridge. Darwin studied science and was determined to discover how the world evolved‚ other than what most people believed which was that God did it. As his knowledge grew Darwin invented

strength‚ survival skills‚ being able to reproduce on a large scale‚ and by adapting to harsh environmental conditions. This applies to all living organisms on the planet. Adapting and being able to change is what keeps a species from going extinct. Darwin proved this theory by doing experiments on finches on the Galapagos Island. He observed how finches would react to any challenge that were thrown their way. Some finches went extinct due to them not being able to keep up with the number of predators
