Darwin Theory of evolution Darwin's concept of natural data that they collect. As he traveled to the coast survey vessel along the continents around the world. A survey along the coast of South America and the Islands in the Pacific Ocean, Darwin found that plants and animals on the continent and the Islands are similar, but not identical. Darwin observed 13 species of birds found fin Found on kalapakot Island, which is located in the Pacific Ocean, with Zhong ayapak with different sizes and different shapes. The suitability of each type of food that the birds eat.These birds are very similar to the birds on the Mainland. He believed that these birds have shared ancestors is living on South America but has been moved to the local Islands and a separate move in to live with different options according to the environment. Once more there is a long period of evolution, the change into birds. New species In the theory of evolution, Darwin Natural selection (Natural Selection) is an important mechanism that causes changes in the populations of living organisms. A single species in which this change led to the birth of new things she totpi she's Aston Villa. Darwin proposed natural selection mechanism based on observations, which is the nature of life on Earth is. 1. increasing population living organisms tend to produce a lot of balls version. Have a population too large (Over population).2. competition (Competition), there is a member of the tournament of the population to survive the competition. Rapid's resources are limited in a particular environment, especially the small island to compete for what is needed in life, like food, etc. 3. the variability of the characteristics of the population are members (Variation) differ in other aspects of the appearance of this difference can be sent to the child version. From the observations above. When resources are limited, there are a lot of the population will have to compete for the rapids. Only those members in the environment will survive live (to produce Survival) and reproduction, producing offspring in the future versions will have the opportunity to send their children to a feature version of fried. As a result, there is a change in population occurred until an evolution of a new species.Summarized by the concept of Darwin is a variety of life on earth comes from the species to inherit the characteristics of primitive species by the mechanisms that caused the change is a natural process and requires a long period of time.
