Charles Darwin's theory of evolution by natural selection made us rethink our place in the world.

According to Charles Darwin, evolution is a very slow and gradual process. According to Dawkins, the chance of life spontaneously occurring on a planet is a billion to one…but this only refers to the basic “origin of life.” So what are the chances of more complex organisms, molecular structures and biological systems appearing on Earth by themselves? As we talk about the time period in evolution we usually refer to billions of years. After this introduction of natural selection, Darwin elaborated on the subject with his theory of evolution and his book, On the Origin of Species, published in 1859.His work with Darwin's finches and his ideas on survival of the fittest explained the mechanism of natural selection and how it could lead to a proliferation of many different kinds of organisms.
