Charles Darwin came up with the theory of evolution to explain the diversity, complexity, and origin of life. According to Darwin evolution takes place via Natural selection. Natural selection can explain diversity with in species, but I have yet to see anything that could make me believe that natural selection can create new species, or the origin of life. Natural selection is a natural process in which animals better adapted to their environment tend to survive and produce more offspring. This increases the percentage of their genes in the gene pool. Animals which are lesser suited tend to die earlier and as a result produce fewer offspring, therefore the genes they carry tend to diminish within the population. Natural selection helps species of animals survive. A species chance of survival increases because animals, which have defects, tend to die earlier thereby producing fewer offspring, while the animals with "beneficial" genes will tend to live longer and produce more offspring. Natural selection becomes most important when the environment of a species changes.
In contrast to microevolution, demonstrated by the peppered moth case and dog breeding macroevolution requires the changing from of one fundamental kind of animal into another. This process requires the generation of new genetic material. In the case of the peppered moths, there was no new genetic material created. Some moths had genes that produced black coloring, while others had genes that produced white coloring. The environment was acting on the population to change the proportion of black moths to white moth. Charles Darwin first told the world his revolutionary concept about how livings things develop. Evolution through natural selection and adaptation was the basis of his argument, as it remains to this day a debated subject by many. Darwin's theory does explain the evolution within species, but it has yet been proven to be the generator of new species. If this was the case than there would be many different species of dog. Dogs have been bread for centuries to express desired characteristics. Despite their vast differences between breeds they are all still the same species, and share the
