darwin 2

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.


The real question is not whether microevolution happens. It does, but can microevolution be the cause for large evolutionary change. In order for a new species to evolve there must be creation of new genes that did not exist before. Natural selection just optimizes the existing gene variation with in a particular species. Science now days use microevolution to explain macroevolution.

Some people see this example as proof of evolution, and explains the origins of life. Although this does prove Darwin theory of natural selection, it does not prove that one species can be derived from another. Sure the moths are now mostly black but they are still the same species of moth. There was no new genetic material made, only a change in what genetic material was expressed. This change within a species is called microevolution.

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
