that these organisms were related‚ but not identical. This led Darwin into believing that over time‚ organisms must adapt to suit their environment. He explained his theories thoroughly in his book‚ On the Origin of Species by Means of Natural Selection. Darwin decided it was possible for a species to change from one form and develop into another over time. This led him to the notion that all life forms were not fixed‚ but continuously changing or evolving. The other part of the theory was that

The term "sexual selection" was proposed by Darwin. He contrasted in a sense‚ natural selection sexual selection because‚ as he said‚ sexual selection occurs not as a result of the struggle for existence‚ as in the case of natural selection and the struggle for the possession of individuals of the same sex. And‚ as a rule‚ the struggle between the males for possession of the females. Since then‚ continuing fierce debate about this phenomenon - sexual selection‚ and still many researchers‚ for example

by the ability of an organism to survive and reproduce in an environment. Charles Darwin’s explanation of natural selection involves three principles. The first principle is variation which states that every species is composed of a great variety of individuals. Some of these individuals have adapted to their environment than others have. The second principle of natural selection is heritability. This is where offspring inherit traits from their parents in some degree or another. The third principle

The processes of natural and sexual selection can help to explain why modern-day human behaviour has evolved. There are many physical and psychological characteristics that all human beings‚ across cultures‚ display today that have evolved from our ancestors‚ over thousands of years. As a result of the selection process‚ we have adapted in particular ways

Darwin: Natural Selection The well known ecologist Charles Darwin exhibited the hypothesis of natural selection. He went on numerous trips to the wildlife‚ taking after his interest of the nature and the change that happens in the nature. After examining different kinds of living organisms‚ he clarified Natural Selection as "preservation of favorable variations and the rejecting of injurious variations."(900). Darwin utilized relations and demonstrations to show that distinctive changes happened

These changes would allow organisms to adapt to its environment‚ help it to survive and reproduce. Evolution by natural
