The theory is widely accepted based on fossil records, DNA sequencing, embryology, comparative anatomy and molecular biology. Darwin’s finches are examples of evolutionary adaptation.Many German biologists conceived of life evolving according to predetermined rules, in the same way an embryo develops in the womb. But in the mid-1800s, Darwin and the British biologist Alfred Russel Wallace independently conceived of a natural, even observable, way for life to change: a process Darwin called natural selection.
The behaviour of the individual changes that eventually change organ usage and organism development. This gradual change in the species in response to the environment is known as “transmutation of species”. Lamarckism was reformed by Giard and Cope by incorporating a few points of the opponents.

More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive. When reproductive isolation occurs new species will form.

Variation provides advantages to some members of a population. The surviving individuals pass their traits to the next generation.
The principles that result in natural selection are as follows: Variation – Individuals have varying traits in a population. Depending on whether or not these traits assist the organism to adapt to the changing environment determines the selection of the species for survival. Inheritance – The parents determine the character traits that are ...Individual show variation. 2. Variations can be inherited. 3. Organisms produce more offspring then can survive. 4. Variations that increase success will be more likely to be passed on to future generations.
