Many research scientists virtually agree as to the importance of an elucidation of evolutionary mechanisms as the unification for acquisition and assumption of information concerning the origin, history, and diversity of life on earth. Evolution is construed as an overall gradual development of living organisms from differentiated pre-historic to current times. It represents the process whereby modern organisms descend from ancient ancestors. Across decades of years, evidence from innumerable sources have indicated that the concepts put forth by Jean Baptiste de Lamarck and Charles Darwin represents the base of scientific research in the field of evolution. However, there are circumstantial evidence which proves that Darwin’s theoretical beliefs…show more content…
Lamarck’s theory of Inheritance of Acquired Characteristics has been disproved. This was done in two major ways. The first is by experimentation using the scientific method. We have seen numerous real life phenomenon and observed that changes that occur in an organism during life are not passed on to the offspring. If a dog’s back limbs are damaged and unusable, its offspring are still born with all legs usable. This and other such examples show that Lamarck’s theory does not explain how life formed and became the way it is. Secondly, Lamarck’s theory has been proven wrong by the study of genetics. Darwin knew that traits are passed on, but he never understood how they are passed on. During the time when Darwin published is first research on evolution, Gregor Mendel, who discovered genetics, was just starting his experiments. However, now we know extensively about genetics, and we know that the only way for traits to be passed on is through genes, and that genes cannot be affected by the outside world. The only thing that can be affected is which gene sets there are in a population, and this is determined by which individuals die and which ones live. Although Darwin won acceptance for evolution, his efforts to establish the validity of natural selection, his primary mechanism of evolution, were less
