Therefore, it is known as the inheritance of acquired characteristics, and this theory of evolution was well accepted and honoured by the scientific world until Charles Darwin introduced the natural selection . These characters are inherited by their offspring as well. Darwin's theory has been supported by a lot of evidence. Abstract. Abstract. The first is by experiment. On the Inheritance of Acquired Traits and the Theory of Use and Disuse. The French view gives him more influence, firstly because he may have inspired Darwin as an eloquent writer on the topic of adaptive radiation, the father of the adaptive radiation theory, and secondly because a glimmer of Lamarckism can be found in the new discoveries of Epigenetics, non genetic inheritence. What is the difference between Darwinism and Lamarckism . Charles Darwin's On the Origin of Species described in great . They are not consistent because inheritance of acquired characteristics demands a reverse flow of information, which violates the central dogma. It is also commonly referred to as the theory of adaptation equated with the evolutionary theory of French .

The change in environment greatly affects the habit, habitat and composition of living organisms.
