What is use and disuse?

work of Lamarck In genetics: Preformation and natural selection. He enunciated the law of use and disuse, which states that when certain organs become specially developed as a result of some environmental need, then that state of development is hereditary and can be passed on to progeny.Click to see full answer. Subsequently, one may also ask, what is use and disuse theory?The use or disuse theory explains that the parts of an organism that the organism uses most will undergo hypertrophy and will become more developed. Hypertrophy is the growth of a specific organ or tissue.Subsequently, question is, who propounded the theory of use and disuse? ‘Use and disuse’ theory in human life. The French biologist Jean-Baptiste Lamarck (1744-1829) advocated the idea that animals acquired characteristics after using certain physical traits constantly. Beside above, is use and disuse correct? Explain Lamarck’s theory of use and disuse of organs. If an organ is disused, it may disappear in future generations. We do not agree with the model of use and disuse as proposed by Lamarck because it suggests that the modifications an organism acquires in its lifetime can be passed along to its offspring.What are Lamarck’s two laws?Lamarck’s “Second Law” stated that all such changes were heritable. The result of these laws was the continuous, gradual change of all organisms, as they became adapted to their environments; the physiological needs of organisms, created by their interactions with the environment, drive Lamarckian evolution.
