BOTANY

Detailed explanation-1: -Lamarck’s hypothesis has never been proven experimentally and there is no known mechanism to support the idea that somatic change, however acquired, can in some way induce a change in the germplasm.

Detailed explanation-2: -Lamarck’s Theory of Inheritance of Acquired Characteristics has been disproved. This was done in two major ways. The first is by experiment. We have seen through many real examples and observations that changes that occur in an animal during life are not passed on to the animal’s offspring.

Detailed explanation-3: -It is correct that evolution occurs over generations of reproduction, but Lamarck was incorrect in thinking that traits developed over a lifetime will be passed along to offspring. The correct mechanism of inheritance is that genes are passed along from generation to generation.

Detailed explanation-4: -The reason we no longer believe Lamarck’s version is that genetic material is transmitted to the next generation through germ cells, and most acquired changes simply do not influence germ cells; they are, to a large extent, isolated from the environment.
