Detailed explanation-1: -According to Lamarck, organisms altered their behavior in response to environmental change. Their changed behavior, in turn, modified their organs, and their offspring inherited those “improved” structures.
Detailed explanation-2: -Lamarck proposed in 1802 the concept that environment can directly alter phenotype in a heritable manner. Environmental epigenetics and epigenetic transgenerational inheritance provide molecular mechanisms for this process. Therefore, environment can on a molecular level influence the phenotypic variation directly.
Detailed explanation-3: -Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime-such as greater development of an organ or a part through increased use-could be transmitted to their offspring.
Detailed explanation-4: -In it, he presented a theory of evolution that included two driving forces, a natural tendency towards increasing complexity and an adaptive force powered by use and disuse.
