Detailed explanation-1: -Lamarckism, also known as Lamarckian inheritance or neo-Lamarckism, is the notion that an organism can pass on to its offspring physical characteristics that the parent organism acquired through use or disuse during its lifetime.

Detailed explanation-2: -Lamarck is best known for his Theory of Inheritance of Acquired Characteristics, first presented in 1801 (Darwin’s first book dealing with natural selection was published in 1859): If an organism changes during life in order to adapt to its environment, those changes are passed on to its offspring.

Detailed explanation-3: -In the case of the French biologist Jean-Baptiste Lamarck, his name since the end of the nineteenth century has been tightly linked to the idea of the inheritance of acquired characters.

Detailed explanation-4: -Lamarckism was proposed by Jean-Baptiste de Monet Lamarck in the year 1744-1829. This theory was based on the principle that all the physical changes occurring in an individual during its lifetime are inherited by its offspring.

Detailed explanation-5: -Darwinism emphasises the struggle for existence. Lamarckism discredits the struggle for existence. Only useful variations are transferred to the succeeding generation. All acquired traits are transferred to the next generation. Darwinism was built on the principle of survival of the fittest.
