• Origin of Species, published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology.
• Lamarck gives use and disuse theory 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 the next generations.
• Hugo de Vries gives mutation theory which states that new species are not formed by continuous variations but by the sudden appearance of variations, which he named as mutations. Hugo de Vries stated that mutations are heritable and persist in successive generations.
• Biogenetic law, also called Recapitulation Theory, postulation, by Ernst Haeckel in 1866, that ontogeny recapitulates phylogeny that is the development of the animal embryo and young traces the evolutionary development of the species.
• Germplasm theory is given by August Weismann. According to his theory, germplasm, which is independent of all other cells of the body (somatoplasm), is the essential element of germ cells (eggs and sperm) and is the hereditary material that is passed from generation to generation.

Hence correct combination is a - 4, b - 3, c - 1, d - 5, e - 2.
