Solution:

Lamarck incorporated two ideas into his theory of evolution, in his day considered to be generally true: Use and disuse - Individuals lose characteristics they do not require (or use) and develop characteristics that are useful. Darwin first used Spencer's new phrase "survival of the fittest" alongside "natural selection" in the fifth edition of On the Origin of Species, published in 1869, intending it to mean "better designed for an immediate, local environment". Stanley Miller, the chemist who was famous for his spark discharge experiment and the findings of the first-ever modern equipment and confirmed that the reaction created peptides. De Vries Hugo Marie a Dutch botanist who studied evolution by observing mutations rather than natural selection. He was an early proponent of the works of Gregor Mendel.
