Natural selection was established as the engine of adaptive evolution in the Modern Synthesis, owing to the elimination of alternative hypotheses. Lamarckism, particularly' mutational Lamarckism,' was one of the eliminated rivals, a theory that states that mutations may be directed toward developing phenotypes that increase an organism's performance in a certain environment. In contrast to this idea, the Modern Synthesis maintains that mutations are 'random,' despite the fact that the term's specific meaning has never been fully defined. Lamarck stated that evolution happened through the inheritance of acquired characters and traits. To put it in simpler terms, the theory states that changes are inherited through generations concerning the use and disuse of the organs or body parts of the organism. Lamarck was the first to provide a comprehensive theory of organic evolution, and he was the first to provide an elaborate explanation of it. This was an important moment in the museum's history as they had just lost the male elephant. The elephant's well-being had to do with Lamarck's findings, although it wasn't completely acknowledged at the point. We argue that the term "random mutation" refers to a triadic rather than a dyadic connection, present a new, formal, and exact definition based on the probabilistic idea of conditional independence, and lastly show how it might be used. The genetic specificity of the mutational process is not an essential requirement for the presence of mutational Lamarckism, according to our findings. So, the current review mainly focuses on innate mechanisms for genome modification, and their transgenerational effects.
