Lamarck was one of the first scientists to understand that changes occur with time, and that changes are an adaptation to the environment. Answer.

Material that is represented in memory can be characterized by both its storage strength - the degree to which the information is embedded and integrated within the larger memory context - and the degree to which that information is actually retrievable. Variation differences in traits of organisms in a population Theory of Evolution states that evolutionary change comes through the production of variation in each generation and differential survival of individuals with different combinations of these variable characters.
