The term often leads into confusion, however, since international compact cars are somewhat larger than their North American equivalents, mostly because no supermini/subcompact size is manufactured by American, Mexican and Canadian car makers up to date.
By the late 1860's, Darwin came to describe this process as the survival of the fittest. This is very different from Lamarck's incorrect idea that the environment altered the shape of individuals and that these acquired changes were then inherited.
Social Darwinism applied the 'survival of the fittest' to human 'races' and said that 'might makes right'. Not only was survival of the fittest seen as something natural, but it was also morally correct. It was therefore natural, normal, and proper for the strong to thrive at the expense of the weak.
