The theory of Lamarck was based on the principle of acquired characters. According to the theory, if an organism of a particular generation acquires certain characteristics due to their surrounding environment, it passes them to the next generation.
According to de Vries' mutation theory, living organisms can develop changes to their genes that greatly alter the organism. These changes are passed down to the next generation which lead to the development of new species. Once a new species has evolved, it becomes fixed and stops changing.
