lamarkism is a theory of evolution proposed by the french naturalist jean-baptiste lamarck in the early 19th century. the theory states that inherited characteristics acquired by an organism during its lifetime can be passed down to its offspring. this means that the traits an organism develops over its lifetime, such as increased muscle strength from exercise, can be passed down to future generations. lamarck's theory was later discredited by the work of charles darwin and gregor mendel, who proposed the theory of natural selection and the theory of genetics, respectively.
