Such an explanation was proposed by Jean Babtiste Lamarck toward the end of the eighteenth century, and Lamarck became best known for his pre-Darwin theory of evolution. According to Lamarck, the acquired characteristics of the parents could be handed down to their offspring. Suppose, to take the most over used example, that the first generations of giraffe had a neck of ordinary length.
Because the lower branches of the trees they fed off were easily striped, these early giraffes stretched out their necks to reach higher branches. In doing
