FAQ About Jean-Baptiste Lamarck

One of the most famous examples used to illustrate Lamarck's theory of acquired characteristics is the giraffe's neck. Lamarck hypothesized that ancestral giraffes stretched their necks to reach higher leaves, and as a result, elongated necks were passed on to future generations. Another example is the blacksmith's muscles, where he suggested that a blacksmith's developed muscles from work could be inherited by his offspring.
