(C) Jean-Baptiste Lamarck proposed the theory of inheritance of acquired characters. The most classic and widely cited example used to illustrate his theory is the evolution of the long neck in the African Giraffe. According to Lamarck,giraffes originally had short necks,but due to the continuous stretching of their necks to reach leaves on higher branches,their necks gradually elongated over generations,and this acquired trait was passed on to their offspring. Similarly,the loss of limbs in snakes is also often cited as an example of the 'use and disuse' theory,where snakes lost their legs due to disuse while crawling through narrow crevices. Therefore,both examples are associated with Lamarckism.
