"So under nature with the nascent giraffe the individuals which were the highest browsers and were able during dearths to reach even an inch or two above the others, will often have been preserved; for they will have roamed over the whole country in search of food. That the individuals of the same species often differ slightly in the relative lengths of all their parts may be seen in many works of natural history, in which careful measurements are given. These slight proportional differences, due to the laws of growth and variation, are not of the slightest use or importance to most species. But it will have been otherwise with the nascent giraffe considering its probable habits of life; for those individuals which had some one part or several parts of their bodies rather more elongated than usual, would generally have
survived. These will have intercrossed and left offspring, either
inheriting the same bodily peculiarities, or with a tendency to vary again
in the same manner; while the individuals less favoured in the same
respects will have been the most liable to perish."

"Examples of Lamarckism would include:
Giraffes stretching their necks to reach leaves high in trees, strengthen and gradually lengthen their necks. These giraffes have offspring with slightly longer necks. "
