He observed that, since ages Giraffes have lived in places where the soil was arid and barren. Also, Giraffes faced competition from other herbivores like Antelopes, Elephants, etc. As a result, Giraffes had no option but to reach out to eat leaves from the untouched upper reaches of trees where other herbivores could not reach. These leaves were usually located at a much higher height than that of the Giraffe. Giraffes had to continuously stretch their neck in order to reach these leaves. Hence, Jean-Baptiste Lamarck concluded that Giraffes' long necks are a result of generation upon generation of repeated stretching and inheritance. Reference: Timecodes 0:00 - Why do Giraffes have
