If Lamark and Darwin had debated why giraffes have such long necks how would their explanations differed?
Lamarck would have said that the ancestors of modern-day giraffes had short necks but stretched their necks as they tried to reach leaves in trees; so, their descendants were born with longer necks. Darwin would have said that in a population of ancestral giraffes, some had slightly longer necks than others; the long-necked giraffes were better able to feed on tree leaves and as a result produced more offspring. Over time, the proportion of longnecked giraffes in the population increased.
