(i) Divergent evolution;
(ii) Small variations occurred in feet of birds within the population; competition for limited food occurred in the environment; predation as a mode of feeding favoured birds whose feed had long; sharp and curved claw / talons; to kill prey / tear flesh of prey;
(iii) All birds had same length of feed; the (aquatic environment favoured long feet talons; leading to continuous natural use of the feet; which kept increasing in length; the longer trait was then passed on to offspring along the generations;
