Some studies on roosters have suggested that birds can adequately regenerate some parts of the limbs and depending on the conditions in which regeneration takes place, such as age of the animal, the inter-relationship of the injured tissue with other muscles, and the type of operation, can involve complete regeneration of some musculoskeletal structure. If large birds in the American wilderness kill and eat deer why do they not do this to lone humans out walking? But humans, despite being the rulers of Earth, can't regenerate lost appendages.
