Scientists have made the followingobservations: egyptian vultures use rocks to break open ostrich eggs, whichthey then eat. a vulture may search as far as 50 m away from an ostrich eggfor an appropriate rock (which is generally egg-shaped) to use tobreak the egg. the vulture then throws the rock at the egg untilthe egg cracks. this same rock-throwing behavior also occurs in youngcaptive-hatched birds that have not been exposed to rock-throwingadults. however, these naive vultures had to learn that the ostricheggs were a source of food. some scientists theorize that this behavior developed from thetactic of throwing smaller eggs to break them open. ostrich eggs, however, are too big to pick up and throw, so perhaps therock-throwing technique evolved in the vultures. this could explainwhy vultures choose rocks that are egg-shaped, rather than onesthat are jagged or irregular. based on the scientists� observations and your knowledge ofanimal behavior, which of the following statements are true? select all that apply. the shape of the rock that the vultures chooseis modified by their experience. egyptian vultures must imprint on their ownspecies in order to crack eggs using rocks. questioning whether the rock-throwing behaviorarose from egg-throwing relates to ultimate causation. rock-throwing in vultures is an innatebehavior. examining the anatomical mechanism that enablesegyptian vultures to throw rocks relates to proximatecausation. in egyptian vultures, eating ostrich eggs is alearned behavior. pecking at eggs to break them open is anexample of tool use.
