ome scientists theorize that this behavior developed from the tactic of throwing smaller eggs to break them open. Ostrich eggs, however, are too big to pick up and throw, so perhaps the rock-throwing technique evolved in the vultures. This could explain why vultures choose rocks that are egg-shaped, rather than ones that are jagged or irregular.
Based on the scientists' observations and your knowledge of animal behavior, which of the following statements are true?
Select all that apply.
Pecking at eggs to break them open is an example of tool use.
Rock-throwing in vultures is an innate behavior.
Egyptian vultures must imprint on their own species in order to crack eggs using rocks.
In Egyptian vultures, eating ostrich eggs is a learned behavior.
Examining the anatomical mechanism that enables Egyptian vultures to throw rocks relates to proximate causation.
The shape of the rock that the vultures choose is modified by their experience.
Questioning whether the rock-throwing behavior arose from egg-throwing relates to ultimate causation.
