Document Summary
Tinbergen: bee wolves solitary predatory wasps capture bees to feed their young. When leaving burrow to find food they fly over area in progressively expanding set of loops. Rainy weather kept bees inside possibly because rain shifted landmarks outside of burrow. Placed pinecones outside burrow so bee wolf would use as landmark then moved so when bee wolf returned she landed at center of pinecones instead of at her burrow. Landmarks are important because every individual has unique burrow. Learning mechanisms are evolved adaptations to an organism"s natural environment. Innate behaviours are said to be instinctive; supposedly fixed or stereotyped not showing much variation from one individual to another. Learned behaviours more variable and shaped by experiences over lifetime of individuals. Learning occurs when behaviour is modified by experience. Evolution shapes learning with evolved traits and facultative adaptations. Deprivation experiment have provided best evidence against innateness can always find some type of deprivation that disrupt the behaviour.
