Document Summary
Basis of behaviour: assuming a genetic component, some human traits are genetically based, the learned and genetic aspects are a continuum, epigenetics: stamps that are put on the dna that will last a few generations. Plays an important role in parental care behaviour. Deprivation experiment: example: squirrel raise a squirrel in a container with no sand; deprived of nuts, and other materials. Must be raised on a good nutritional food. Place the squirrel in another container with nuts. The squirrel will grab the nuts and bury it in the ground. Thus this action is based on genetics: example: spiders web spinning. Spiders will weave a perfectly serviceable web. The ability to weave is found in their dna: example: kangaroo rat. Place a kangaroo rat with a rattle snake. The rat will jump far away and high even though they have never had any contact with rattle snakes.
