To evolve, means to change with time over many generations.
Charles Darwins theory of evolution has been used to describe how human behaviour has changed over many years.
humans have adapted to the demands of individual environments.
darwins theory of natural selection
Seligman proposed the concept of biological preparedness. An inheritedpredisposition to fear certain types of animals, such as snakes and spiders.
Matchett and Davey (1991) linked animal fears to contamination risk and likelihood of attack.
What is natural selection?
The idea that any genetically determined behaviour that enhances an individuals chance of survival and reproduction will be passed on to the next generation natural selection takes part at gene level - survival of the fittest
Adaptive behaviours
People who are predisposed to avoid poisonous animals are more likely to survive
Where does natural selection take place
At the gene level
Example in psych - biological/adaptive preparedness
certain fears are adaptive that helped our ancestors survive
seligman proposed the concept that biological preparedness is inherited predisposition to increase likelihood of survival.
