The fundamental idea behind natural selection is that, within a particular environment, a genetically influenced trait tends to be more successful and thus able to survive and be passed on. environmental psychologists examine the that led to survival, and which then led to further reproduction for survival. it doesn't matter to environmental psychologists whether those behavioral tendencies are adaptive in today's environment.

I believe the answer is:  behavioral tendencies

behavioural tendencies refers to the uncontrolled behaviour that is untrained and often arise under a certain situation without we being aware of it.

This type of tendencies are integrated within our brain as a form of survival mechanism. Examples of behavioural tendencies would be the fact that we become extremely cautious when we experience a spike in adrenaline that increase our response and concentration when we feel that we're in danger.
