Q

what is status competition?

males will partake in risk behaviour such as violence even if they involve the possibility of death or injury this because females are attracted to this as they are willing to show that they will protect resources

Q

2 strengths of evolution as an explanation of aggression

A

SUPPORTING EVIDENCE
scientific credibility is high as supporting evidence is vast
demonstrates that it is falsifiable and that physical change will happen when they adapt to their environment
DARWIN widely accepted (finches from the galapagos islands)
BUT fossils only show physical not behavioural changes

aggression has evolved such as in Wilson and Daly in their analysis in detroit…social conflict is showing off jealousy

Q

What are 3 weaknesses of evolution as an explanation of aggression

A

scientific credibility is lowered as difficult to test idea that aggression evolved as vital survival behaviour… we cannot empirically test and that it can be explained better socially

reductionist- fully explained by aggression?
overlook social and cognitive factors…lowers validity since it is NOT complete

deterministic- suggesting humans have little free-will in choosing aggressive response and it is beyond our control
