Supportive evidence of evolutionary explanations for relationships
-Buss 1989 ->Surveyed 10,000 adults in 33 countries where females reported valuing resources whilst men valued looks. Supports sexual selection.
-Waynforth and Dunbar -> used American newspapers ‘lonely hearts’ column, women tended to describe themselves physically but men described themselves in terms of resources etc.
Limitations of evolutionary explanations for relationships
-Temporal validity -> is socially sensitive as it promotes sexist behaviours. Alpha bias.
-Penton Voak et al -> suggests females preferences change across the menstrual cycle therefore suggesting the evolutionary exlaination is too specific
