Mate preference changes depending on the strategy being used: when searching for a long-term mate, women often tend to emphasise resources, but in the short term, a potential mate's physical attractiveness is weighed more heavily because it is a good indicator of desirable genes.
One element of David Buss' research involves studying the differences in mate selection between short-term and long-term mating strategies. Individuals differ in their preferences according to whether they are seeking a short or long-term mating strategy (i.e. whether they are looking for a "hook-up" or for a serious relationship).
[14] [16] Even female waved albatrosses, which typically mate for life, are sexually promiscuous, with 17% of young fathered by extra-pair males.
