Trading sex for resources

The title really says it all. Not much further commentary needed. Care for another example? How about bower birds?

Just Like Penguins And Other Primates, People Trade Sex For Resources
Female penguins mate with males who bring them pebbles to build egg nests. Hummingbirds mate to gain access to the most productive flowers guarded by larger males.

New research shows that even affluent college students who don't need resources will still attempt to trade sexual currency for provisions, said Daniel Kruger, research scientist at the University of Michigan School of Public Health.

The exchange of resources for sex---referred to by scientists as nuptial gifts---has occurred throughout history in many species, including humans, Kruger said. The male of the species offers protection and resources to the female and offspring in exchange for reproductive rights. For example, an arranged marriage can be considered a contract to trade resources.

However, the recent findings suggest that such behaviors are hard wired, and persist no matter how much wealth, resources or security that people obtain.
