Document Summary

Demonstrates higher fitness (because they are costly to produce) Reduces transmission error (increases probability of understanding the message) Easier to detect if someone is faking a trait (ex. faking masculine voice) Ornaments take extra energy and metabolism, therefore producing more than one is costly. Moreover, evolution is cheap and doesn"t want to do things that aren"t worth the effort. People with a preference for masculine faces were more likely to like the smell of pheromones. Short term relationships are positively correlated with preference for masculinity. Long term relationships are negatively correlated with preference for masculinity. Positively correlated > higher self related attractiveness leads to higher preference for masculinity. Preference for masculinity goes down when in less fertile phases. Positive correlation, therefore as people age their preference for masculinity increases. This is likely to ensure mate is of similar age. Masculinity is dependent on hormone level and tells us about dominance/long term health.
