My speculation amounts to this, the increase of the prevalence in pretty boys signals a possible decrease in sexual dimorphism which would indicate selection toward monogamy. However, I find this hard to believe since rates of infidelity and divorce are much higher than they were only 70 years ago; sexual debut amongst teenagers seems to be earlier and earlier with each passing day (something typical of r-selected behaviour). I find this quite perplexing as to why there might be an increase in androgyny but a simultaneously shift away from monogamous behaviours. I was wondering if any of you had any ideas that could possibly remediate this seemingly contradictory set of events.

: Perhaps we can refer back to CSR selection model? [[Life history theory]] has some new hypothesis on the discrepency between stabilty and polygamy. People who supports monogamy are often more sexually dimorpic, whilst those that are more hypergamous are more likely to be biologically masculinized (female selectivity increases as her Digit Ratio increases), constrastly those that are more polygamous are more likely to be biologically feminized.
