I mark into one another longitudinal and you will mix-sectional facts of varied procedures. In many cases, we provide good empirical screening away from certain predictions or effects. Some days, the fresh new readily available evidence will bring just licensed assistance, first surface or prima-facie plausibility. Of course, coming functions will discover the idea trying to find and you will particular hypotheses wrong. In conclusion, we (i) compare the fresh conditions beneficial towards spread out-of monogamous rather than polygynous relationships, (ii) thought solution hypotheses towards give of monogamous relationship, and you will (iii) speculate about precisely how relationship options is attached to the go up off popular associations and you will commercial financial development.
