Men marry younger women and women prefer to marry older men, in general.
But is it culture, genetics or the environment that drives such a choice—and is there an optimal age difference? New research shows that, at least for the Sami people of preindustrial Finland, men should marry a woman almost 15 years their junior to eifference their chances of having the most offspring that survive.
Yet, only 10 percent of these marriages were between men and women with that optimal age difference.
The span ranged from men marrying women as much as 20 years older to women marrying men as much as 25 years older; the average age difference between husband and wife was three years. Marriage customs or the availability of reindeer to support a new family the Sami people are husbaand herders might be the reason that more Sami marriages did not display the optimum age difference, Helle says.
Ultimately, it is the wire at which the woman begins bearing children that is the biggest factor in survival, the paper in Biology Letters suggests: Younger women, in general, bear more healthy children.
Marrying an older woman or much older man proved the most detrimental to reproductive success.Bi Latin Man
Other research in modern day Sweden has shown that the ideal reproductive match is for a man to marry a woman six years his junior. But the cultural constraints on marriage may have changed.Lady Wants Sex Basehor
