Keywords: human, fecundity, lifetime reproductive success, mate choice, sexual selection. This pattern suggests that the survival and/or fertility of men did not strongly constrain marital fitness among Sami (see also Kär., 1998 ). Availability of mates and resources). These registers consist of continuous baptism, burial and marital records of Sami who practised reindeer herding, fishing and hunting for their livelihood (. Yet, very little is known of the actual fitness consequences of such mate preferences in terms of the lifetime reproductive success. LRS was used because in these natural mortality populations, child mortality may have inflated any fitness estimates based on offspring numbers only. However, although remarriage was a rather rare event among Sami, only men were able to increase their fitness through remarriage, since men but not women (due to menopause) were able to lengthen their reproductive lifespan by remarriage ( Kär.

The clean shaven look proved most popular with 120 matches. We also investigated how well the realized parental age difference in the population corresponded to the age difference that maximized marital fitness among these Sami. It was obvious in most cases that they were looking for a quick hook-up rather than a boyfriend. Of course, it is important to highlight that Southerst's study was a social experiment and, while his findings were assured, there are various factors that could affect the difference in matches including the time of day and day of week the images were posted and how much. In fact, the study, which was carried out for.
