In Western societies, height is positively correlated with reproductive success (RS) for men but negatively correlated with RS for women. These relationships have been attributed to sexual selection: women prefer tall men, and men prefer short women. It is this success in the marriage market which leads to higher RS for tall men and short women. We have already shown that the relationship between height and RS for women is quite different in a non-Western context. In a subsistence farming community in rural Gambia, height is positively correlated with reproductive success for women, largely owing to the higher survival of the children of tall women. Here, the relationship between height and reproductive success is analyzed for men in the same community. For these Gambian men, there is no significant relationship between height and the number of children they produce, although tall men do contract more marriages than shorter men. We conclude that environmental context needs to be taken into account when analyzing human reproductive behavior.
在西方社会,身高与男性的生殖成功率(RS)呈正相关,但与女性的生殖成功率呈负相关。这些关系归因于性选择:女性偏好高个子男性,而男性偏好矮个子女性。正是在婚姻市场上的这种成功导致高个子男性和矮个子女性有更高的生殖成功率。我们已经表明,在非西方背景下,身高与女性生殖成功率之间的关系截然不同。在冈比亚农村的一个自给自足的农业社区,身高与女性的生殖成功率呈正相关,这主要是因为高个子女性的孩子存活率更高。在此,对同一社区的男性身高与生殖成功率之间的关系进行了分析。对于这些冈比亚男性来说,身高与他们生育的孩子数量之间没有显著关系,尽管高个子男性比矮个子男性缔结的婚姻更多。我们得出结论,在分析人类生殖行为时需要考虑环境背景。
