人类学记录的证据表明，在大多数人类社会中，父母控制着后代的交配机会。基于这些数据，最近提出了一种性选择模型，其中与女性和男性选择一起，父母选择构成了我们物种中重要的性选择力量。人们发现这个模型可以很好地解释觅食社会典型的交配模式。通过使用标准跨文化样本的数据，本研究旨在检验该模型是否也可以解释农牧社会典型的交配模式。此外，还对不同社会类型进行了比较，并测试了两个模型衍生的假设。首先，假设在非觅食社会中，父母对后代的择偶选择有更多的控制权。其次，假设男性父母在农牧社会中比在狩猎采集社会中拥有更大的决策权。这里提出的结果支持这两种假设。还探讨了这些发现的进化意义。 (C) 2010 Elsevier Inc. 保留所有权利。
Evidence from the anthropological record indicates that in most human societies, parents control the mating access to their offspring. Based on these data, a model of sexual selection has been recently proposed, whereby along with female and male choice, parental choice constitutes a significant sexual selection force in our species. This model was found to provide a good account for the mating patterns which are typical of foraging societies. By employing data from the Standard Cross Cultural Sample, the present study aims at examining whether this model can also account for the mating patterns typical of agricultural and pastoral societies. In addition, comparisons between different society types are made and two model-derived hypotheses are tested. First, it is hypothesised that parents have more control over their offspring's mate choices in non-foraging societies. Second, it is hypothesised that male parents exert greater decision making power in agropastoral societies than in hunting and gathering ones. Both hypotheses are supported by the results presented here. The evolutionary implications of these findings are also explored. (C) 2010 Elsevier Inc. All rights reserved.
