Test of Models of Evolutionary Theory

这项研究允许新墨西哥大学的两位人类学家测试当代美国男性养育子女的其他模式。这项研究将测试一个特定的进化模型，该模型是关于男性生育能力和养育方式的决定因素，旨在解释男性拥有孩子的数量，男性在孩子身上投入的经济和非经济资源，男性和女性在生育能力、养育子女和交配决定方面的共性和利益冲突，以及兄弟姐妹中对后代的不同投资。其他经济和进化模型的预测也将受到考验。数据将通过对新墨西哥州阿尔伯克基50岁以上的750名盎格鲁和西班牙裔男性的代表性样本进行结构化访谈获得。一个简短的访谈将决定研究的资格，一个长访谈将获得三代人的生育、养育和收入数据。这项研究很重要，因为增加对生育率和养育子女的了解将有助于我们了解人口转型的原因，增加对美国不同种族生育率的了解可以帮助规划者设计政策，以满足不同人口的需求。

This research allows two anthropologists at the University of New Mexico to test alternative models of male parenting in the contemporary U.S. This study will test a specific evolutionary model of the determinants of male fertility and parenting practices, designed to explain the number of children men have, the economic and noneconomic resources men invest in their children, commonality and conflict of interest between men and women in fertility, parenting and mating decisions, and differential investment in offspring within sibships. The predictions of alternative economic and evolutionary models will also be tested. Data will be obtained through structured interviews with a representative sample of 750 Anglo and Hispanic men over 50 years of age in Albuquerque, New Mexico. A short interview will determine eligibility for the study, and a long interview will obtain fertility, parenting and income data on three generations of individuals. This research is important because increased understanding of fertility and parenting in general will help us understand the causes of the deomgraphic transition, and increased understanding of fertility in different ethnic groups in the US can help planners design policies to satisfy the needs of different populations.
