Abstract (IBN 9423593) West, Meredith Experimental evidence has shown that many animal species show natal populational preferences with respect to reproductive patterns. In the present research, an avian model of cultural evolution is used to explore how social learning may be implicated in such reproductive patterns. Different populations of subjects are exposed for extensive periods to distinctive social populations prior to their breeding seasons. The reproductive preferences are then tested. Measurements are made of the proximate dynamics of the development of individuals' preferences. In addition, the behaviors by which individuals communicate reproductive preferences, in particular, the use of vocalizations and responses to vocalizations, are measured. Preliminary results confirm that social learning exerts direct effects on the transmission of reproductive preferences. The proposed studies explore in more depth the nature of the learning mechanisms and test whether learned preferences can be passed on to subsequent generations of individuals. If such cultural, transgenerational transmission occurs, current theories and concepts of the role of genetic programs in guiding and determining reproductive outcomes will have to re-evaluated. New theories will have to incorporate the exogenetic or cultural mechanisms deriving from models of social learning. In that human societies show analogous dependence on cultural transmission, the results of these studies will provide a new and more ecologically appropriate model of the evolution of complex behavior.

摘要(IBN 9423593)West，Meredith实验证据表明，许多动物物种在繁殖模式方面表现出出生的种群偏好。在这项研究中，文化进化的鸟类模型被用来探索社会学习如何与这种生殖模式有关。在繁殖季节之前，不同的受试者会在很长一段时间内接触到不同的社会群体。然后对繁殖偏好进行测试。衡量的是个人喜好发展的最近的动态。此外，还测量了个体传达生殖偏好的行为，特别是发声的使用和对发声的反应。初步结果证实，社会学习对生育偏好的传递有直接影响。拟议的研究更深入地探讨了学习机制的性质，并测试了习得的偏好是否可以遗传给后代。如果发生这种文化、跨代传播，目前关于遗传程序在指导和决定生殖结果方面的作用的理论和概念将不得不重新评估。新的理论将不得不纳入从社会学习模式中衍生出来的外生或文化机制。由于人类社会对文化传播表现出类似的依赖，这些研究的结果将为复杂行为的进化提供一个新的、更生态上合适的模型。
