最近的学习和进化之间的相互作用模型表明，学习提高了种群在固定环境中找到最优解的速度。然而，学习能力只在可变的环境中才有优势。在这项研究中，数量遗传学模型被用来研究个体学习对进化的影响。构造了两个学习个体的种群模型并进行了分析。在第一个模型中，学习的效果表示为选择方差的增加。在固定环境选择和可变环境选择下，导出了学习个体种群的动力学方程和平衡条件。在第二个模型中，个体学习努力的量由第二个基因调节，该基因指定关键学习期的持续时间。第二模型包括学习过程的模型，以确定在学习期间累积的个体健身成本和收益。然后选择个人进行最佳学习投资。从这两个模型的结果的相似之处表明，学习对进化的净效应是相对独立的学习过程的机制。(C)1995年学术出版社
Recent models of the interactions between learning and evolution show that learning increases the rate at which populations find optima in fixed environments. However, learning ability is only advantageous in variable environments. In this study, quantitative genetics models are used to investigate the effects of individual learning on evolution. Two models of populations of learning individuals are constructed and analyzed. In the first model, the effect of learning is represented as an increase in the variance of selection. Dynamical equations and equilibrium conditions are derived for a population of learning individuals under fixed and variable environmental selection. In the second model, the amount of individual learning effort is regulated by a second gene specifying the duration of a critical learning period. The second model includes a model of the learning process to determine the individual fitness costs and benefits accrued during the learning period. Individuals are then selected for the optimal learning investment. The similarities of the results from these two models suggest that the net effects of learning on evolution an relatively independent of the mechanisms underlying the learning process.
