个体繁殖的时间和我们认为他们应该繁殖的时间之间的不匹配一直是进化生态学中的一个长期问题。Price等人是这一领域的经典理论论文，被引用的主要原因是其最明显的结果：如果营养状况高的个体早育，那么在缺乏营养状况信息的情况下，早育的优势可能被高估。价格Al不太明显的结果是，平均而言，个体的繁殖时间要晚于最佳繁殖时间。在这里，我们从硬选择的角度解释了他们的非直观结果，并继续表明，如果允许育种日期和营养之间的关系发展，他们的结果都不会成立。通过引入这样的假设，即在高营养条件下，早期育种的优势更大，我们表明，他们最引的结果可以挽救。然而，平均而言，个体预期比最佳繁殖时间早，而不是晚。更一般地说，我们还表明，硬选择机制，支持这些结果有重大影响的可塑性的进化：当环境异质性变得太大，可塑性选择反对，禁止通才的进化。
The mismatch between when individuals breed and when we think they should breed has been a long‐standing problem in evolutionary ecology. Price et al. is a classic theory paper in this field and is mainly cited for its most obvious result: if individuals with high nutritional condition breed early, then the advantage of breeding early may be overestimated when information on nutritional condition is absent. Price at al.'s less obvious result is that individuals, on average, are expected to breed later than the optimum. Here, we provide an explanation of their non‐intuitive result in terms of hard selection, and go on to show that neither of their results are expected to hold if the relationship between breeding date and nutrition is allowed to evolve. By introducing the assumption that the advantage of breeding early is greater for individuals in high nutritional condition, we show that their most cited result can be salvaged. However, individuals, on average, are expected to breed earlier than the optimum, not later. More generally, we also show that the hard selection mechanisms that underpin these results have major implications for the evolution of plasticity: when environmental heterogeneity becomes too great, plasticity is selected against, prohibiting the evolution of generalists.
