我们研究了在恒定或波动温度下进化的黑腹果蝇种群的发育可塑性的进化。与理论一致的是，在恒定的16℃或25℃下进化的基因型在该温度下提高和测试时表现最好。在温度波动中进化的基因类型在任何一种温度下都表现得很好，但只有在相同的温度下培养和测试时才能表现良好。我们的结果证实了理论预测的进化模式，包括在恒定环境中失去可塑性和专业化的好处。
We studied the evolution of developmental plasticity in populations of Drosophila melanogaster that evolved at either constant or fluctuating temperatures. Consistent with theory, genotypes that evolved at a constant 16°C or 25°C performed best when raised and tested at that temperature. Genotypes that evolved at fluctuating temperatures performed well at either temperature, but only when raised and tested at the same temperature. Our results confirm evolutionary patterns predicted by theory, including a loss of plasticity and a benefit of specialization in constant environments.
