简单增长模型中的数学混沌对理论生态学有着严重的影响。最近进行了大量的努力，以确定存在混乱的条件。对27种果蝇在2种温度下的混沌现象进行了实证研究。单物种实验室种群总是表现出动态稳定性。混沌和稳定的极限环行为是不适应的，并提出了一种稳定的群体选择发生的进化机制。
Mathematical chaos in simple growth models has grave consequences for theoretical ecology. Much effort has recently been directed towards delimiting the conditions under which chaos exists. An empirical search was performed for chaos among 27 Drosophila spp. at 2 temperatures. Single-species laboratory populations invariably exhibited dynamical stability. Chaos and stable limit cycle behavior are maladaptive, and an evolutionary mechanism is proposed whereby group selection for stability occurs.
