Measurable evolution occurs in laboratory populations of Drosophila under strong natural selection. The rate of adaptation to the experimental environment is significantly greater in populations with genetic variability increased by radiation than in the control, nonirradiated populations.
在强烈的自然选择下,果蝇实验室种群会发生可测量的进化。与未受辐射的对照种群相比,因辐射而增加了遗传变异性的种群对实验环境的适应速率明显更快。
