将最近的染色体倒置频率样本与历史样本进行比较，提供了确定遗传变化是否在自然人口中跟踪气候变化的机会。我们确定了三大洲果蝇种群的染色体倒置频率和环境温度随时间(样本之间平均为24岁)变化的幅度和方向。在26个种群中，有22个种群的气候在间隔时间内变暖，而在这22个种群中，有21个种群的低纬度(温暖气候)的基因型频率增加。因此，这种苍蝇的基因变化正在跟踪气候变暖，并在全球范围内这样做。
Comparisons of recent with historical samples of chromosome inversion frequencies provide opportunities to determine whether genetic change is tracking climate change in natural populations. We determined the magnitude and direction of shifts over time (24 years between samples on average) in chromosome inversion frequencies and in ambient temperature for populations of the fly Drosophila subobscura on three continents. In 22 of 26 populations, climates warmed over the intervals, and genotypes characteristic of low latitudes (warm climates) increased in frequency in 21 of those 22 populations. Thus, genetic change in this fly is tracking climate warming and is doing so globally.
