Signals of selection (S from driftsel) for univariate traits at each time point for different groupings of populations.

RW = relative warp from analysis of morphology.Signals of selection (S from driftsel) for univariate traits at each time point for different groupings of populations.RW = 相对翘曲（relative warp），由形态学分析计算得到。数据集同时包含针对不同种群分组的单变量性状在各时间点下的选择信号，其中选择统计量S值取自driftsel工具。
