Table 1 Results of likelihood ratio test of hypotheses of positive selection on LAEWC trait shift. The result shows that most LAEWC related genes were not positively selected during the trait shift of LAEWC except the CER1 under the hypothesis 1 (positive selection independently acted on the gain of LAEWC)
