^a These number means the species numbers involved in lineage-specific expansions
^b Corresponding species involved in the lineage-specific expansions
^c Not all lineage-specific expansions have been shown due to space limitation. The total number of other two-species-lineage-specific expansions is shown in this row (Please see Table S1 for the full version)
