¹D = discrete comparative method; C = continuous comparative method.

²Inference of positive selection assuming no variation between lineages.

³Two genes (SEMG1 and SEMG2) have been examined in multiple studies—SEMG1 twice [1, 68] and SEMG2 three times [1, 56, 68]. The “total (unique genes)” row reflects this replication and is therefore not a sum of the preceding rows.
