^aNotes: Branches (see Fig. 3 for branch numbers) that were inferred to be under episodic diversifying selection;

^bmean ω is the average dN/dS estimated for each branch under the free-ratio MG94 × REV model (no site-to-site rate variation);

^cω⁻ and

^dq⁻ values reflect the strength of negative selection (ω⁻ ) and the proportion of the total branch length affected by negative selection (q⁻);

^eω^N and

^fq^N -values reflect (nearly) neutral evolution (ω^N) and the proportion of the total branch length affected by (nearly) neutral evolution (q^N);

^gω⁺ and

^hq⁺ -values reflect the strength of positive selection (ω⁺) and the proportion of the total branch length affected by positive selection (q⁺);

ⁱLRT is the likelihood ratio test statistic;

^jp is the uncorrected P-value;

^kcorrected p is the probability based on Holm’s multiple testing correction.
