n, 2Δℓ, ω, and p₁ are utilized as in Table 1. BEB Sites are the number of sites identified as being under positive selection using model M8 in PAML and a posterior probability threshold higher than 95%. TreeSAAP Sites are the number of positively selected sites as identified by TreeSAAP with the number of sites shared with PAML in brackets. Significance of the 2Δℓ test statistics is depicted as in Table 1.
