Table 2 Effects of life-history variables on mtDNA substitution rate in passerines (n = 88) vs. other bird species (n = 108) without (A) and with phylogenetic control (B).

From: The erratic mitochondrial clock: variations of mutation rate, not population size, affect mtDNA diversity across birds and mammals
