Abstract

This article aimed to critically analyze mitochondrial evolution in bats by integrating evidence on bioenergetics, life history, molecular selection, phylogeny, and methodological limitations of mitochondrial DNA. It is a critical integrative review with a theoretical-analytical approach, based on scientific literature on molecular evolution, mitogenomics, comparative physiology, and phylogenetic methods. The analysis indicated that variation in mitochondrial evolutionary rates in Chiroptera cannot be explained by a single factor, such as metabolism, body size, or longevity, but rather by the interaction among molecular, physiological, ecological, phylogenetic, and methodological dimensions. A multifactorial conceptual model is proposed to interpret this variation. The study reinforces that mtDNA should be understood not only as an evolutionary marker, but also as a functional and historically conditioned genome.
