Abstract
This chapter outlines the history of molecular evolutionary research in australidelphian marsupials, along with the genetic and genomic advances that have provided insights into the evolution, phylogenetic relationships, adaptation, diversification, development, and conservation of Australasian marsupials. Marsupials have long been a focus of molecular evolutionary research, on account of unique features such as their specialized reproduction, ancient divergence, Gondwanan distribution, and evolutionary convergence with eutherians. Research into molecular evolution in australidelphian marsupials has aimed to: (i) reconstruct their evolutionary history; (ii) understand the mechanisms of molecular and functional evolution; and iii) characterize intraspecific diversification and fine-scale population dynamics to inform conservation management. To address any question in evolutionary biology, a sound framework of the evolutionary history and relationships of taxa is required. Molecular data have been a key source of data for resolving the phylogenetic relationships and timing of divergence of species, as well as the evolutionary processes driving the diversification of Australasian marsupials. Considerable progress has been made in recent decades, and the rapid growth of genome sequence data presents a valuable source of information about marsupial evolution. This chapter explores the growing understanding of molecular evolution in australidelphian marsupials and the insights gained from both individual and comparative studies.
