The science of phylogenetics, and specially the subfield of molecular systematics, has grown exponentially not only in the amount of publications and general interest, but also especially in the amount of genetic data available. Modern phylogenomic analyses use large genomic and transcriptomic resources, yet a comprehensive molecular phylogeny of animals, including the newest types of data for all phyla, remains elusive. Future challenges need to address important issues with taxon sampling—especially for rare and small animals—orthology assignment, algorithmic developments, and data storage and to figure out better ways to integrate information from genomes and morphology in order to place fossils more precisely in the animal tree of life. Such precise placement will also aid in providing more accurate dates to major evolutionary events during the evolution of our closest kingdom.
