Abstract: In
the last two decades, the widespread application of genetic and genomic
approaches has revealed a bacterial world astonishing in its ubiquity and
diversity. This review examines how a growing knowledge of the vast range of animal
– bacterial interactions, whether in shared ecosystems or intimate symbioses,
is fundamentally altering our understanding of animal biology. Specifically, we
highlight recent technological and intellectual advances that have changed our
thinking about five questions: how have bacteria facilitated the origin and
evolution of animals; how do animals and bacteria affect each other’s genomes;
how does normal animal development depend on bacterial partners; how is
homeostasis maintained between animals and their symbionts; and how can
ecological approaches deepen our understanding of the multiple levels of animal
– bacterial interaction. As answers to these fundamental questions emerge, all
biologists will be challenged to broaden their appreciation of these interactions
and to include investigations of the relationships between and among bacteria
and their animal partners as we seek a better understanding of the natural
world.
