Introduction
The hologenome theory is a postulate put forth in 2007 by Eugene Rosenberg and Ilana Zilber-Rosenburg stating that the object of genomic natural selection is not a single organism, but the organism and its microbial communities (Rosenburg et al., 2007). This theory was originally based on the pair’s observations of Vibrio shiloi-mediated bleaching of the coral Oculina patagonica (Rosenburg & Zilber-Rosenburg, 2008); since its first introduction, the theory has been promoted as a fusion of Lamarckism and Darwinism (Rosenburg, Sharon, and Zilber-Rosenburg, 2009) and expanded to all of evolution, not just that of corals (Rosenburg & Zilber-Rosenburg, 2011). Recent research by the Rosenburg lab suggests that commensal bacteria play a role in mate choice by the fruit fly, Drosophila melanogaster, further supporting the hypothesis that greater genetic trends are determined by symbiotic microbiota (Sharon et al., 2010).
