Microbiome evolution along divergent branches of the vertebrate tree of life: what is known and unknown

Vertebrates harbour microbes both internally and externally, and collectively, these microorganisms (the 'microbiome') contain genes that outnumber the host's genetic information 10-fold. The majority of the microorganisms associated with vertebrates are found within the gut, where they influence host physiology, immunity and development. The development of next-generation sequencing has led to a surge in effort to characterize the microbiomes of various vertebrate hosts, a necessary first step to determine the functional role these communities play in host evolution or ecology. This shift away from a culture-based microbiological approach, limited in taxonomic breadth, has resulted in the emergence of…
