Research question(s): How specialized are the microbe lineages associated with mammalian guts? When a mammal adopts a diffferent diet, whow much does its gut microbiome resemble the microbiomes of its close relatives?


Microbes likely had commensal relationships with the ancestors of mammals, long before they evolve to give birth to live young or obtained many of the traits that charcterize the class of vertabrates today.
