Abstract
En 中文
The microbiome is becoming recognized as a key determinant of host phenotype. Here, Henry et al. present a framework for building our understanding of how the microbiome also influences host evolution, review empirical examples and research approaches, and highlight emerging questions. The microbiome shapes many host traits, yet the biology of microbiomes challenges traditional evolutionary models. Here, we illustrate how integrating the microbiome into quantitative genetics can help untangle complexities of host-microbiome evolution. We describe two general ways in which the microbiome may affect host evolutionary potential: by shifting the mean host phenotype and by changing the variance in host phenotype in the population. We synthesize the literature across diverse taxa and discuss how these scenarios could shape the host response to selection. We conclude by outlining key avenues of research to improve our understanding of the complex interplay between hosts and microbiomes.
