Research suggests that the microbiome plays a role in extending the evolutionary potential of its host. Studies have explored this concept in various contexts, including the gut microbiome of mammals and the microbiome of plants, with findings indicating that the microbiome can influence host behavior and adapt to environmental stressors. The microbiome's impact on host evolution appears to be driven by complex interactions between the microbiome and its environment, with potential applications in fields such as agriculture and microbiome manipulation.
