Understanding the source, colonization rules, and dynamic evolution process of the gut microbiota is of significant importance for regulating host health, given its crucial role in nutrient metabolism, immune regulation, and intestinal barrier function. This article comprehensively reviews the composition and functions of the gut microbiota and explores the origins and transmission pathways, with a particular focus on the effects of maternal-infant transmission and paternal inheritance on the structure and functions of the gut microbiota. We chart microbial assembly across pivotal life stages, distill the driving factors involved in the community assembly process, and critically appraise the advances in metagenomic and source-tracking toolkits. The review provides an integrated framework for microbiome-targeted strategies aimed at reconstructing a health-oriented gut ecosystem.
