This study explores the origin and evolutionary diversification of the Gossypium genus, integrating insights from taxonomic investigations, biogeography, molecular genetics, phylogenetic analysis, and archaeology. It highlights the genus's complex evolutionary history, including multiple instances of polyploid formation, interspecific hybridizations, and the domestication processes that led to the development of economically significant cotton species. High-quality genome assemblies of key species such as Gossypium hirsutum and Gossypium barbadense have provided detailed insights into the genetic and molecular bases for their divergence. Comparative analyses highlighted species-specific alterations in gene expression and structural variations. The findings underscore the importance of combining traditional botanical research with modern genomic technologies to unravel the intricate evolutionary pathways of Gossypium. By analyzing various studies, this study expect to provide insights into the phylogenetic relationships within the genus and the implications for cotton breeding and genetic improvement.
