This study explores the critical role of new gene emergence in driving evolutionary innovation and biodiversity. The research reviews various mechanisms of new gene origin, such as gene duplication, de novo gene emergence from noncoding sequences, and the co-option of genomic elements. It focuses on how these genes are recruited into developmental pathways, leading to phenotypic changes and the evolution of complex traits, including brain development and reproductive behaviors. Using comparative genomics, studies of gene regulatory networks (GRNs), and high-throughput sequencing technologies to track gene function, the results show that new genes play a significant role in developmental innovation, adaptive evolution, and environmental adaptation. The study emphasizes the importance of new gene recruitment in understanding the dynamics of genetic networks and its broader implications for evolutionary biology. It suggests improving methods for gene identification and functional characterization, while expanding research to non-model organisms.
