For instance, the sequencing of 12 Drosophila genomes has allowed researchers to identify new protein-coding genes, non-coding RNA genes, and regulatory motifs by analyzing evolutionary signatures. Similarly, HTS has been instrumental in the genomic analysis of viral populations, leading to the discovery of new viruses and a deeper understanding of their genetic diversity (Pérez‐Losada et al., 2020). The application of HTS in non-model organisms has also provided significant insights into evolutionary biology, revealing patterns of recombination and the role of population size in adaptive evolution. 6.1.2 Comparative genomics in evolutionary studies Comparative genomics involves the analysis of genome sequences from multiple species to understand the evolutionary processes shaping genomes. This approach has uncovered the role of natural selection in genome evolution and the functional divergence of protein-coding genes across different lineages (Gouy et al., 2017). Comparative genomics has shown that the ratio of nonsynonymous to synonymous substitutions varies among species, supporting the nearly neutral theory of molecular evolution. Additionally, the study of 12 Drosophila genomes has provided guidelines for comparative studies, highlighting the importance of species divergence and the number of species compared in enhancing discovery power. The integration of comparative genomics with other high-throughput technologies has further expanded our understanding of gene regulatory networks and their evolution (Fernandez-Valverde et al., 2018). 6.2 Proteomics and functional analysis 6.2.1 Mass spectrometry in protein identification Mass spectrometry (MS) is a powerful tool for the identification and characterization of proteins. It allows for the precise measurement of protein masses and the identification of post-translational modifications. The integration of MS with high-throughput sequencing technologies has enabled the comprehensive analysis of proteomes, providing insights into the functional states of individual cells and the identification of new proteins (Shapiro et al.,2013) This approach has been particularly useful in understanding the functional roles of proteins in various biological processes and their evolutionary significance. 6.2.2 Functional characterization of new proteins The functional characterization of new proteins involves determining their roles in cellular processes and their contributions to phenotypic traits. Advances in high-throughput sequencing and proteomics have facilitated the identification of gene regulatory networks and the interactions between genes that govern cell differentiation and development (Fernandez-Valverde et al., 2018). For example, the analysis of gene networks has revealed the polygenic basis of adaptation to high-altitude in human populations, highlighting the importance of multiple genetic components in the evolution of complex traits. These findings underscore the significance of functional characterization in understanding the evolutionary dynamics of new genes and their impact on development. 6.3 CRISPR technologies for studying new genes CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) technologies have emerged as powerful tools for genome editing and the study of gene function. By enabling precise modifications of the genome, CRISPR allows researchers to investigate the roles of specific genes in development and evolution. The application of CRISPR in functional genomics has provided new opportunities for the systematic analysis of gene regulatory networks and the identification of key regulatory elements (Zhang, 2024). This technology has the potential to revolutionize our understanding of gene function and the mechanisms underlying evolutionary change. 7 Conclusion The study of new gene recruitment in development and evolution has unveiled several critical insights. New genes significantly contribute to phenotypic evolution and are often integrated into rapidly evolving pathways such as spermatogenesis, immune response, and brain development. The integration of new genes into gene-gene interaction (GGI) networks follows a gradual process, starting from peripheral positions and eventually becoming central hubs with essential functions. Functional shifts, where genes acquire new roles, are pivotal in generating
