Cover Story: Genomic complexity in bacterial endosymbiosis is examined using two metrics: Genomic Signature (GS) and Biobit (BB). These metrics quantify genomic changes as bacteria transition from free-living to symbiotic lifestyles, marked by genome reduction, gene loss, and increased AT content. Results reveal lower GS and BB values in endosymbionts, reflecting reduced complexity due to adaptation to intracellular environments. Factors influencing this reduction include gene loss, hapaxes, and diminished functional genomic elements. The findings advance understanding of the evolutionary mechanisms driving genome erosion in symbiotic bacteria and highlight the utility of GS and BB metrics for assessing genomic complexity. This research offers insights into bacterial adaptation and the trade-offs between genomic complexity and specialized lifestyles. View this paper
