The distinction between CA and BA and the progression of epigenetic clocks through multiple generations. (A) Chronological age reflects a uniform measure of time, whereas biological age reflects cellular and physiological decline. (B) First-generation clocks (e.g., Horvath, Hannum) were trained to predict chronological age. Second-generation clocks (e.g., PhenoAge, GrimAge) focus on phenotypic health and mortality risk. Third-generation clocks (e.g., DunedinPACE) measure the current rate of biological aging. The next generation of clocks aims to measure organ-specific biological age. Image adapted from Figure 1 in Cheema, B. S. et al. Functional, molecular, and digital measurements of biological age. The Journal of Clinical Investigation. 2026;136(12):e205777. doi:10.1172/JCI205777. Licensed under CC BY 4.0.
