Telomere length, telomerase, lifespan, and body mass distributions. Telomere length (A and B) or telomerase (C and D) vs. log body mass (A and C) or lifespan (B and D). The probability of a significant relationship as an independent variable is indicated by the phylogenetic generalized least squares (PGLS) analysis, which takes into account phylogenetic relationships (which are not indicated in the figure). Telomerase is significantly inversely related to mass while telomere length is inversely correlated with lifespan. Most of the variability occurs within smaller shorter-lived species.
