Lifespan is log10-transformed. r is the Pearson and ρ the Spearman rank correlation across species. q corrects the p-value for testing 1,331 features at once (Benjamini–Hochberg); green marks q < 0.05.

PIC r uses phylogenetically independent contrasts, so related species do not count as independent evidence. Partial r holds log10 body mass constant, because big animals live longer. Bold values have p < 0.05. Select a feature to plot it against lifespan.
