Extended Data Fig. 5: Depths of non-co-diversifying bacterial clades and ages of host clades.
From: Widespread extinctions of co-diversified primate gut bacterial symbionts from humans
Scatter plot and regression line show the association between the depths of strongly non-co-diversifying bacterial clades (r < 0) based on protein divergence of bac120 single-copy core genes and the known ages of their corresponding host clades based on timetree.org (df = 53; t = 0.86; unadjusted p-value = 0.393). Each point corresponds to a bacterial clade. The non-codiversifying clades were derived from host species spanning the same epochs as in Extended Data Fig. 3. Bands represent 99% confidence intervals, centre line represents best-fit regression, and p-value represents result of two-sided Student’s t-tests. In contrast to results displayed in Extended Data Fig. 3 based on co-diversifying clade depths, non-co-diversifying clade depths were not significantly positively associated with known ages of the corresponding host clades.
