Ginasavagex Cambro [extra - Quality]

A total of (Table S1) were sampled from three iconic Lagerstätten:

A combined morphological‑molecular matrix (where possible) was assembled (see Supplementary Data). Bayesian inference was performed in with a Mk + Γ model, running 10⁷ generations and sampling every 1,000 generations. Convergence diagnostics (ESS > 200) were assessed with Tracer 1.7. ginasavagex cambro

The repeated emergence of grasping structures across disparate clades highlights imposed by the Cambrian ecosystem. This supports a view of the Cambrian explosion as not merely a taxonomic event but a functional re‑organization of marine food webs (Budd & Mann 2019). A total of (Table S1) were sampled from

GAMs revealed a between marine oxygen levels (pO₂) and morphological disparity (edf = 3.2, p < 0.001). Peaks in disparity align temporally with documented oxygenation excursions (Meyer et al. 2021), supporting the hypothesis that increased oxygen availability facilitated anatomical innovation.
