Evolution proceeds unevenly across the tree of life, with some lineages accumulating diversity more rapidly than others. Explaining this disparity is challenging as similar evolutionary triggers often do not result in analogous shifts tree, and may reflect different triggers. We used a combination approaches to directly consider such context-dependency untangle complex network processes that shape macroevolutionary dynamics, focusing on Pleurodonta, diverse radiation lizards. Our approach shows lineage-wide signatures are lost when conditioned sublineages: while viviparity appears accelerate diversification, its effect size overestimated by association Andean mountains. Conversely, signals erode at broader phylogenetic scales emerge shallower ones. Mountains, general, affect speciation rates; rather, occurrence mountains specifically promotes diversification. Likewise, evolution larger sizes catalyzes diversification rates, but only within certain ecological geographical settings. caution conventional methods fitting models entire trees mistakenly assign heterogeneity specific factors despite evidence against their plausibility. study takes significant stride toward disentangling confounding identifying plausible sources opportunities large radiations.
