Temperature dependence of evolutionary diversification: differences between two contrasting model taxa support the metabolic theory of ecology

Biodiversity patterns are largely determined by variation of diversification rates across clades and geographic regions. Although there are multiple reasons for this variation, it has been hypothesized that metabolic rate is the crucial driver of diversification of evolutionary lineages. According to the metabolic theory of ecology ( MTE ), metabolic rate – and consequently speciation – is driven mainly by body size and environmental...
