From: From the scala naturae to the symbiogenetic and dynamic tree of life
The tree-like "Synade-model of macroevolution", taking into account all five Kingdoms of life on Earth. According to this theory, symbiogenesis (primary and secondary endosymbiotic events), (directional) natural selection, and the (internal heat-driven) dynamic Earth were and still are key drivers of macroevolution on our "planet of the bacteria" [adapted and modified from ref. 62].
