This booklet summarizes significant facets of the evolution of South American metatherians, together with their epistemologic, phylogenetic, biogeographic, faunal, tectonic, paleoclimatic, and metabolic contexts. a short evaluation of the evolution of every significant South American lineage ("Ameridelphia", Sparassodonta, Didelphimorphia, Paucituberculata, Microbiotheria, and Polydolopimorphia) is provided. It is argued that because of physiological constraints, metatherian evolution heavily the stipulations imposed via worldwide temperatures. mostly phrases, throughout the Paleocene and the early Eocene a number of radiations of metatherian lineages happened, with many adaptive varieties exploiting insectivorous, frugivorous, and omnivorous adaptive zones. In flip, a mix of generalized and really good forms, the latter customarily exploiting carnivorous and granivorous-folivorous adaptive zones, characterised the second one 1/2 the Cenozoic. In either classes, weather was once the serious motive force in their radiation and turnovers.
