This publication summarizes significant points 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 as a result of physiological constraints, metatherian evolution heavily the stipulations imposed by means of international temperatures. ordinarily phrases, in the course of 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 expert kinds, the latter commonly exploiting carnivorous and granivorous-folivorous adaptive zones, characterised the second one half the Cenozoic. In either sessions, weather used to be the severe motive force in their radiation and turnovers.
