Asian elephants are more closely related to mammoths because they share more nodes and branches on the phylogenetic chart. This relationship suggests a closer evolutionary ancestry. Mastodons and Paleomastodons are not the same species. There are branches from Paleomastodon and Mammuts that suggest speciation occurred. Mammuts also have common evolutionary ancestors that Paleomastodons do not have.
