The purpose of this article was to uncover the evolutionary lineage of the giant short-faced bears, also known as Tremarctinae which are found in North and South America. The hypothesis for the article was that although the Artodus, which are the North American short-faced bears, and Arctotherium, which are the South American short-faced bears have the same survival traits they evolved autonomously of each other. This means that the two species have deviated from each other, but still evolve the same traits to sustain themselves or fill their vocation, which is called convergent evolution. Ancient mitochondrial DNA was used to trace the lineages from the fossilized bones and the DNA sequences were analyzed to distinguish how the bear's molecular
