The results of investigations on the evolution and the systematics of the moose are presented. New data from our own research and data from the literature on morphological variability and genetics of the living moose are discussed. In addition, new data on fossil broad-fronted moose (Cervalces) and true moose (Alces) is submitted. The former genus and Libralces appear not to be direct ancestors of Alces. Based upon the new data a revision of the systematics of the moose is carried out, and questions on philogeny are considered.
