Phylogenetic Relationships and a Classification of the Eutherian Mammalia

摘要: It is remarkable that the enormous increase in fossil evidence, new facts from study of living mammals, and promising rise molecular studies have fact had less than usually declared effect modifying a number basic ideas on methods phylogenetic inference which been practice since beginning this century. Similarly, one finds many early (late 19th 20th century) hypotheses relationships are being “rediscovered” or remained unfalsified when evidence already known to these workers rediscovered. Growth data base increasing students addressing themselves problems nevertheless resulted an literature very sound morphological studies.
