Mammalia (taxonomy)
Mammalia is a class of animal in the phylum Chordata. What it means to be a mammal has changed many times since Carl Linnaeus first defined the class. No system is accepted by everyone. McKenna & Bell (1997) and Wilson & Reader (2005) give useful recent compendiums.[1] Many earlier ideas from Linnaeus and others are no longer used by modern taxonomists. Among these are the idea that bats are related to birds or that humans are a group outside of other living things.[2] The field has had a recent surge in interest and modification due to the results of molecular phylogenetics.
