This is used often when referring to endangered species. Endemic meaning: special, native, unique, or distinct to and also prevalent or peculiar to a specific area, locality or region. While of course mammals, are animals, warm blooded, furred, and usually nurse young with milk. This is a simplified definition, but it is only a complicated term by the way it is used. Usually it is used when discussing the populations of a specific area. You would be referencing the mammals that are unique or distinctive to say, Africa not other animals that might have been moved to, or transported to Africa. So when someone uses this term they are referring to mammals that belong, or are unique to a specific area.
Was NOT one of the changes in development and specialization that primitive mammals underwent?
Mammals have gone through many stages of development since primitive times. There is one thing that primitive mammals and the mammals of today are not able to do without the help of in vitro, and that is to live in an external environment like those environments of reptile eggs.
By definition, mammals have hair and nurse their young with milk. Some, like cetaceans, only have hair on a very small portion of their bodies or only for a portion of their lives. Some mammals have live births (placental mammals), some are born into a pouch for maturation (marsupials), and some are even hatched from eggs (monotremes).
