This question is about mammals. a) What is the one defining characteristic that determines a mammal? b) Compare and contrast the three types of mammals with respect to fetal development and birth: the monotremes (such as the platypus), the marsupials (such as kangaroos), and the placentals (such as humans or dogs). That is, where does most of the early development occur, how is the young mammal introduced to the world, and how does the young obtain nourishment once introduced to the world?
