Why prototherians are unfinished mammals?

Prototherians, such as the platypus and echidna, are considered "unfinished" mammals because they exhibit both reptilian and mammalian characteristics. They lay eggs like reptiles, but also produce milk for their young like mammals. These unique features suggest that prototherians represent an ancient stage in mammalian evolution before the development of more distinct mammalian traits.
