1 answer
The platypus is classified as a mammal because it possesses other characteristics that define mammals such as producing milk to feed their young, having hair/fur, and having a neocortex in their brain. Its ability to lay eggs is a unique adaptation that evolved independently in platypus and echidnas, who are both classified as monotremes.
