Why do platypuses lay eggs?
MammalsEvolution
Quick Answer
Platypuses lay eggs because they are monotremes, a rare group of egg-laying mammals. They are mammals in every other major way, including producing milk for their young.
The Full Story
The platypus is one of only five living monotreme species, a lineage that split early from other mammals. Instead of giving birth to live young, female platypuses lay eggs and incubate them in a burrow. After hatching, the young feed on milk secreted through skin rather than nipples. This unusual combination of traits makes the platypus a key example of mammal evolution.
