How are marsupials adapted to live in the Southern Hemisphere? New AI may pass the famed Turing test. The platypus is able to hold its breath for up to two minutes underwater when diving for food, and because of this, may make hundreds of dives in order to find enough food for a single feeding.

The first occurrence in the fossil record of a platypus-like monotreme is from about 110 million years ago, in the early Cretaceous Period, when Australia was still connected to South America by Antarctica. Little fossil evidence of monotremes exists, but scientists believe that before evolving to deliver live young, most mammals laid eggs.
