A new study suggests the platypus and echidna — the only egg-laying mammals — had a water-dwelling ancestor. The finding could upend what’s known of their evolution.

Motorcycles aren’t normally welcome on the golf course, but a fairway-friendly electric two-wheeler is now headed for ...

The platypus was ultimately placed into a new order called Monotremata, alongside the four living species of echidna. Monotremes are, notably, egg-laying mammals that produce milk for their young. The ...

University of Adelaide researchers discovered monotremes use a completely different sex determination system than other ...

Platypuses only live naturally in eastern Australia and Tasmania, and there are an estimated 300,000 left in the world. In dammed rivers, they are divided into small, genetically distinct groups ...

Outliers among mammals, monotremes lay eggs instead of giving birth to live young. Only two types of monotremes, the platypus and echidna, still exist, but more monotreme species were around about ...

Platypuses spend a good portion of their lives in the water. When that water dries up, not only do they need to find new ...

For decades, scientists have known that platypuses and echidnas – Australia’s unique egg-laying mammals – have another developmental quirk: they don’t use the same genetic toolkit as other mammals to ...
