The platypus, a native of eastern Australia, is a puzzling creature with features from birds, mammals, and reptiles. Male ...
In echidnas and platypuses, evolution duplicated the gene, parked the copy on a Y chromosome, and rewired its control panel to switch on early in male gonads. Sex starts outside the cell’s nucleus ...
What's more, just how they do it has been a mystery. Until now. In a recent study published in Genome Biology, our research team has found strong evidence that monotreme sex comes down to a single ...

The platypus holds immense scientific significance as a “living fossil” that provides unique insights into mammalian evolution. When the first platypus specimen reached England in 1798, it caused such ...
Between backward-facing-feet, nipple-less milk secretion and egg-laying, platypuses and echidnas are some of the strangest ...
To shed more light on echidna evolution, Hand and her colleagues reexamined a humerus (upper forelimb bone) from the extinct monotreme Kryoryctes cadburyi, which lived in what is now southern ...
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.
