Echidnas: Secret Aquatic Pasts?!

Plot twist: echidnas might actually be water babies at heart! 🦔💦 A 108-million-year-old bone just revealed that both echidnas and platypuses probably evolved from semi-aquatic ancestors, not land-dwellers like we thought. Turns out, that weird little monotreme humerus bone has more in common with platypuses than anyone expected. Basically, echidnas could be ex-swimmers who ditched the water for land life.
