Why Echidnas Are Evolutionary Misfits

The video explores the unique characteristics of monotremes, focusing on echidnas and platypuses. It discusses their unusual traits, such as egg-laying, lack of stomachs, and long lifespans. Echidnas have a low metabolic rate and cellular resistance to aging, contributing to their longevity. Their reproductive system is also unique, with males having a four-pronged penis and females having two reproductive tracts. These adaptations highlight the evolutionary journey of monotremes, showcasing their distinct place in the animal kingdom.
