This Animal Lays Eggs AND Has Live Young

The video explores the fascinating reproductive strategies of lizards and snakes, focusing on a unique skink that gives birth both through eggs and live birth in the same clutch. It discusses the evolutionary transition from egg laying to live birth, highlighting the pros and cons of each method. The video delves into the diversity of reproductive strategies among squamates, including egg retention and yolk-fed young. By studying these reptiles, researchers gain insights into the evolutionary processes that shaped mammalian reproduction, including the development of the placenta.
