Mammalian Pregnancy: The Placental, the Pouch, and the Peculiar
There are three main methods found in Class Mammalia to reproduce and create the next generation. These methods divide mammals into three groups: placental, marsupial, and monotreme. Most mammals, humans included, develop their young with the use of a temporary organ called the placenta. Marsupials, while still producing a placenta, utilize a different organ, the pouch, to facilitate a large portion of the development. For monotremes, reproduction involves laying a soft-shelled egg. Even throughout these diverse methods of development, there are many similarities and differences which highlights the uniqueness of each species and the connectiveness across the Earth.
