The life cycle of placental mammals begins with the fertilization of an egg, leading to the development of an embryo within the mother's uterus. The embryo receives nutrients and oxygen through the placenta, allowing for extended gestation periods. After birth, the young are nourished with milk produced by the mother, promoting further growth and development. The life cycle continues as the offspring mature into adulthood, capable of reproduction, thus completing the cycle.
Placentals are mammals. All mammals are vertebrates which means they do have backbones.
