How can an egg form a fully formed animal outside the womb but we can’t do the same with a premature human infant?
In: 5
Because the egg contains all of the ingredients closed inside it (nutrition, really) that it needs, whereas a premature baby before certain amount of gestation isn’t developed enough to survive because they basically get their nutrition via “mainline connection” directly to moms body and receive the nutrition as mom produces it. The egg has a nutrition “bank” inside it ready to go for the full period of development. Some preemies can live and continue to grow and develop outside because their organs (stomach and lungs) have developed enough to enable them to process oxygen or formula and keep receiving nutrition to complete development outside the womb.
