Newborn human babies with lesser body weight are prone to infections. Heavier babies are difficult to deliver through the narrow pelvic passage of human mothers and may not survive. Babies with normal body weight have a better chance of survival and can be delivered normally. What kind of selection is exhibited in this case?

Explanation:

One of the most famous examples of a species with stabilizing selection is humans. If the birth weight of a human is too low, it will have difficulty surviving after birth. On the other hand, a baby weighing too much would create complications for both the mother and the child. In these scenarios, the middle ranges are the optimal birth rate.
