The inherent differences between Monster Beasts and the Human Race are fundamental. Even though both rely on absorbing Spiritual Power from the world to become stronger, their evolutionary paths have essential differences.
Human beings are naturally weak, with newborns at risk if removed from their parents' care. Even matured human bodies don't stand out in comparison to beasts in physical capabilities without deliberate martial arts training. Even if you are a child of a saint, neglecting martial training would still leave you a fragile commoner.
But, Monster Beasts are different. The stronger the beast, the stronger the offspring it produces. Some powerful beasts like dragons can hunt small animals when they are still young to become self-sufficient. The powerfulness of a Monster Beast is directly related to its race.
