Why do humans take so long to grow up compared to other animals and how brain evolution reshaped human development and survival today?

Humans take nearly 18 to 25 years to reach full maturity, far longer than most mammals. This slow human growth is driven by brain evolution, higher cognitive demand, and long childhood learning. Human development slow brain evolution reason explains our extended dependency phase. Unlike other species, humans invest heavily in learning, language, and survival skills. It is a trade-off where slower physical maturity creates advanced thinking and long-term evolutionary success.
