Not now! Because monkeys evolved into adults under certain environmental conditions! Or the key point of evolution: "natural selection, survival of the fittest"! At that time (millions of years ago), in order to survive in the ever-changing natural environment, monkeys had to undergo an evolution to adapt to environmental changes, gradually developed into upright walking, and finally evolved into modern people. The environmental conditions now are completely different from those of millions of years ago! Under the current environmental conditions, monkeys are of course still evolving, but it is unlikely that they will embark on the same evolutionary path as their ancestors!
