If humans evolved backward, reverting to earlier stages of our evolutionary history, we would see profound changes in our physiology, behavior, and societal structures.
Initially, the loss of advanced cognitive abilities would lead to the breakdown of complex communication, technological advancements, and social organizations.
Over time, physical transformations would occur, potentially resulting in a more robust but less specialized anatomy, resembling our primate ancestors.
This devolution would impact our survival strategies, shifting from reliance on tools and cooperative societies to more instinct-driven behaviors and basic survival mechanisms. The intricate fabric of human culture, art, and science would unravel, giving way to a simpler existence dominated by the immediate need to adapt to a changing environment.
