Pain And Evolution Of Consciousness

Emotion-related inputs from the body to the brain could have generated the first traces of consciousness in our early ancestors. Being able to feel pain gives a survival advantage to animals, as they could have withdrawn from dangers and rested to promote recovery when injured or ill.

The development of awareness of body-related harms might have ultimately paved the road for the emergence of more advanced forms of conscious thought and processes, such as language, thinking, and reasoning.
