Evolution of brains, consciousness and suffering

The article explains that consciousness evolved gradually, not suddenly, beginning with simple life forms.
Early organisms developed a basic sense of self vs environment, forming the roots of subjectivity.
With multicellular life, nervous systems enabled faster communication and reflex-based behavior.
Consciousness likely emerged during the Cambrian explosion, driven by predator-prey adaptation and improved sensory systems like vision.
Over time, higher functions such as memory, self-awareness, and reflection developed.
Ultimately, consciousness provides adaptive advantages by integrating sensory data, enabling prediction, flexible behavior, and better survival decisions.
