A plant, a tree, a shrub: everything in the DNA. DNA creates cells and growth and specialisation. The diversification of the cell is its survival and way of life.
The insect: Micro-brain, DNA and ganglia. The ganglia control the body functions and movement. The micro-brain handles the sensory information not unlike a logic controller used in industrial machines. The body moves and senses. A robot, nothing more, nothing less.
A vertebrate. A brain. A central brain needs so much energy. No wonder we identify with it, and not with Source.
