Consciousness began with single-celled life, around 3.7 billion years ago (Reber). 4. Consciousness began with multicellular plants, around 850 million years ago. 5. Consciousness began when animals such as jellyfish got thousands of neurons, around 580 million years ago. 6. Consciousness began when insects and fish developed larger brains with about a million neurons (honeybees) or 10 million neurons (zebrafish) around 560 million years ago. 7. Consciousness began when animals such as birds and mammals developed much larger brains with hundreds of millions neurons, around 200 million years ago. [Thagard] 8. Consciousness began with humans, homo sapiens, around 200,000 years ago. 9. Consciousness began when human culture became advanced, around 3000 years ago (Julian Jaynes). 10.
