Why are water and carbon so essential for life? How does life use solar energy to maintain order within the cell? Why is a life without Darwinian evolution inconceivable? Where did life come from and what are the milestones in its history? How does cultural evolution complicate things when human intelligence appears?

Ultimately, how does cultural evolution affect the biology, health, and psyche of Homo sapiens? Is there life elsewhere in the Universe? If so, did it remain simple or did it evolve to the point of developing intelligence and technological culture? And, ultimately, what is intelligence?

If there are indeed other civilizations, why do they not make their presence known? Perhaps the coincidences in the case of Earth scandalously favored the emergence of intelligence? Maybe we are a rare, peculiar, perhaps even unique case? What does the future hold for life and humanity?

Where could the interaction of planetary, geological, biological, cultural, and technological evolution lead? Does overpopulation, resource depletion, climate change, and biodiversity loss threaten life, especially human life? Or just the social, political, and economic structures of humanity, as they have developed over the last millennia?

Do we all have an expiration date? This book does not require any special scientific knowledge.

The exploration of the phenomenon of life will never cease to be fascinating!
