内容説明
What were the factors that spawned life on Earth? And how would life have evolved if any of those elements were changed? If the moon were closer to the Earth than it is, tides would be more extreme; the Earth would rotate more slowly, creating longer days. Conversely, if there was no moon, the Earth would rotate more than five times faster than it does, and tides would be much lower. On a moonless Earth, the atmosphere would probably be of the same thickness and makeup of Venus, where there is no life. And what if Earth had two moons? Or if the Earth were less dense, or if the solar system were younger, or located closer to the edge of the universe? What would life on Earth be like? In this book, Neil Comins analyzes how differences would affect the plant, animal and human life on planet Earth. His examination should help readers gain an understanding of the Earth's place in the solar system, and of just how fragile that place is.
