Discuss the early atmosphere and how it could have led to the evolution of life on Earth
Earth's atmosphere formed as hot gases escaped from deep within the planet. This early atmosphere included gases such as carbon dioxide, methane, and ammonia (note that molecular oxygen was absent in the atmosphere until about 2.2 billion years ago). Experiments have shown that organic molecules necessary for life could have formed as the dissolved compounds in the atmosphere were exposed to light, heat, and electrical sparks. These energized mixtures can produce simple sugars and amino acids, proteins and nucleotides-all biologically important molecules.
