What do lightning and life have in common? Getty Life would emerge on any sunny, wet rocky planet. Michael Russell, California Institute of Technology. Close window Published online: 14 November 2006; | doi:10.1038/news061113-9 Was life on Earth inevitable? Life may be the ultimate in planetary stress relief, a new theory claims. Philip Ball The appearance of life on Earth seems to face so many obstacles — sourcing the right ingredients, for example, and arranging them into living things (while being bombarded by meteorites) — that scientists often feel forced to regard it as almost miraculous. Now two US researchers suggest that, on the contrary, it may have been inevitable. They argue that life was the necessary consequence of available energy built up by geological processes on the early Earth. Life sprang from this environment, they say, in the same way that lightning relieves the accumulation of electrical charge in thunderclouds. In other words, say biologist Harold Morowitz of George Mason University in Fairfax, Virginia, and physicist Eric Smith of New Mexico's Santa Fe Institute, the geological environment "forced life into existence".
