   Where did life come from?

   • Some hints come from the oldest zircons, highly durable minerals that formed in magma. Scientists have found traces of a form of carbon—an important element in living organisms— in one such 4.1 billion-year-old zircon. However, it does not provide enough evidence to prove life’s existence at that early date. Where did life on Earth begin?

   Did life start elsewhere in the universe?

   • A minority of scientists argue that life must have begun elsewhere in the universe and been carried to Earth, an idea known as “ panspermia ”. However, most researchers think this falls foul of Occam’s razor, especially as no extraterrestrial life has been found. The thorniest question is the mechanism by which life began.

   Why did Earth's First life form in a plume?

   • The microorganisms that live near such plumes have led some scientists to suggest them as the birthplaces of Earth’s first life forms. Organic molecules may also have formed in certain types of clay minerals that could have offered favorable conditions for protection and preservation.
