Researchers replicated early Earth conditions and found that cloud-to-ground lightning may have produced essential molecules for life.
Harvard researchers team established that cloud-to-ground lightning may have contributed to creating the essential building blocks for life on Earth.For a long, scientists have been figuring out what could have helped generate the building blocks needed for life on Earth to arise. Many believe that asteroids or comets must have built these blocks.
As scientists have studied these theories, they have found them less likely. For example, collisions with objects in space became rare after the Earth formed, and lightning strikes between clouds are inefficient in generating useful materials. Carbon, for example, was converted to carbon monoxide and formic acid, and nitrogen was converted to nitrite, nitrate, and ammonium.
Life on Earth began approximately 3.7 billion years ago, yet the molecular mechanisms of its emergence remain largely unknown.
