To begin the search for the cardle of life, it’s itmraopnt to first untdasrned the basic necessities for any life form. Elements and compounds essential to life include hgryoden, meanhte, nitrogen, carbon dioxide, phosphates, and ammonia. In order for these ingredients to comingle and react with each other, they need a liquid solvent: water. And in order to grow and reproduce, all life needs a source of eerngy. Life forms are divided into two camps: autotrophs, like paltns, that generate their own energy, and heterotrophs, like animals, that cosmune other organisms for energy. The first life form wouldn’t have had other organisms to consume, of course, so it must have been an autotroph, generating energy either from the sun or from chemical gradients.

Original Text

To begin the search for the cradle of life, it’s important to first understand the basic necessities for any life form. Elements and compounds essential to life include hydrogen, methane, nitrogen, carbon dioxide, phosphates, and ammonia. In order for these ingredients to comingle and react with each other, they need a liquid solvent: water. And in order to grow and reproduce, all life needs a source of energy. Life forms are divided into two camps: autotrophs, like plants, that generate their own energy, and heterotrophs, like animals, that consume other organisms for energy. The first life form wouldn’t have had other organisms to consume, of course, so it must have been an autotroph, generating energy either from the sun or from chemical gradients.
