Life On Earth May Have Begun With Amino Acids
According to another theory, life on Earth may not have begun with RNA but rather with amino acids able to fold into proteins in a high salt environment. Ask scientists how life on Earth began and they’ll tell you some version of this story: Around 3.5 to 3.9 billion years ago, RNA molecules emerged in a warm environment, and everything grew from there. Since all living cells contain RNA, the theory makes some sense.
