Clay Minerals as Life’s Cradle
Some researchers propose that clay minerals played a pivotal role in the origins of life by serving as natural laboratories for early chemistry. The surfaces of certain clays can attract, concentrate, and organize organic molecules, thereby increasing the likelihood of complex reactions. Laboratory experiments have demonstrated that clay can facilitate the formation of RNA-like chains and other crucial biomolecules. This theory highlights the potential for humble minerals to play a vital role in the earliest stages of life.
