preevolution
Preevolution is a concept in evolutionary biology that refers to the period of time before the first known organisms on Earth. This term is used to describe the transition from a non-living, chemical-rich environment to the emergence of life. The exact timing of preevolution is uncertain, but it is generally believed to have occurred around 4.1 to 3.7 billion years ago, during the Hadean and early Archean eons.
During preevolution, the Earth's surface was subjected to intense volcanic activity, asteroid impacts, and the formation
Several hypotheses have been proposed to explain the origins of life, including the RNA world hypothesis, which
The study of preevolution is a multidisciplinary field that draws on insights from geology, chemistry, biology,
