Chemical evolution is thought to have caused the first cells to spontaneously generate over a very long period of time.
Abiogenesis
Chemical evolution is thought to have caused the first cells to spontaneously generate over a very long period of time.
The theory of abiogenesis (aka biopoiesis) suggests that amino acids, which form naturally under the proper chemical conditions, could have joined to form self-replicating chains such as RNA. Once formed, these molecules could have evolved into more complex forms such as DNA.
The process of a species changing over a long period of time is known as a metamorphosis.
