Question

New forms of life have arisen through the modification of existing structures or existing developmental genes. This is known as evolutionary adaptation, where organisms adapt to changing environmental conditions over time through genetic changes, such as mutations or gene expression modifications. Sexual selection and the availability of resources after other species go extinct can also play a role, but they are not the primary driving force behind the creation of new forms of life. The idea of a "process of species living in variable environments with the end goal of mutating and evolving" is not entirely accurate, as evolution is not a goal or purposeful process, but rather a result of natural selection acting on genetic variation.
