is the process of evolution based on?

ossils
atural selection
enetic mutation
nvironmental adaptation

The correct answer is: atural selection

Natural selection is the central process of evolution. It is driven by the survival of organisms with advantageous traits in their environment. Fossils, genetic mutations, and environmental adaptation are all related to evolution, but they are not the central driving force. Fossils can provide evidence for past evolutionary processes, genetic mutations can lead to new traits, and environmental adaptation allows organisms to better survive in their habitats. However, natural selection is the main mechanism that drives evolution forward.
