The changes that have occurred in living organisms over the past four billion years are primarily due to the interaction of genetic and environmental changes. This process is known as evolution, which occurs through natural selection, mutation, migration, and genetic drift. Environmental changes such as changes in climate or geological events can influence evolutionary processes, whereas genetic changes can be influenced by natural selection, random mutation, or gene flow between populations. Therefore, option D is the best choice.
