Mutation, genetic drift and gene flow can all drive evolution to a degree and the last two, drift and flow, are especially powerful in small populations. But, the driver of adaptive change in all populations of organisms is natural selection.
The process of things changing gradually over time is known as evolution.
Natural selection is the most significant factor in the evolution of an organism. It drives the process by selecting for traits that best suit an organism to its environment, leading to the accumulation of advantageous genetic variations over time.
Competition is important in evolution because it drives the process of natural selection. Organisms with traits that provide an advantage in competing for resources are more likely to survive and reproduce, passing on those advantageous traits to their offspring. This leads to the gradual evolution of species over time.
The given name for genetic changes in living things over time is evolution. This process drives the diversity and adaptation of species in response to environmental conditions.
Evolution is the process by which species change over time through natural selection. Theories of evolution, such as Darwin's theory of evolution by natural selection, are explanations for how evolution occurs and the mechanisms driving it. In essence, evolution is the phenomenon, while theories of evolution are the explanations for how it happens.

Adaptation is a key mechanism in evolution, as it allows organisms to better survive and reproduce in their environment. Individuals with advantageous traits that enhance their survival have a higher chance of passing those traits to future generations, leading to a shift in the gene pool over time. This process ultimately drives the diversity of life we see today.
Evolution is a process; it doesn't have a color.
Genetic variation drives evolution by providing the raw material for natural selection to act upon, allowing organisms to adapt to changing environments. Environmental factors can influence which traits are favored, shaping the direction of evolution. Together, genetic variation and environmental factors contribute to the diversity of life on Earth through the process of evolution.
The basis for evolution is the process of natural selection, which drives the gradual change in the genetic makeup of a species over time. Individuals with advantageous traits are more likely to survive and reproduce, passing on their genes to the next generation. This leads to the accumulation of beneficial traits in a population over generations.
Some examples of natural selection questions include: How does the environment influence the survival of certain traits in a population? How do changes in a species' habitat affect its evolution over time? How do different adaptations help organisms thrive in their specific environments? By studying these questions, scientists can gain insights into how natural selection drives the process of evolution.
