there is variation in traits , differential reproduction and last is heredity
Evolution by natural selection.
Darwin's process of evolution was called natural selection. This process involves the survival and reproduction of individuals with advantageous traits for their environment, leading to gradual changes in a population over time.
Two key factors that determine the evolution of a species are genetic variation and natural selection. Genetic variation provides the raw material for evolutionary change, while natural selection acts on this variation by favoring individuals with traits that increase their chances of survival and reproduction.
The process of natural selection and evolution can vary in terms of the time it takes, ranging from hundreds to millions of years depending on the species and environmental factors. Evolution is a gradual process that occurs over generations as populations adapt to their changing surroundings through natural selection.
Genetic variation is important for natural selection to drive evolution because it provides the raw material for natural selection to act upon. Without genetic variation, there would be no diversity in traits for natural selection to favor or eliminate, and evolution would not be possible.
Environmental factors ARE evolution by natural selection. The immediate environment is the selector of the organisms that are differentially successful against the immediate environment.
Mutation and natural selection.

No, natural selection is believed to result in evolution.
Perhaps not, but evolution can exist without natural selection.

Natural selection directs evolution; it cannot stop or prevent it.
Natural selection is one of the mechanisms that shapes adaptation and enables evolution.

Natural selection explains the process of evolution: evolution by natural selection. It basically means that species with the highest fitness (survival rate) will live, and be selected by nature for the characteristics they possess that make them more apt to survive. Because of natural selection, evolution occurs.
