Genetic change is necessary for natural selection to take place
Genetic variation is necessary for natural selection to occur. This variation provides the raw material for differential survival and reproduction, which drives the process of natural selection. Without genetic variation, there would be no differences for natural selection to act upon.
If a population exists in an environment that changes very little, then natural selection may not provide any pressure to change. However, even under these conditions genetic driftoccurs, introducing random change within the parameters set by natural selection.
Phenotype variation is necessary for natural selection and sexual selection because it provides the raw material for evolution to act upon. Variation allows for individuals within a population to have different traits, which may offer advantages in survival, reproduction, or mate selection. Without phenotype variation, there would be no diversity for natural selection and sexual selection to operate on, thereby limiting the potential for adaptation and species diversification.
Cloning contradicts natural selection because it creates identical copies of organisms, rather than allowing for genetic diversity and variation necessary for species to evolve and adapt to changing environments. Natural selection relies on genetic variation for the process of evolution to occur, which is limited in cloned organisms.

The four principles of natural selection (variation, inheritance, differential reproduction, and adaptation) are necessary for natural selection to occur because they describe the process by which certain traits are passed on to future generations based on their ability to help individuals survive and reproduce in their environment. Variation provides the raw material for natural selection, inheritance ensures that beneficial traits can be passed down, differential reproduction leads to the accumulation of advantageous traits in a population, and adaptation allows organisms to better survive and thrive in their environment over time.
Genetic variation is one of the conditions required for Natural Selection to occur.
Adaptation does not allow for natural selection: natural selection causes adaptation.
