The main difference to remember is that natural selection is a nonrandom process while genetic drift is a random process.
No, natural selection works on that genetic variation presented to it.
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.
Natural selection ' selects ' from among variations. Some organisms are better suited to their immediate environment and survive and out reproduce other organisms. All these organisms are genetically variant. That is the simple connection between natural selection and genetic variation. ( that variation coming about by mutation and recombination )
Genetic change is necessary for natural selection to take place
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
Purifying selection removes harmful genetic variations, while positive selection promotes beneficial genetic variations in natural selection.
the difference between the 2 r that natural is the best looking or tasting and artificial is fake
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
No, natural selection works on that genetic variation presented to it.
Without genetic diversity, natural selection cannot occur
Together, genetic mutation and natural selection determine in what 'direction' evolution proceeds.
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.
No, there is no genetic variation upon which natural selection can operate.
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.
