The biggest evidence of natural selection is the progression in the morphology of fossil over time. Some of the fossils are of extinct species. This evidence point to the fact that species evolved from other species, gradually evolving new physical features. This is related to the environment in which they lived in since their morphologies allowed them to be well adapted for their environments.

Answer:
Independent variable: varying amounts of light
Dependent variable: plant growth
Explanation:
The variable, which are factors that can be altered, in an experiment can either be independent or dependent. An independent variable is one in which the experimenter manipulates or controls in order to bring about an outcome. For this experiment conducted by Rachel, the independent variable is the VARYING AMOUNT OF LIGHTS.
The dependent variable is the variable that responds to changes of the independent variable. In other words, the dependent variable is the outcome of manipulating the independent variable. Hence, the dependent variable is dependent on the independent variable. For Rachel's experiment, the PLANT GROWTH is the dependent variable because it is what responds to changes in amount of light (independent variable).
