    1. unless some kind of evolutionary force is acting upon the population, neither the allele nor the genotypic frequencies would change.

      I feel like this contradicts genetic drift, as allele frequencies can change with no apparent advantage or disadvantage just due to mutation.

    2. The allele frequency within a given population can change depending on environmental factors; therefore, certain alleles become more widespread than others during the process of natural selection.

      How do you measure allele frequency in a population?

    1. The theory does not try to explain the origin of life. The theory of evolution explains how populations change over time and how life diversifies the origin of species.

      I really like this section, I've never thought of it this way before. I had always understood evolution and had it explained to me as an explanation of life's origins by going farther and farther back. This was very transparent.

    2. In science, a “theory” is understood to be a body of thoroughly tested and verified explanations for a set of observations of the natural world.

      If theories are thoroughly tested and widely accepted as fact why don't we call them laws? What is the difference between a law and a theory?
