______ edits genetic variation created by ___ which produce new alleles, and ___ which
reshuffles the genetics, thus making sure that every individual is genetically unique.
Break down an example of natural selection…either lizards, finches, or babies (p397-399)
a. The phenotypic variation found in the population was …
b. The environmental challenge to survival was …
c. This illustrates natural selection because…
