4. The fossil record provides empirical evidence for evolution because it shows that species now aren't the same as species that existed in the past and that small changes happen over time to create new species.
5. A geographic variation in the fossil record occurs when two similar organisms occupy the same time span in two different places. These organisms hold the same purpose within the overall ecology.
6. A more detailed fossil record is preferable for supporting evolution because it allows for the instances of gradual change to be recorded and placed into broader speciation events.
7. Fossils provide a great many intermediaries that connect past species with their living descendants.
8. Intraspecific competition is competition that occurs within species. This is the competition that drives natural selection.
Autotrophs are defined by their capability to create their own food source through light energy (generally), in turn creating a food source for consumers (heterotrophs).
