| 5379698923 | Continental drift | The idea that all land on Earth was once one great mass but then broke up into continents and drifted into their places now | 1 | |
| 5379698924 | Pangaea | The name of the original supercontinent | 2 | |
| 5379698925 | Plate tectonics | Describes the forces involved in the movement of Earth's plates tectonics and the geologic processes that result | 3 | |
| 5379698926 | Phylogeny | The evolutionary history of a group of organisms | 4 | |
| 5379698927 | Convergent evolution | Species from different evolutionary branches may come to resemble one another if they live in very similar environments | 5 | |
| 5379698928 | Analogy | Similarity due to convergence (aka analogous structures) | 6 | |
| 5379698929 | Binomial | The two-part Latin name assigned to organism, created by Linnaeus | 7 | |
| 5379698930 | Genus | The first part of the binomial which is the species the organism belongs to | 8 | |
| 5379698931 | Classification of organisms | Domain → Kingdom → Phylum → Class → Order → Family → Genus → Species | 9 | |
| 5379698932 | Phylogenetic trees | What biologists traditionally use to depict hypotheses about the evolutionary relationships/history of species | 10 | |
| 5379698933 | Cladistics | The identification of clades | 11 | |
| 5379698934 | Clades | Evolutionary branches that consist of an ancestral species and all its descendants | 12 | |
| 5379698935 | Cladogram | A diagram depicting the pattern of shared characteristics | 13 | |
| 5379698936 | Ingroup | Is the group of taxa actually being analyzed | 14 | |
| 5379698937 | Outgroup | Closely related to ingroup but not a part of it | 15 | |
| 5379698938 | Parsimony | The quest for the simplest (and thus most likely) explanation for observed phenomena | 16 | |
| 5379698939 | Molecular systematics | Comparing nucleic acids or other molecules to infer relatedness | 17 | |
| 5379698940 | Molecular clock | To show that a gene has a reliable average rate of change, this is calibrated in actual time by graphing the nucleotide differences against the dates of evolutionary branch points | 18 | |
| 5379698941 | Five-kingdom system | Whittaker argued for five kingdoms: Mnera, Protista, Plantae, Fungi, Animalia instead of original three kindgom scene | 19 |
