This term describes a group of organisms that share a common ancestor, including the ancestor and all of its descendants.
Difficulty: Easy- Species
- Population
- Clade
- Genus
This substitution model distinguishes between transitions (purine-purine or pyrimidine-pyrimidine) and transversions (purine-pyrimidine) with different rates.
Difficulty: Medium- Jukes-Cantor
- Kimura 2-parameter
- F81
- GTR
This statistic, based on shared derived allele patterns (ABBA-BABA), tests for gene flow between non-sister populations.
Difficulty: Hard- D-statistic (Patterson's D)
- F-statistic
- Tajima's D
- Watterson's theta
Charles Darwin famously sketched one of these in his notebook with the words "I think" written above it, showing how species might branch from common ancestors.
Difficulty: Easy- DNA helix
- Tree of life
- Cell diagram
- Fossil record
This most complex standard nucleotide model has six substitution rate parameters and allows unequal base frequencies.
Difficulty: Medium- Kimura 2-parameter
- HKY85
- F84
- General Time Reversible
This extension of the D-statistic partitions introgression signal to specific branches, revealing which lineages exchanged genes.
Difficulty: Hard- D-statistic
- f-branch statistic
- G-PhoCS
- ABBA-BABA ratio
This is the study of the evolutionary history and relationships among individuals or groups of organisms.
Difficulty: Easy- Ecology

- Phylogenetics
This algorithm for sequence alignment introduces penalties for opening and extending gaps, reflecting the biological process of insertions and deletions.
Difficulty: Medium- Affine gap penalty
- Linear gap penalty
- Constant gap penalty
- Progressive alignment
