Definitions:

Incomplete Lineage Sorting

Occurs when a genetic polymorphism persists through several speciation events. When fixation of alternative alleles eventually occurs in the descendent species, the pattern of retention of alleles may yield a gene tree that differs from the true phylogeny of the species.

Genetic Hitchhiking

Genetic hitchhiking occurs when an allele increases in frequency because it is physically linked to a positively selected allele at a nearby locus.

Molecular Phylogenetic Studies

Research that uses the molecular sequences of DNA, RNA, or proteins to infer the evolutionary relationships between different species or organisms.

Lobe-Finned Fish

A group of fish characterized by fleshy, lobed, paired fins, which are precursors of the limbs of land-living vertebrates.
