Gene
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules
Phylogenetic tree
is a diagram that depicts the lines of evolutionary descent of different species, organisms, or genes from a common ancestor
Taxonomy
taxonomy is the scientific study of naming, defining and classifying groups of biological organisms
Ancestral lineage
is a temporal series of populations, organisms, cells, or genes connected by a continuous line of descent from ancestor to descendant.
-
Divergence event
is the process in which two or more populations of an ancestral species accumulate independent genetic changes (mutations) through time, often leading to reproductive isolation
Internal Node
at the points where more than one branch meet and represent the (usually inferred) ancestral sequences
Common ancestor
An ancestor that two or more descendants have in common. ... The theory of evolution states that all life on earth has a common ancestor.
