Q3 M11 Systematics Based on Evolutionary Relationships: Cladistics and Phylogeny Flashcards
It is the history of the evolution of a
species or group
Phylogeny
It is a method of classifying organisms
into groups of species called clades
Cladistics
It is a group consisting of an ancestral
organism and all its evolutionary
descendants
Clade
It is a tree diagram where each branch
point represents the splitting of two.
new groups from a common ancestor
Cladogram
It is the classification of organisms based
on traits of ancestor and descendant
Systematics
It corresponds to a common ancestor
that speciated to give rise to two (or more)
daughter taxa
Node
It represents the initial ancestor common
to all organisms within the cladogram
Root
It is the most distantly related species in
the cladogram. Functions as a point
of comparison
Outgroup
It is the species of interest, the group
of closely related organisms that
is investigated
