Phylogeny
|
the evolutionary history of a species or group of species.
|
|
|
Taxon
|
Named taxonomic unit at any level of the hierarchy
|
|
|
The placement of species into orders, classes, and so on, does not necessarily reflect evolutionary history, T or F.
|
True.
|
|
|
Phylogenic trees do not necessarily tell us about their evolutionary relationships, T or F.?
|
True.
|
|
|
Phylocode
|
Recent classification that proposes organization entirely on evolutionary relationships.
|
|
|
Polytomy
|
A branch point from which more than two descendent groups emerge. This indicates the evolutionary relationships among the descendant taxa are not yet clear.
|
|
|
No assumptions should be made about when particular species evolved or how much genetic change occurred in each evolutionary lineage, T or F.
|
T
|
|
|
We can assume that a taxon on a phylogentic tree evolved from the taxon next to it, T or F.
|
F
