Taxonomy of Animals

A character derived from common ancestry

Applies to both sexual and asexual species,Adds the evolutionary time dimension, and Addresses hybrids

Believed species were distinct, unchanging entities divinely created

Derived characteristic unique to a clade and not found in the ancestor

taxa closely related to ingroup but not included – used for comparison

the taxa being studied

the science of biological diversity and its evolutionary history

A character state in a most recent common ancestor is

ancestral lineage and all descendents

A grouping of organisms distinct from other groupings and in which there is a parental pattern of ancestry and descent

ancestor for every taxon on cladogram

includes most recent common ancestor but not all descendents

speciation event; represents common ancestor

the organisms whose phylogeny is shown on tree

Who first classified organisms based on structural similarities

DNA barcoding is a technique used for identifying species using standard gene sequences present in all animals.

Classification focuses on traits, whereas systematization focuses on using traits to confirm a hypothesis

A single specimen that formally bears name of species

the science of naming, describing, and classifying animals

does not include most recent common ancestor of all members in group

Specifies that populations of a species have genetic or demographic cohesion; applies sexually or asexually

history of a taxon; ancestral lineage

Who designed out current classification system?

includes most recent common ancestor and all descendents; a clade

the scientific study of the evolutionary history of a taxonomic group

There are 32 recognized phyla in the animal kingdom and each is monophyletic

Extant means no-longer living.
