Unit 1 Species Classification

The three domains of life

• Protists

• Archaea

• Bacteria

• Eukaryotes

• Prokaryotes

Which domain are eukarya most closely related to?

• Bacteria

• Archaea

• Fungi

• Animalia

• Prokaryotes

Study of the evolutionary relationship between species through the construction of phylogenetic trees which compare molecular and morphological features.

A form of systematics which involves the classification of species in hierarchical categories

A new species is discovered and classified into the genus Canis and the species lupus. This is an example of

• Taxonomy

• Phylogenetics

• Evolution

• Binomial nomenclature

Which of the following represents a paraphyletic group?

• 
• 
• A group which includes a common ancestor but not all of the descendants

• 
• A group which includes a common ancestor and all of the descendants
