Biological Evolution and Classification

Essential Question – Bell Ringer

How can a biologist tell if two organisms belong to the same kingdom?

Organisms that belong to the same kingdom share structural and physiological characteristics that enable scientists to place them in distinct groups.

Hierarchical Classification

I need to remember……..

• I need to remember . . .• Scientists use internal and external characteristics to

classify organisms into similar groups.• Within the hierarchical classification system, the domain

is the group that includes the greatest number of organisms and exhibits the greatest diversity of organisms.

• The species is the group that includes the fewest number of organisms and exhibits the least diversity of organisms.

• Taxonomy is a branching classification system that provides a standardized method for grouping organisms.

Post Review Question

• Which of the following contain all the kingdoms with eukaryotic organisms?

A.Archae and Bacteria

B.Animalia, Plantae, and Bacteria

C.Animalia, Plantae, and Protista

D.Animalia, Plantae, Protista, and Fungi

Post Review Question

• A team of scientists collected a unicellular, prokaryotic organism that lived in a volcanic hot spring and had lipids in its cell membrane that were not found in any other group of organisms. The scientists most likely classified the organism into which of the following kingdoms?

A. Plantae

B.Animalia

C.Archaebacteria

D.Fungi
