Cladograms and Taxonomy

Which of the following shows the correct order of the levels of classification from largest to smallest?

• Species - Class- Order - Kingdom - Genus - Family - Phylum

• Species - Genus - Family - Order - Class - Phylum - Kingdom

• Kingdom - Phylum - Class- Order - Family - Genus - Species

• None of the above

The science of grouping and naming organisms.

• Classification

• Binomial Nomenclature

• Dichotomous Key

• Taxonomy

Which category would contain the most organisms?

• Phylum

• Species

• Kingdom

• Animalia

We know that Canis lupus is a gray wolf and Canis latrans is a coyote. What level of classification do they have in common?

• the Species name is the same

• They are both Cats

• the Genus name is the same

• They are Prokaryotes

A biologist sequences a gene shared by five different species. The percentage of sequence similarity for four different gene segments, A, B, C, and D, are shown in the table. Using the data in the table, move the species labels into the blank boxes of the cladogram to show the relationships among the species.

In a cladogram -

• the most ancient organisms, called the origin, are found at the very base of the tree diagram.

• the closer the branch point is to an organism, the more distantly related those organisms are

• neither A nor B are true

• both A and B are true

According to paragraphs 6 and 7, we know that the phylogeny system — 

• groups organisms together into units called clades

• has phylogenetic or evolutionary trees and cladograms that demonstrate the same pattern

• traces the relatedness of organisms according to their evolutionary history

• all of the above are true
