Biological Systematics

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

What is the main aim of the study of systematics?

• to calculate how many organisms there are on Earth

• to understand the evolutionary relationship of biological organisms

• to create a naming system for biological organisms

• none of the above

What do you call the system that categorizes organisms by using a naming system that includes the genus and species?

• dichotomous tree

• phylogeny

• cladistics

• binomial nomenclature

What modern method of study can trace the evolutionary relatedness of organisms by comparing the nucleotide sequences on DNA?

• phylogeny

• molecular clocks

• cladograms

• classification

Which of the following statements about taxonomy systems is false?

• Phylogeny and the Linnaean system give us the same results.

• The hierarchical classification and the Linnaean system give us the same results.

• The phylogeny system traces organisms according to their evolutionary history.

• The hierarchical classification system is the basis for taxonomic classification.

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
