Worked practice questions

Structures that look similar but do not share a developmental and evolutionary origin are called:

  1. Derived structures
  2. Ancestral structures
  3. Analogous structures
  4. Homologous structures
Show answer and solution

Correct answer: C. Analogous structures

1. Similarity of appearance is not by itself evidence of relatedness. 2. Homologous structures overlap both morphologically and genetically. 3. Structures that resemble each other without that shared basis are called analogous structures. 4. Only homologous structures support a claim of common ancestry. _Source: OpenStax Biology for AP(R) Courses (CC BY 4.0), Ch 20 'Phylogenies and the History of Life', sections 20.1-20.3_

A group containing an ancestor and all of its descendants forms a clade, also called a:

  1. Polyphyletic group
  2. Paraphyletic group
  3. Analogous group
  4. Monophyletic group
Show answer and solution

Correct answer: D. Monophyletic group

1. Clades are defined by completeness of descent. 2. Organisms sharing amniotic eggs make a single clade. 3. Such a clade is also called a monophyletic group. 4. Leaving out some descendants would break the group's monophyly. _Source: OpenStax Biology for AP(R) Courses (CC BY 4.0), Ch 20 'Phylogenies and the History of Life', sections 20.1-20.3_

Taxonomy is described as a tool whose purpose is to:

  1. Organize millions of organisms
  2. Prove evolution occurred
  3. Measure genetic distance
  4. Predict future species
Show answer and solution

Correct answer: A. Organize millions of organisms

1. A classification system is a practical device as well as a scientific claim. 2. Taxonomy is a tool to organize the millions of organisms on Earth. 3. The comparison drawn is to how items in a grocery store are organised into departments. 4. The tree of relationships is what carries the evolutionary claim. _Source: OpenStax Biology for AP(R) Courses (CC BY 4.0), Ch 20 'Phylogenies and the History of Life', sections 20.1-20.3_
