Chapter 14.6, Problem 4MC
Summary Introduction
To enlist:
The types of evidences do biologist use in cladistics analysis.
Concept introduction:
Cladistics approach is a way to biological classification in which organisms are categorized in groups based on the most recent common ancestor. This approach is based on evolution.

Students have asked these similar questions
how can a scientist use dna taken from three different organisms to construct a cladogram?
A scientist is attempting to build a cladogram that shows the evolutionary closeness of three organisms in relation to humans. After doing DNA analysis, they determine that the organisms share the following percentages of DNA:
Organism A and humans share 85% of their DNA.
Organism B and humans share 80% of their DNA.
Organism C and humans share 90% of their DNA.
Based on this information, which order should they go on the cladogram (from least related to most related)?
Does the use of DNA sequences in the study of evolutionary relationships mean that other characteristics are unimportant in such studies? Discuss what other forms of evidence you may still want to use, along with when and why those other forms of evidence would be especially helpful.
