Question:
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)?  

Responses:

B, A, C, humans

C, A, B, humans

C, B, A, humans

A, B, C, humans

B, A, C, humans

Reason: higher percent DNA shared indicates closer relation, so order from least to most related is 80% (B), 85% (A), 90% (C), then humans.
