Question

which example best demonstrates the importance of having knowledge of evolutionary relationships?
○ illustration of a plant leaf
○ organ transplantation between species
○ blood donation from a human to a human
○ dna sequence of an insect

Explanation:

To determine the example showing the importance of evolutionary relationships knowledge, we analyze each option:

• "illustration of a plant leaf" relates to plant anatomy, not evolution.
• "blood donation from a human to a human" is about human biology/medicine, not evolution.
• "organ transplantation between species" requires understanding evolutionary relatedness (e.g., immune compatibility, genetic similarities) to assess success, as closer evolutionary relationships mean more similar physiology.
• "DNA sequence of an insect" is about genetics, not directly about the importance of evolutionary relationships in a practical context like transplantation.

So the best example is organ transplantation between species as it relies on knowing evolutionary relationships for compatibility.

Answer:

C. organ transplantation between species
