Phylogeny Revision


While exploring a rainforest canopy, a field researcher discovers four new insect species. The researcher makes a preliminary phylogeny, labeling the Species A, B, C, and D, based on anatomical comparisons.

After returning to the lab, they do an amino acid comparison of a protein. They revise the original phylogeny based on the new protein-based​ evidence.

Which of the following would explain the differences in the proposed phylogenies?


Species B and C both have a green carapace and eyestalks.

Species D has eye stalks, but no carapace.
