Question

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?

• A. Species B and C both have a green carapace and eyestalks.
• B. Species B does not have eye stalks or a green carapace.
• C. Species D developed a green carapace and eyestalks independently.
• D. Species D has eye stalks, but no carapace.

Answer 1

The correct option is A Species B and C both have a green carapace and eyestalks.

In the morphology based cladogram A is an outgroup, B has Green carapace, both C and D have carapace and eyeballs

In the protein comparison cladogram A is an outgroup, and species D is branched from A, so here A and D from clade

Species B and C will have both green carapace and eyestalks

So, the correct answer is 'Species B and C both have a green carapace and eyestalks'
