Question

13 minutes remaining 7 of 10 questions remaining tree represents the most parsimonious explanation of relatedness among these species? refer to the image. biology: how life works © macmillan learning

Explanation:

The principle of parsimony in phylogenetics suggests that the evolutionary tree requiring the fewest number of evolutionary changes is the most likely to be correct. Analyze the shared and unique characteristics among Species A, B, C, and D. Species A, B, and C share the presence of sepals, and have similar petal - arrangement. Comparing the two phylogenies, we need to consider how many character - state changes are required to explain the distribution of traits. Without seeing all the species and traits in full detail, we look for the tree that minimizes the number of independent evolutionary events for the given traits such as number of petals, carpels etc. Usually, grouping species with more shared derived characteristics together reduces the number of evolutionary changes.

Answer:

(No specific answer is provided as the full set of species and complete analysis of the two phylogenies based on all traits is not fully presented in the question. But the approach to find the answer is described above.)
