Question

multiple answer 6.15 points which of the following events would introduce a homoplasy (problematic) a phylogenetic tree analysis? a feature that was a plesiomorphy for some of the taxa a feature that resulted from evolutionary reversal a feature that resulted from evolutionary convergence a feature which was a synapomorphy for some of the taxa

Explanation:

Plesiomorphies are ancestral traits and not problematic for phylogenetic trees. Synapomorphies are shared - derived traits and help in tree - building. However, evolutionary reversal (a trait reverting to an ancestral state) and evolutionary convergence (unrelated lineages evolving similar traits independently) introduce homoplasy as they create misleading similarities that do not reflect true evolutionary relationships.

Answer:

B. A feature that resulted from Evolutionary Reversal
C. A feature that resulted from Evolutionary Convergence
