Homology refers to the presence of a feature in two taxonomic groups due to shared common ancestry – that is, the evolutionary origin of the feature in a common ancestor of the two taxa. Homoplasy, on the other hand, refers to the opposite situation – the presence of similar features due to independent convergent or parallel evolution in two groups. Describe three features that we discussed in class that are homoplastic (i.e., they have arisen independently in at least two...
