Final answer:
Option (D), Australian marsupial moles and North American placental moles are an example of convergent evolution, showing similar adaptations due to similar environmental pressures despite having distant common ancestors.
Step-by-step explanation:
An example of a pair of organisms that have undergone convergent evolution is Australian "moles" (marsupials) and North American moles (placental mammals). These animals do not share a recent common ancestor yet have developed similar body forms and behaviors because they occupy similar ecological niches, burrowing underground to hunt for food.
This phenomenon demonstrates how natural selection can produce similar adaptations in species that share a similar environment, despite being phylogenetically distant.
