Read the following description carefully: "When more than one adaptive radiation appeared to have occurred in an isolated geographical area (representing different habitats), it leads to the development of organisms with similar functional traits from different ancestral stocks." Identify the evolutionary phenomenon described above and select the pair of organisms that best exemplifies it.

Step-by-step solution

According to NCERT, when more than one adaptive radiation appears to have occurred in an isolated geographical area (representing different habitats), the phenomenon is termed convergent evolution. A classic example of this is the parallel evolution of Australian marsupials and placental mammals. They underwent separate adaptive radiations but evolved similar phenotypes due to similar ecological niches (e.g., the marsupial Tasmanian wolf and the Placental wolf). Darwin finches represent a single adaptive radiation.
