Cardueline finches can be found in many areas of the world, including North America and Asia. Hawaiian honeycreepers, which are found only in Hawaii, have been found to have DNA commonalities with this group of finches that indicate they have a common ancestor. Which mechanism might have led to the appearance of the Hawaiian honeycreeper?
A. anatomical isolation
B. temporal isolation
C. geographical isolation
D. behavioral isolation
Answer (1)
The mechanism that likely led to the appearance of the Hawaiian honeycreeper is geographical isolation, which occurs when populations are separated by physical barriers. This allows for evolved adaptations specific to their isolated environments. Other mechanisms like anatomical or behavioral isolation are not as relevant in this case. ;
