Question

Which of the following doesn't involve anthropogenic action?

• A. Development of various breeds of dogs
• B. Development of varieties of cabbage
• C. Development of pesticide resistant organisms
• D. Development of varieties of marsupials

Answer 1

Answer: (D)

Anthropogenic action is an action because of human act e.g. development of various breeds of dogs, industrial melanism (change in relative number of dark and light varieties of moth due to industrial pollution), and development of pesticide-resistant organisms.
The process of evolution of different species in a given geographical area starting from a point and literally radiating to other areas of geography (habitats) is called adaptive radiation. Darwin’s finches represent one of the best examples of this phenomenon. Another example is the Australian marsupials.
