Which of the following refers to correct example(s) of organisms that have evolved due to changes in environment brought about by anthropogenic action? (a) Darwin's Finches of Galapagos islands. (b) Herbicide resistant weeds. (c) Drug resistant eukaryotes. (d) Man-created breeds of domesticated animals like dogs.
(a) and (c)
(b), (c) and (d)
only (d)
only (a)
evolution by anthropogenic action refers to evolutionary changes driven by human activities. The text cites the selection of herbicide-resistant weeds (b) and drug-resistant eukaryotes (c) due to the excess use of chemicals and antibiotics as prime examples of this process . Furthermore, the creation of domesticated breeds (d) like Sahiwal cows or various dog breeds through artificial selection is also a result of human intervention . In contrast, Darwin's Finches (a) evolved through adaptive radiation, a natural process of diversification in an isolated geographical area starting from a common ancestral stock, independent of human-induced environmental changes .
