Zoology - Evolution Question with Solution | TestHub
Select the incorrect statements.
(i)The essence of the Darwinian theory of evolution is natural selection
(ii) Evolution is a directed process in the sense of determinism
(iii) The geological history of the earth is not related to the biological history of the earth
(iv) During evolution, the rate of appearance of new forms is linked to the life cycle
Options:
Answer:
Solution:
Evolution is not a directed process in the sense of determinism, for example, excess use of herbicides, pesticides, etc., has only resulted in the selection of resistant varieties in a much lesser time scale. This is also true for microbes against which we employ antibiotics or drugs against eukaryotic organisms/cells. Hence, resistant organisms/cells are appearing at a time scale of months or years and not centuries. These are examples of evolution by anthropogenic action. It is a stochastic process based on chance events in nature and chance mutation in the organisms. The geological history of earth strongly correlated with the biological history of the earth (The geologic time scale divides up the history of the earth based on life forms that have existed during specific times since the creation of the planet).
