Question
Anthropogenic actions that leads to evolution is the use of
- Herbicides
- Pesticides
- Antibiotics
- All of these
The correct answer is: All of these
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. Hence, resistant organisms/cells are appearing in a time scale of month or years and not centuries. These are the examples of evolution by anthropogenic action. This also tells us that evolution is not a directed process in the sense of determinism. It is a stochastic process based on the chance events in nature and chance mutation in that organisms
