Assertion: Evolution is not a directed p...

Assertion: Evolution is not a directed process in sense of determinism.
Reason: Evolution is a stochastic process based on chance events in nature and chance mutation in the organisms.

Text Solution

Verified by Experts

The correct Answer is:
A

Evolution by anthropogenic action, such as excessive use of pesticides and antibiotics may lead to appearance of resistant organisms in a span of months and years, and not centuries. This shows that evolution is not a directed process, it is rather based on chance event and mutations occurring in nature and organisms respectively
