Plz explain this paragraph from ch7 EVOLUTION, biology ncert class 12
Dear Student,
The given paragraph tells us that due to excessive usage of chemicals by humans, the rate at which mutants are arising has rapidly increased. For example, antibiotics and drugs against pathogens has created mutated varities of microbes in a very short span (months or years; not centuries). So, mutation has a very important role to play in evolution.
Regards
