The evolution of insecticide resistance in insect populations is often cited as an example of natural selection. However, a counter-argument proposes that resistance pre-exists in a few individuals and simply becomes more frequent. Which observation MOST strongly refutes this counter-argument and supports the role of natural selection?
Insecticide resistance develops more rapidly in populations with high reproductive rates.
Resistant insects often exhibit reduced fitness in the absence of the insecticide.
The specific resistance mechanism, often a change in a target enzyme, arises independently in geographically separated populations exposed to the same insecticide.
The frequency of resistant insects decreases when insecticide application is stopped.
