The best evidence of such phenomena could be a population's genetic variation decrease.
When a population bottleneck occur it means that for some reason (i.e. environmental events) the size of a population is largely reduced. This leads to reduction of the genetic variation in that new smaller population. When a bottleneck occur, the founder effect is normally seen, which is that one population is established by a small group of a previously larger population leading once again the genetic variation, now though with a bigger population, to be very reduced.
The answer you are looking for is false
<span>Since a gene that acts as a pesticide is inserted into a corn, that corn is now safe from insects. This will happen because the corn will probably synthesise protein according to that inserted DNA sequence and that protein will serve as a repellent to the insects. However, the Red Queen's hypothesis in evolution explains that organisms must constantly adapt and evolve in order to survive. This refers to insects. If they could not eat genetically modified corn, they would extinct. So, they must adapt or evolve in order to survive. So, it is expected that insects that are resistant to this specific pesticide would develop through the time.</span>
