Change in the external Environment may resulted in the changing in the population of beetles.

Genetic engineering because the genes of the plants were modified
Hydrogen would be the answer to this.
Using the gas pedal analogy, the proto-oncogene would be an accelerator since they promote cell division and
deregulate apoptosis, while tumor suppressor would
be the brakes since they constrain the progress of the cell
cycle and induce cell apoptosis. An
oncogene is, therefore, when the accelerator
is stuck in down position and the brakes are not working.
