Natural Selection
Pesticide-resistant Insects
The History
We created pesticides because there was a great need for them in the farming industry. Farmers in the first place needed them do to insects and various small organisms getting into there crops and ruining them. But these organisms eventually developed a resistance and they did it pretty quickly in fact some did it in only one generation.
Pesticide Resistant Insects
After years of Farmers using these pesticides on there crops insects started to becoming immune to the pesticides they were using. They can adapt very quickly if you were to spray one insect with these chemicals the very next generation they reproduce might be resistant. Then from there those generation reproduce and so on until the entire population has this resistant gene or trait.
Four Necassary Requirements
Reproduction Reproduction is essential to the survival of the pesticide resistant insects because if they couldn't pass down the mutation that allowed them to survive they would die off. | Survival of The Fittest The other insects that were not resistant to the pesticide died because they weren't fit to survive in that environment but there offspring adapted and were able to have that resistance making them fit to survive. | Competition This was not a problem considering there was no competition between any other animals it was competition between the farmers and there pesticide. But eventually the insects won this part of Natural Selection by being able to adapt so quickly. |

Survival of The Fittest
The other insects that were not resistant to the pesticide died because they weren't fit to survive in that environment but there offspring adapted and were able to have that resistance making them fit to survive.
