Answer to Question #24592 in Biochemistry for cathleen anderson

Question

what is the affect of pesticides and other man-made chemicals could potentially have on the process of evolution, and give examples with your response.?

Answer 1

Man-made chemicals dramatically accelerating evolutionary change in many species: plant and insect resistance to pesticides, rapid changes in invasive species.
Insects often evolve resistance within about a decade after introduction of a new pesticide, and many species are
resistant to so many pesticides that they are difficult or impossible to control (3). Similar trajectories are known for resistant weeds, which typically evolve resistance within 10 to 25 years of deployment of an herbicide.
Every year, vaccinations against influenza must be reformulated, making prediction of next year’s viral fashion one of preventative medicine’s chief challenges. The same result-a resistance, caused by mutation process and etc, will have impact on species adaptation, appearing new strong diseases, extinction of some species.
