Resistance to chemicals like antibiotics and pesticides exemplifies evolution, where mutations confer resistance and natural selection favors resistant organisms, changing allele frequencies.
La résistance aux produits chimiques comme les antibiotiques ou les pesticides est un exemple d'évolution, où les mutations confèrent la résistance et la sélection naturelle favorise les organismes résistants, modifiant les fréquences alléliques.
| Text | In our lifetimes, resistance to various chemicals has resulted in species' evolution. Mutation results in resistance, and natural selection selects for resistant organisms, leading to allele frequency changes and evolution. This occurs with resistance to antibiotics, pesticides, herbicides, and chemotherapy drugs. |
