* The increasing use of antibiotics has created a strong selective pressure for bacteria to develop resistance. (This sentence shows how a human action can create pressure for evolution)
* Selective pressure from predators favored the development of camouflage in the moth population. (This sentence shows how natural pressures can drive evolution)
* Scientists believe that the selective pressure of climate change may lead to the extinction of certain species. (This sentence demonstrates how environmental changes can influence evolution)
* The selective pressure of limited resources led to the development of complex social structures in primates. (This sentence shows how resource competition can drive evolution)
* Overfishing has created a strong selective pressure on fish populations, favoring the survival of smaller, faster-growing individuals. (This sentence shows how human activity can create a pressure that leads to undesirable evolutionary changes)
