Unit ____: Examples of Selection                          Name: _____________________________

Natural selection leads to changes in natural populations over time (5.2.A1).

• Outline how natural selection led to changes in the beaks of Galapagos finches.
• Outline how natural selection led to changes in the color of rock pocket mice.
• Summarize John Endler’s experiments with guppies in Trinidad which demonstrate phenotypes undergoing evolution.

Human impacts can have unintentional consequences on the evolution of a species (5.1.A1, 6.3.U9, 5.2.A2, and 5.2.NOS1).

• Outline an example of selection due to a human induced selective pressure.  
• Outline the effect of pollution on development of melanistic insects in polluted areas.
• Outline the effect of antibiotics on  development of antibiotic resistance in bacteria.

Selective breeding of domesticated animals or plants shows that artificial selection can cause evolution (5.1.U3)..

• Define selective breeding and artificial selection.
• Outline how artificial selection can lead to evolution.
• Explain an example of artificial selection in a plant.
• Explain an example of artificial selection in an animal.
