• Complex Traits include structures or systems with multiple interacting parts

• Complex Traits include structures or systems with multiple interacting parts
• Examples: Eyes, blood clotting, flagella

• Opponents of evolution say that some traits are “irreducibly complex” and could not have evolved through small changes

• Opponents of evolution say that some traits are “irreducibly complex” and could not have evolved through small changes
• However, biologists have shown that this is not true

Evolution can produce very complex traits because:

Evolution can produce very complex traits because:
1. Natural selection allows small beneficial changes to accumulate over time

Evolution can produce very complex traits because:
1. Natural selection allows small beneficial changes to accumulate over timeExample: Eyes

Evolution can produce very complex traits because:
1. Natural selection allows small beneficial changes to accumulate over timeExample: Eyes
2. Traits may have had a different function in the past

Evolution can produce very complex traits because:
1. Natural selection allows small beneficial changes to accumulate over timeExample: Eyes
2. Traits may have had a different function in the pastExample: Lungs (for breathing) evolved from swim bladders (for floatation)
