Evolution is broken down into what by our professor?
-three processes and three outcomes
What are the three processes of evolution? (3)
-natural selection
-sexual selection
-chance
Define natural selection
-adaptive characteristics make the organism more likely to survive, so that characteristic becomes more common
Define sexual selection
-the opposite sex finds certain characteristics more attractive
Define chance
-random chance occurs, nature hasn’t given us the optimal bodies for example, certain characteristics occurred by chance
What are the three outcomes that occur? (3)
-adaptations (mechanisms)
-by-products
-noise
Define adaptations
-evolved characteristics that promote survival or reproduction
Define by-product. Example (2)
-adaptations (can’t call them this though) because they don’t directly contribute to survival.
Example is our ability to use the scientific method.
Define noise
-random outcomes that don’t matter
