Differentiate between evolution and natural selection.
Evolution: The change in genetic makeup over time. | Natural Selection: The mechanism driving evolutionary change through differential survival and reproduction.
In the context of Darwin's finches, what does beak size variation illustrate?
Adaptation to different food sources on different islands.
Define evolution.
Change in the genetic makeup of a population over time.
What is natural selection?
The process where organisms with traits that enhance survival and reproduction are more likely to pass those traits on.
Define adaptation.
A beneficial variation that helps organisms survive and reproduce better in their environment.
What is evolutionary fitness?
The ability of an organism to survive and reproduce in its environment, passing on its genes to the next generation.
Define common ancestry.
The concept that divergent species share a single, related ancestor.
