A
A mountain range separating two populations of animals
B
A mutation causing a change in flower color
C
Behavioral differences in courtship rituals
D
Different mating seasons within a single population
Verified step by step guidance1
Understand the concept of geographic isolation: Geographic isolation occurs when physical barriers prevent two populations from interbreeding, leading to speciation over time.
Identify the options that involve physical barriers: Look for examples where a physical feature separates populations, preventing gene flow.
Evaluate the option 'A mountain range separating two populations of animals': This is a classic example of geographic isolation, as the mountain range acts as a physical barrier.
Consider the other options: A mutation causing a change in flower color, behavioral differences in courtship rituals, and different mating seasons are examples of other types of isolation but not geographic.
Conclude that the correct example of geographic isolation in speciation is the mountain range separating two populations of animals.
