Verified step by step guidance1
Understand the concept of temporal isolation: Temporal isolation is a type of reproductive isolation where two species breed at different times, preventing them from interbreeding.
Identify the key characteristic of temporal isolation: It involves differences in timing, such as breeding seasons, rather than physical or behavioral differences.
Examine the options provided: Look for the option that describes a difference in timing between the two species.
Analyze the option 'Two species of frogs that breed in different seasons': This option clearly indicates a difference in breeding times, which is a classic example of temporal isolation.
Conclude that 'Two species of frogs that breed in different seasons' is the correct example of temporal isolation, as it involves a temporal barrier to reproduction.
