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 or daily activity periods.
Analyze the options given: Look for the option that describes a difference in timing related to breeding or reproductive activities.
Evaluate the option about frogs: 'Two species of frogs that breed at different times of the year' directly describes temporal isolation because it involves breeding at different times.
Conclude that the correct example of temporal isolation is the one involving frogs, as it fits the definition of species being isolated due to differences in breeding times.
