Climate changes happen naturally on earth over time. With each recoded change, the geological record supports the concept that evolution is an ongoing process. Which biological response would support the concept that evolution is an ongoing process?

Extinctions among less genetically diverse organisms increases.
Evolution continually keeps up with environmental changes.
Adaptations to the new conditions confer reproductive fitness.
Mutations become more common among populations.
Populations migrate to previously unpopulated regions.
