Which of the following statements explains what he meant by this? speciation. evolution refers to the change in a species' features over numerous generations as a, A: Habitat destruction is currently the leading cause of current extinctions. These are not the only birds in each category. Many species of duck are temporarily flightless while moulting; they seek out protected habitat with good food supplies during this period.
