Alan Cooper, Cécile Mourer Chauviré, Geoffrey Chambers, Arndt von Haeseler, Allan Wilson and Svante Pääbo investigated the evolutionary relationship among some extinct and living species of flightless birds. They concluded that kiwis are more closely related to African and Australian flightless birds than they are to the moas. What hypothesis did they propose from this conclusion?

A) That their data was incorrect and the sample from the museum was corrupted.
B) That flightless birds only occurred once in New Zealand.
C) That New Zealand was colonized twice by ancestors of flightless birds.
D) That the South American species ancestors flew to New Zealand before the flightless mutation occurred.
E) That the North American flightless bird originated from an ancestor of the New Zealand species.
