Alan Cooper, Cécile Mourer Chauviré, Geoffrey Chambers, Arndt von Haeseler,
Allan Wilson, and Svante Pääbo investigated the evolutionary relationships 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 new hypothesis did they propose based on this conclusion?
1) That their data was incorrect and the sample from the museum was
corrupted.
2) That the North American flightless bird originated from an ancestor of the
New Zealand species.
3) That the South American species' ancestors flew to New Zealand before the
flightless mutation occurred.
4) That New Zealand was colonized twice by ancestors of flightless birds.
