Theory Briefing

• A newly identified goose species, 16 million years old, challenges the long-held theory about the origins of New Zealand's giant birds.
• The fossil suggests the evolutionary path to gigantism in New Zealand birds may be older or different than scientists previously assumed.
• New Zealand's isolated geography has long been linked to unusual bird evolution, but this find complicates that tidy explanation.
