Kakapo became isolated from the remaining parrot species when New Zealand broke off from Gondwana, around 82 million years ago. Around 30 million years ago, the kakapo diverged from the genus "Nestor". Earlier ornithologists felt that the kakapo might be related to the ground parrots and night parrot of Australia due to their similar coloration, but this is contradicted by recent studies; rather, the cryptic colour seems to be adaptation to terrestrial habits that evolved twice convergently. The kakapo is a large, rotund parrot; the adult can measure from in length, and weight can vary from at maturity. Males are larger
Kakapo Kākāpō 125 project aimed to sequence the genome of all living kakapo, as well as some museum specimens – the first time an entire species has had its genome sequenced. The project is a collaboration between Duke University and the New Zealand Genomics lab in Dunedin. Before the arrival of humans, the kakapo was distributed throughout both main islands of New Zealand. Although it may have inhabited Stewart Island before human arrival, it has so far not been found in the extensive fossil collections from there. Kakapo lived in a variety of habitats, including tussocklands, scrublands and coastal areas. It
