The main purpose of Oscar and Nathans journey was to find out where they migrated from and how they got to where they are now. They first went to Mahia, to find out more about Nathan and his pre-history. They next went to the Cook Islands as Nathans report said his ancestors may have migrated from there. Moving onto Oscar’s discovery they first went to Samoa where he had lived until he was 3 and later went back to visit after 18 years. After that trip they moved to the next country: Vanuatu, where they found some strong evidence that Polynesians were once there. The last trip was to Taiwan where they noticed how similar they’re language, names and traditional ways were to the Maori Culture.
Some of the discoveries I found interesting in the countries they visited were: The languages and how they were very similar, common foods of one country, pottery they made and they had very similar traditions especially between the Taiwanese and Maori for example, in Taiwan when you are greeting someone you press noses, also used in Maori culture it's called a hongi.
Some evidence supporting the theory suggesting Polynesians migrated from Asia is how some common foods in Polynesia are actually from Asia for example, bananas, taro and yams. Another piece or evidence is that the languages are similar. Simple words like the numbers from 1-10, days or the week and other basic words.
I think that the trip was successful because they found out how similar all of the cultures are in so many different ways. Like traditions, foods, myths and legend and also their pottery/art had the same patterns used in other cultures.
