1 .Right, well, for our presentation shall I start with the early life of Thor Heyerdahl?
2 .Why don't you begin with describing the type of boy he was, especially his passion for collecting things.
1 .That's right, he had his own little museum.
2 .And I think it's unusual for children to develop their own values and not join in their parents' hobbies; I'm thinking of how Heyerdahl wouldn't go hunting with his dad, for example.
1 .Yeah, he preferred to learn about nature by listening to his mother read to him.
2 .And quite early on he knew he wanted to become an explorer when he grew up.
3 .That came from his camping trips he went on in Norway I think ...
1 .No, it was climbing that he spent his time on as a young man.
1 .Oh, right ...
2 .After university he married a classmate and together, they decided to experience living on a small island, to find out how harsh weather conditions shaped people's lifestyles.
1 .As part of their preparation before they left home, they learnt basic survival skills like building a shelter.
2 .I guess they needed that knowledge in order to live wild in a remote location with few inhabitants, cut off by the sea, which is what they were aiming to do.
1 .An important part of your talk should be the radical theory Heyerdahl formed from examining mysterious ancient carvings that he happened to find on the island.
2 .I think you should finish with that.
1 .All right, Victor, so after your part I'll talk about Thor Heyerdahl's adult life, continuing from the theory he had about Polynesian migration.
2 .Up until that time of course, academics had believed that humans first migrated to the islands in Polynesia from Asia, in the west.
1 .Yes, they thought that travel from the east was impossible, because of the huge, empty stretch of ocean that lies between the islands and the nearest inhabited land.
1 .Yes, but Heyerdahl spent ages studying the cloud movements, ocean currents and wind patterns to find if it was actually possible.
2 .And another argument was that there was no tradition of large ship building in the communities lying to the east of Polynesia.
3 .But Heyerdahl knew they made lots of coastal voyages in locally built canoes.
1 .Yes, or sailing on rafts, as was shown by the long voyage that Heyerdahl did next.
2 .It was an incredibly risky journey to undertake sometimes I wonder if he did that trip for private reasons, you know?
3 .To show others that he could have spectacular adventures.
4 .What do you think, Olivia?
1 .Well, I think it was more a matter of simply trying out his idea, to see if migration from the east was possible.
1 .Yes, that's probably it.
2 .And the poor guy suffered a bit at that time because the war forced him to stop his work for some years ...
1 .Yes.When he got started again and planned his epic voyage, do you think it was important to him that he achieve it before anyone else did?
1 .Um, I haven't read anywhere that that was his motivation.
2 .The most important factor seems to have been that he use only ancient techniques and local materials to build his raft.
2 .I wonder how fast it went.
1 .Well, it took them 97 days from South America to the Pacific Islands.
2 .And after that, Heyerdahl went to Easter Island, didn't he?
3 .We should mention the purpose of that trip.
4 .I think he sailed there in a boat made out of reeds.
1 .No, that was later on in Egypt, Olivia.
1 .Oh, yes, that's right.
1 .But what he wanted to do was talk to the local people about their old stone carvings and then make one himself to learn more about the process.
1 .I see.
2 .Well, what a great life.
3 .Even though many of his theories have been disproven, he certainly left a lasting impression on many disciplines, didn't he?
4 .To my mind, he was the first person to establish what modern academics call practical archaeology.
5 .I mean, that they try to recreate something from the past today, like he did with his raft trip.
6 .It's unfortunate that his ideas about where Polynesians originated from have been completely discredited.
2 .Right, well, I'll prepare a PowerPoint slide at the end that acknowledges our sources.
3 .I mainly used The Life and Work of Thor Heyerdahl by William Oliver.
4 .I thought the research methods he used were very sound, although I must say I found the overall tone somewhat old fashioned.
5 .I think they need to do a new, revised edition.
1 .Yeah, I agree.
2 .What about the subject matter I found it really challenging!
1 .Well, it's a complex issue .
1 .I thought the book had lots of good points.
2 .What did you think of .
