Before you hear the rest of the discussion, you have some time to look at questions 25 to 30.
......
Now listen and answer questions 25 to 30.
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.
Up until that time of course, academics had believed that humans first migrated to the islands in Polynesia from Asia, in the west.
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.
Yes, but Heyerdahl spent ages studying the cloud movements, ocean currents and wind patterns to find if it was actually possible.
And another argument was that there was no tradition of large ship-building in the communities lying to the east of Polynesia. But Heyerdahl knew they made lots of coastal voyages in locally built canoes.
Yes, or sailing on rafts, as was shown by the long voyage that Heyerdahl did next.
It was an incredibly risky journey to undertake — sometimes I wonder if he did that trip for private reasons, you know?
To show others that he could have spectacular adventures. What do you think, Olivia?
Well, I think it was more a matter of simpIy trying out his idea, to see if migration from the east was possible.
Yes that's probably it. And the poor guy suffered a bit at that time because the war forced him to stop his work for some years...
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?
Um, I haven't read anywhere that that was his motivation.
The most important factor seems to have been that he use only ancient techniques and local materials to build his raft.
Yes. I wonder how fast it went.
Well, it took them 97 days from South America to the Pacific Islands.
Mm. And after that, Heyerdahl went to Easter Island, didn't he?
