Markii Orellana uu ka soo laabtay Koonfurta Ameerika, dadku maxay ka fekerayeen warka uu la yimid? Marka la eego su'aasha hore, ku qor macnaha guud ee jawaabta. Waxay noqon kartaa 1 ilaa 20 jumladood. Macnaha guud:
Qofkii ugu horeeyay ee reer yurub ah oo ku safray webiga Amazon wuxuu ahaa Francisco de Orellana sanadkii 1542. Taariikhda aan dabiiciga aheyn ee BBC-da waxay soo bandhigaysaa cadeymo muujinaya in Orellana, halkii uu ku xadgudbi lahaa sheegashadiisa sidii hore loo moodayay, uu ku saxsanaa aragtidiisa ah in ilbaxnimo adag ay ku soo kortay Amazon intii lagu jiray 1540s. Waxaa la rumeysan yahay in ilbaxnimadii ay markii dambe burburtay cudurro ka yimid Yurub, sida cudurka shuban biyoodka. Laga soo bilaabo 1970-yadii, geoglyphs badan ayaa laga helay dhul kaymo la jaray oo taariikhdu u dhaxayso AD 0<unk>1250, oo sii wadaya sheegashada ku saabsan ilbaxnimada Pre-Columbian. Ondemar Dias ayaa loo aqoonsan yahay inuu markii ugu horreysay ogaaday geoglyphs sanadkii 1977 iyo Alceu Ranzi oo sii waday ogaanshahooda kadib markii ay ka duuleen Acre. Barnaamijka Unnatural Histories ee BBC-da ayaa soo bandhigay caddeymo muujinaya in kaymaha Amazon, halkii ay ka ahaan lahaayeen duurjoog aan waxba galabsan, ay bini'aadamku wax ka beddeleen ugu yaraan 11,000 oo sano iyadoo loo marayo dhaqano ay ka mid yihiin beerista kaymaha iyo dhulka la goostay.
