原文：this discovery had other implications for history.
As soon as bananas appear in the archaeological record, we know we have contact between Africa and Southeast Asia. It would appear now that this contact occurred much earlier than previously thought.
Al…although…now here’s where the uncertainty comes in…we don’t really have any solid evidence of trade between the peoples of these two regions that long ago. Presumably, if people were bringing bananas to Africa, they’d also be bringing other things too: pottery, tools…all sorts of objects made for trade or daily use. But any such evidence is missing from the archaeological record.
The early appearance of bananas also suggests that agriculture began in this part of Africa earlier than scientists imagined.
