I saw wiki....But I'm suggesting it may really have originated way back.

Baskets made of?? reeds, palms...can't really think of anything else suitable except maybe animal hides....I remember seeing pouches made from hides so I'm thinking baskets more like shopping bags

I think by definition baskets are made of some type of plant fiber which is why the original statement in the article is confusing.
