The following passage is from the website as follows:
http://www.epubbud.com/read.php?g=H8AVF5J5&tocp=7 Of course, stone tools would have been only a tiny tip of a technological iceberg, dominated by wood, which has long since rotted away.
Antler, ivory and bone were just as important. String, made from plant fibres or leather, was almost certainly in use by then to catch fish and rabbits in nets or snares, and to make bags for carrying things in.
In the underlined sentence, I’m not sure about ‘as
what antler, ivory and bone were as important.’
In a way I thought ‘
what’ can be ‘stone tools’ but ‘what’ can also be ‘wood’ in another.
Can you give me what you have in your mind?
