Most developing cultures will use wood for their tools and cultural implements. Where wood is not commonly available, over time, people will begin using bone and stone as a means of creating tools and cultural artifacts. The oldest artifacts from past cultures and civilizations that we have are made of stone or bone for a reason... it's because the wood has long since deteriorated away in most cases. It's very rare to find wooden tools preserved in time like mummies but it does occasionally occur. What follows is some of the evidence we have of art from a time so long ago that all we can find is remains left in stone... which by itself suggests a long time of development in wood, which we have no proof of because the material (wood) has disintegrated over time BUT we do know stone tools don't erupt in any culture BEFORE wooden tools. This gives us an idea that art such as drawing images and music goes back so far back as to be timeless (probably over 100,000 years or more).
