If early humans (or, even proto-humans) were in existence at the times indicated by the layers of sediment, how do we explain the ignorance of the author of Genesis?
Perhaps...they were ordinary humans, uninspired by gods or spirits and lived at a time when religious superstition regulated their every move. Apart from that they were not aware of the human pedigree and therefore could not claim the paleolithic as a god story...
I get the feeling that due to its size and the (normally improving) economic situation in China, we are likely to hear more from there in the way of significant hominin finds in the future. It holds out hope of explaining early Homo erectus movement in the "out of Africa" scenario. There is the possibility that China holds a second species diffusion focus after the Great Rift Valley.
