DAVID’s comment: More evidence of little use of our big brain for a very long time after its arrival.My interpretation is it took time to learn to use it.

To repeat: As with all stages of human evolution, there were long periods of stasis once the brain had expanded. Not a matter of “learning to use the new brain”. What is being learned if there has been no progress? It needs geniuses to come up with new ideas, or major changes in the environment to either necessitate new ways of thinking or provide new opportunities.
