Hank re your question on how time was determined-your comments are proabably valid. The second exhibitions is not two panels but a whole exhibition, including dioramas, at the Transvaal Museum on the fossil evidence for hominid evolution at nearby fossil sites. It is fairly complex and I think I used my reading time-ie actually physically reading the whole thing in addition to a friends reading time, taking an average. Ja, a bit unscientific. But I was trying to get a figure that reflected the time needed to actually read all the panels.-probably not necessary to get quite a lot out such an exhibition-lots of littel australopithecines and Homo Habilines doing their thing.
