Soft cover. Condizione: Very Good. 1st Edition. 372-391 pages with figures. Royal octavo (9 1/2" x 6") loose pages from Man, Volume 14, number 3. First edition. This article uses Piagetian genetic epistemology to characterize the intelligence of later Achulean hominids. In particular the Piagetin concepts of reversibility and conservation are used to assess the spatial concepts used by the hominids who manufactured the artifacts from the Isimila Prehistoric Site, Tanzania. It is concluded that these artifacts required the organisational abilities of operational intelligence and that, therefore, the hominid knappers were not significantly less intelligent than modern adults. Such a conclusion indicates that increasing intelligence has not been a significant factor in cultural evolution for at least the last 300,000 years. Concluding that later Acheulean hominids employed operational thought also suggests that such cultural realms as kinship and cosmogony may have been more complex than archaeologists have therefore imagined.
