demography

“Model of demographic levels and lithic technological phylogeny. The model highlights and takes account of evidence that prevailing demographic conditions will have an effect on the effective transmission of technological skills and practices. It is important to note that different demographic levels refer to relative differences in the effective population size (Ne); that is, the number of individuals passing on cultural information. Also note that demographic levels may decrease and lead to a loss of lithic elements. Dotted lines indicate instances of weak social transmission, while solid lines indicate a relatively stronger incidence of social contact and transmission” (Lycett & Norton, 2010, pg. 58)
