and replicable. There are few other sciences where an isolated piece of evidence can support
or change a broad scale interpretative model without itself being readily testable.
In this framework, personality plays an important role—the conservative thinker or the
innovator, the dogmatist or the sceptic, the taxonomic splitter or the lumper. Arguably,
our safest touchstone remains the philosophical principle of Occam’s Razor, that “Plurality
should not be posited without necessity,” that the simplest of options should be preferred to
the more complex, and a parsimonious approach adopted to interpretation.
Central to the narrative of human evolution is the movements of hominins and their culture
“out of Africa,” at different temporal phases. A recent article even challenges the “out of
Africa” model itself (Dennell and Roebroeks, 2005). This paper argues that the application
of Occam’s Razor in the framework of present evidence (which can of course change in a
day) narrows both the geographical and the temporal options for explanation in the hominin
story.
