Lake presence and Mediterranean dust records predict hominin dispersal and diversity patterns (0–3 Ma).

The migration model is one of three scenarios (see Table S2 in File S1). As species richness is temporally autocorrelated, we also ran a model of species turnover (net change in richness for each time period). All global and regional paleoclimate databases were included in the model. As above, StepAIC was used to identify best-fit models. No r2 is reported for migration as we assumed a binomial error structure. Full model results are available in File S1.
