Extended Data Fig. 7: Histogram of delta AIC and BCI.
From: Major expansion in the human niche preceded out of Africa dispersal
A, Histogram of delta AIC between the fixed-niche versus changing-niche model in the 100 repeats. A score ≥ 2 supports the time-varying-niche model. a, Beyer et al.57 with added Heinrich events, 91 repeats have a delta AIC ≥ 2. b, PCESM58,59, 95 repeats have a delta AIC ≥ 2. B, BCI for the changing-niche model. The BCI has only been calculated on the repeats having an AIC ≥ 2, hence supporting the changing-niche model. These have been used to build the ensembles. a, Beyer et al.57 with added Heinrich events, 91 repeats with AIC ≥ 2; among them, 70% (64) have BCI ≥ 0.7. b, PCESM58,59, 95 repeats with AIC ≥ 2; among them, 55% (52) have BCI ≥ 0.7.
