English: "Modern human cranial size over the last 300 ka using data consolidated into 100-year means. This data set follows standard practice in time series analysis by having single values at each time slice. Further, the heteroscedasticity is strongly reduced (although it is still heavily skewed). Also shown is fitted regression line with 95% confidence interval around the slope; slope = 2.78e−5 ± 8.89e−5, which is not significantly different from 0 with a p-value of 0.754. No changepoint was found for this consolidated and reduced dataset."
