Figure 4

Morphological convergence in each type of melanosome in iridescence‐generating melanosomes. Convergence, as measured with the Wheatsheaf index, is shown for both PCAmix scores (white) and standardized traits (length, width, and aspect ratio, in grey). Error bars represent 95% confidence intervals from 1000 bootstrap replications, and P values for each measure are shown below the bar chart.
