From: Long-term trends in evolution of indels in protein sequences
Histogram of regression coefficients calculated by approximating the dependence of domain sizes (sum of spacer lengths) on the evolutionary distance according to model #2. “Stable” domains with no statistically significant tendency to change size in evolution are shown in grey, domains increasing and decreasing in size (with P-values < 0.01) are shown in black and white correspondingly.
