a Mean nucleotide variability (Ï€) for exonic and intronic regions of the functional and broad lncRNA sets in human and nearby protein coding genes and intergenic regions. Error bars represent the standard error of the mean. b Tajima's D values for exonic and intronic regions for the functional and broad lncRNA in human and nearby protein coding genes and intergenic regions. Tajima's D values were computed for observed values (green, blue, and pink) and coalescence simulations (CS, in red, yellow, and light blue). Horizontal lines inside boxes represent the medians, boxes show the interquartile range (IQR, distance between first and third quartiles), vertical lines correspond to the highest and lowest values within 1.5*IQR, and dots represent outliers
