Correlation analysis in the ratites tree. l represents the length of a branch, that is the time difference between a parent node and a child node, where l1=l2=t1−0,l3=l4=t2−0,l5=t3−0,l6=t4−0,l7=T−0,l8=t5t1,l9=t3t2,l10=t4t3,l11=t5t4 and l12=Tt5. The rates and branch lengths are converted into log space and then Pearson’s coefficients are computed, which range from -1 to 1. Blue indicates positive correlations and red indicates negative correlations. The darker the colour, the stronger the correlation
