BEAST analysis 95Â % CI divergence dates are shown within brackets and with blue bars on branch nodes. dN/dS ratios are shown in italics on the branches. Branches are colored according the clock rates, represented as substitutions per site per year. Scale bar at the bottom represents thousand years ago (Kya)Back to article page
