Fig. 3

The overall evolutionary process of apolipoproteins. As the topology of the species phylogenetic tree shows, apolipoprotein family members were gained and lost in certain species during species evolution. The red and blue lines demonstrate evolutionary gain and loss events, respectively, as well as the letters ‘G’ and ‘L’. Letters and numbers above the line represent different evolutionary events that have been listed below. LAL represents lamprey apolipoprotein 1
