Figure 4.

A tree of the eukaryotic relationships illustrating the points of recruitment in eukaryotes in different functional systems of various domains from different biological conflict systems. With a eukaryotic tree as reference, the source and reconstructed point of transfer of various domains recruited from different conflict systems and symbiogenic events are shown. The transfers are shown as dashed arrows with the arrow head pointing to the ancestor in which the transfer is proposed to have taken place. The dashed lines are labeled either with a single gene or a set of genes enclosed in a box. The conflict systems are shown in the key at the bottom left.
