Russian Orthodox cross is also called just Orthodox cross. At the same time the Orthodox churches use different crosses and any of them is called "Orthodox cross". Moreover, there are no such crosses like just "Orthodox" or "Catholic", each type of cross is a feature of local tradition. The cross has three horizontal crossbeams — the top one represents the plate which in the older Greek tradition is inscribed with a phrase based on John's Gospel "The King of Glory", but in later images it represents , and the bottom one, a footrest. In many depictions, the side to Christ's right is higher.
Horizontal gene transfer in evolution transferred. Although this may be rare, this possibility is forcing scrutiny of the validity of phylogenetic trees based on SSU rRNAs. Recent discoveries of "rampant" HGT in microorganisms, and the detection of horizontal movement of even genes for the small subunit of ribosomal RNA, have forced biologists to question the accuracy of at least the early branches in the tree, and even question the validity of trees as useful models of how early evolution occurs. <br> "Sequence comparisons suggest recent horizontal transfer of many genes among diverse species including across the boundaries of phylogenetic "domains". Thus determining the phylogenetic history
