According to paragraphs 6 and 7, we know that the phylogeny system — 

• groups organisms together into units called clades

• has phylogenetic or evolutionary trees and cladograms that demonstrate the same pattern

• traces the relatedness of organisms according to their evolutionary history

• all of the above are true
