From: Genomic inference of the metabolism and evolution of the archaeal phylum Aigarchaeota
Extensive horizontal gene transfer events detected in Aigarchaeota. The maximum likelihood tree was pruned and redrawn at the phylum level according to the tree of life published by Hug et al.79. Green edges represent potential gene flows from the corresponding phylum involving ≥10 genes, and gray lines are the ones with <10 genes. Edge thickness is proportional to the number of putatively transferred genes. The sizes of red circles are proportional to the number of reference genomes collected for that phylum
