Fig. 7From: New view on the organization and evolution of Palaeognathae mitogenomes poses the question on the ancestral gene rearrangement in AvesSuperposition of the mitogenome phylogeny (thin colored lines) onto the potential species tree of Palaeognathae (grey thick branches). Two mitochondrial lineages were labelled as 1 and 2. Lineages with and without duplication were indicated in different colors. The tonal transition from orange to green indicates gradual disappearing of the duplicationBack to article page
