In conclusion, additional information of Xiphosuran mitochondrial genomes provide more robust and reliable perspective on the evolutionary … WebTo find the most recent common ancestor of a set of taxa on a phylogenetic tree, follow each taxon’s lineage back in time (towards the base of the tree) until all the lineages meet up. That node represents their most recent common ancestor. Test your understanding of most recent common ancestors with the tree shown here.
