<p>or genetic characteristics. In evolutionary biology, all life on Earth is theoretically part of a single phylogenetic tree, indicating <a href="page.php?w=common_ancestry">common ancestry</a>. <a href="page.php?w=Phylogenetics">Phylogenetics</a> is the study of phylogenetic trees. The main challenge is to find a phylogenetic tree representing optimal evolutionary ancestry between a set of species or taxa. <a href="page.php?w=computational_phylogenetics">Computational phylogenetics (also phylogeny inference)</a> focuses on the algorithms involved</p><p>
