Detailed scientific classification of modern humans, from ORGANISM via EUKARYOTES, VERTEBRATES, MAMMALS, TETRAPODS, PRIMATES and APES through to HOMO SAPIENS - depicted as a phylogenetic tree with trunk (orders and suborders of living organisms) and branches (related life forms at the coequal level of development). English and latin terms. Phylogenetic tree? !

In mathematics, Newick tree format (or Newick notation or New Hampshire tree format) is a way of representing graph-theoretical trees with edge lengths using parentheses and commas. It was adopted by James Archie, William H. E. Day, Joseph Felsenstein, Wayne Maddison, Christopher Meacham, F. James Rohlf, and David Swofford, at two meetings in 1986, the second of which was at Newick's Of course, this was just an example of the tree-building process. Phylogenetic trees are generally based on many more characters and often involve more lineages. For example, biologists reconstructing relationships between 499 lineages of seed plants began with more than 1400 molecular characters! Reconstructing trees: A step by step method The example of a family tree | Phylogenetics The example of a family tree Here is a familiar example that everyone will know about – a family tree (Figure 4). You will probably already know how to interpret patterns of relatedness on a family tree, and it turns out that the same principles apply to phylogenetic trees more generally. A phylogenetic tree is a visual representation of the relationship between different organisms, showing the path through evolutionary time from a common ancestor to different descendants.
