Introduction

A Phylogenetic tree or Phylogram, sometimes called the 'Tree of Life', shows the evolutionary relationships among various people that are believed to have a common ancestor. Each node with descendants represents the most recent common ancestor of the descendants, with edge lengths in our tree, corresponding to time estimates. Each node in a phylogenetic tree is called a taxonomic unit.

Although phylogenetic trees can provide evolutionary insight, they do have important limitations. Phylogenetic trees do not necessarily (and likely do not) represent actual evolutionary history. The data on which they are based is noisy and recombination and back mutations can all confound the analysis.



Analysis of Irish Type III

Presently (10 August 2012) the Irish Type III cluster has 236 haplotypes that consist of, at least, FTDNA's 67 markers. These data were taken and analyzed to produce this phylogram. Thanks are due to Alex Williamson for its preparation.
