  Phylogenetics is a widely used concept in evolutionary biology. It is the
reconstruction of evolutionary history by building trees that represent
branching patterns and sequences. These trees represent shared history, and it
is our intention for this approach to be employed in the analysis of Galactic
history. In Galactic archaeology the shared environment is the interstellar
medium in which stars form and provides the basis for tree-building as a
methodological tool.
  Using elemental abundances of solar-type stars as a proxy for DNA, we built
in Jofre et al 2017 such an evolutionary tree to study the chemical evolution
of the solar neighbourhood. In this proceeding we summarise these results and
discuss future prospects.
