Phylogenetic methods are widely applied in evolutionary studies in biology and are meant to reconstruct history, as long as there are heritable traits to trace evolution. Galaxies evolve and it turns out that a tracer for evolution are the chemical abundances because chemical elements are made in stars and passed from generation to generation. I will present our recent progress in using chemical abundances in low-mass long-lived stars as heritable traits, how can we use these traits to build and interpret phylogenetic trees, and how are we using trees to learn about the evolutionary history of the Milky Way. |
