Since trees are mathematical structures and graphs, with ERIS we began consolidating an interdisciplinary collaboration between astronomers, biologists and mathematicians, in order to achieve our goal. We focused on reconstructing the evolution of the Milky Way, because this is the best laboratory but we aim at moving to extragalactic astronomy,\u00a0 by building and interpreting phylogenetic trees that are appropriate for astronomical data. To do so, we simulated the evolution of galaxies, where we know their shared history. We also used observed data, which allowed us to learn to explore the Milky Way, and ultimately help us to constrain the theory of galaxy evolution<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-47910b6 elementor-widget elementor-widget-text-editor\" data-id=\"47910b6\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>The key to chemical evolution in galaxies is the well known fact that massive stars synthesize chemical elements in their interiors, and at the end of their lives, they pollute the interstellar clouds from which new stars form. Chemically processed gas is what one generation of stars inherits from the previous one(s) and is the key observable for us to build the phylogenetic trees. Our strength is the fact that we know relatively well what elements are produced in which type of stars, and how much of each of them. The challenge is the fact that a galaxy is an open system: gas comes from outside all the time, diluting the existing one. Also, different generations of stars contribute to the pollution of the same interstellar material. Therefore, the problem is manifold and intricate, just like the biological evolution of species.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ece24c7 elementor-widget elementor-widget-text-editor\" data-id=\"ece24c7\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>The primary objective of ERIS was to propose a new field of research.
