Un \u00e1rbol geneal\u00f3gico puede basarse en pr\u00e1cticamente cualquier caracter\u00edstica que el cient\u00edfico desee. Sin embargo, hoy en d\u00eda la principal caracter\u00edstica utilizada es el ADN.<\/p>\n<p>Cuando pensamos en el ADN, pensamos en animales, plantas, bacterias, hongos y otros grupos bastante conocidos en la ciencia. \u00bfPero qu\u00e9 pasar\u00eda si otras cosas tambi\u00e9n pudieran tener ADN? Digamos que las estrellas tambi\u00e9n podr\u00edan ser analizadas por su ADN e incluso obtener un \u00e1rbol geneal\u00f3gico propio.<\/p>\n<p>Esta discusi\u00f3n ha comenzado con dos cient\u00edficos: un astr\u00f3nomo y un bi\u00f3logo. El astr\u00f3nomo, <a href=\"https:\/\/academic.oup.com\/mnras\/article\/2966869\/Cosmic\">\u00a0Dra. Paula Jofr\u00e9 de la Universidad de Cambridge<\/a>tuvo la asombrosa idea de analizar las estrellas del mismo modo que los bi\u00f3logos lo hacen con las especies animales y construir el \u00e1rbol geneal\u00f3gico de las estrellas de la V\u00eda L\u00e1ctea.<\/p>\n<p><iframe loading=\"lazy\" title=\"Los astr\u00f3nomos han creado un \u00e1rbol geneal\u00f3gico de las estrellas de nuestra galaxia\" width=\"800\" height=\"450\" src=\"https:\/\/www.youtube.com\/embed\/HZq1dLuhjMg?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/p>\n<p>La doctora Paula Jofr\u00e9 y su equipo eligieron 22 estrellas (incluido el Sol) y estudiaron las sustancias qu\u00edmicas que las componen, su edad y su movimiento. Una vez recopilado todo esto, descubrieron tres ramas principales en las que se pod\u00edan dividir las estrellas.<\/p>\n<p>\u00bfPero qu\u00e9 tiene que ver el ADN con todo esto?<\/p>\n<p>Las estrellas que nacieron en la misma nube de gas tienen una composici\u00f3n similar. Esta composici\u00f3n se denomina \"ADN estelar\". Dado que algunas estrellas analizadas no ten\u00edan un ADN estelar similar a las tres ramas descubiertas, es posible que algunas estrellas procedan de una galaxia diferente. Estas estrellas pueden haber sido absorbidas por la V\u00eda L\u00e1ctea y no tienen estrellas hermanas.<\/p>\n<p><a href=\"https:\/\/academic.oup.com\/mnras\/article\/2966869\/Cosmic\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter wp-image-6714 size-full\" src=\"https:\/\/blog.mindthegraph.com\/wp-content\/uploads\/2017\/03\/preview-1424544235.jpg\" alt=\"Hablemos de que las estrellas tienen un \u00e1rbol geneal\u00f3gico\" width=\"719\" height=\"464\" srcset=\"https:\/\/mindthegraph.com\/blog\/wp-content\/uploads\/2017\/03\/preview-1424544235.jpg 719w, https:\/\/mindthegraph.com\/blog\/wp-content\/uploads\/2017\/03\/preview-1424544235-300x194.jpg 300w\" sizes=\"(max-width: 719px) 100vw, 719px\" \/><\/a><\/p>\n<p>Esto es, por supuesto, s\u00f3lo una corazonada.

As\u00ed que s\u00ed, hay que seguir investigando para empezar a hacer suposiciones.<\/p>\n<p>Sin embargo, el mensaje que sacamos de esta investigaci\u00f3n es alto y claro: no tengas miedo de aprender de otros campos de estudio. Quiz\u00e1 la soluci\u00f3n a tus problemas o simplemente una mejor forma de ver las cosas puede estar justo a tu lado. O en el caso de la Dra.
