What is a family tree?<\/p>\n
In science, family trees have been widely usedd by biologists, geneticists, ecologists, etc, to present in a more visual way the parental link between individuals. A family tree can be based on pretty much any characteristic the scientist wants. However, nowadays the main characteristic used is DNA.<\/p>\n
When we think about DNA, we think about animals, plants, bacteria, fungi and other groups pretty familiar in science. But what if other things could have DNA too? Let’s say stars could also be analyzed by their DNA and even get a family tree of their own.<\/p>\n
This discussion has started with two scientists: an astronomer and a biologist. The astronomer, \u00a0Dr. Paula Jofr\u00e9 from the University of Cambridge<\/a>, had the amazing idea to analyze stars the same way biologists do with animal species and build the Miljy Way stars family tree.<\/p>\n
