We built the Tree of Life Explorer! Check it out here: https://labs.minutelabs.io/Tree-of-Life-Explorer/ And watch our video about why we made it: https://www.youtube.com/watch?v=3eE2fCLay-Q With our current understanding of evolutionary history and our strategy of cladistic naming, if we wanted to have both goldfish and sharks under a single group called "fish", then mammals must also be called fish. Thanks also to our Patreon patrons https://www.patreon.com/MinuteEarth and our YouTube members. ___________________________________________ To learn more, start your googling with these keywords: - Phylogenetic tree: a branching diagram or "tree" showing the evolutionary relationships among various biological species - Cladogram: a diagram used in cladistics to show relations among organisms - Monophyletic group (or clade): a group of organisms that consists of all the descendants of a common ancestor - Paraphyletic group: all of the descendants of a common ancestor minus one or more monophyletic groups - Similarity trap: people can name different species the same thing, only to find out they aren’t even closely related.
