You Are A Fish

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. ___________________________________________ 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.
