The story of the word

Ernst Haeckel coined it in 1866 alongside ontogeny, the development of the individual, and then claimed the one repeated the other, a slogan that dominated biology for decades before being cut down to a much smaller true remainder. φῦλον was a tribe or clan, the unit Athens organised its citizens into. Molecular data has since rewritten many phylogenies that anatomy had settled comfortably.
