5-Embryology – Theory of Recapitulation Theory of Recapitulation: developing embryo go through stages resembling their ancestry evolution. The Theory: Ontogeny Recapitulates Phylogeny A discredited but famous theory 1866 Real Evidence – similarities in early stages indicates a similar ancestry, that appears briefly, but then continues onward with variation – gills / legs / tails – Hox Genes
