Haeckel's Embryo Fraud - ICONS of EVOLUTION (#4)

He is known for his recapitulation theory claiming that an individual organism's biological development, or ontogeny, parallels and summarises its species' evolutionary development, or phylogeny. This theory is no longer accepted in biology, but is still very common. Haeckel invented many terms in biology like anthropogeny, ecology, phylum, phylogeny or stem cell.
