Forms of a controversial man.
A mad scientist, an amazing illustrator, the father of ecology, a charlatan. Meet Ernst Haeckel and his embryonic world.
Haeckel advanced the "recapitulation theory" which proposed a link between ontogeny (development of form) and phylogeny (evolutionary descent), summed up in the phrase "ontogeny recapitulates phylogeny". He supported the theory with embryo drawings that have since been shown to be inaccurate, and the theory is no longer generally accepted.
