Haeckel's drawings are STILL appearing in modern science texts.

This is nice, but philosophically what does it prove?

This would seem to confirm that the embryos recapitulate evolutionary descent. Some elements are conserved while others are lost. Recapitulation is based on the concept that each organism represents the sum of its phylogenetic history. We rather think that each organism represents the sum of its evolutionary history.

Let me clarify that. Haeckel's theory was based on the concept that each species on the phylogenetic tree represented terminal evolutionary additions to the previous species. Development was thought to recapitulate all the terminal additions.

Oh, well! Sometimes the puzzle pieces don't all fit together the way we try to jam them in!
