Evolution: Haeckels fake news (Evolution)

DAVID: I am so old, I was taught in school that “ontogeny recapitulates phylogeny”. Is it possible it is taught today?

dhw: I am almost as old as you, and have certainly grown up and old with the impression that this was true. Some websites say it is true of the very early stages of the embryo, and if it is, that’s good enough for me. It has to diverge sooner rather than later, since there are such vast differences between, say, elephants, cats and humans.

DAVID: Since all embryos start as spheres of cells before differentiation they will be similar. Once differentiation has progressed, they all differ. What current websites still support this out dated idea?

Of course things differ once differentiation progresses! Here are some websites for you:
