  • Whereas neo-Darwinists are willing to accept endosymbiosis or symbiogenesis, she will have none of theirs.

  • Neo-Darwinists including her ideas of endosymbiosis and symbiogenesis wouldn't mollify her along with theirs.

  • He rejects the widely-held notion that endosymbiosis (which led to chloroplasts and mitochondria) was the driving force in the evolution of the eukaryotic cell itself or that it was a determining factor in cellular evolution, because that approach assumes a beginning with fully evolved cells.

  • Second, there is a great deal of consensus for endosymbiosis — the idea that prokaryotes in symbiotic relationships eventually led or helped to lead to eukaryotes.

  • Margulis is lauded for endosymbiosis, and ignored when she attacks neo-Darwinism in the same way that Behe does.

  • Do we need to observe one unicellular organism consume another and subsequently observe the consumed one evolve into an organelle before crediting endosymbiosis as plausible?
