quote:What does spontaneous generation mean exactly?
Some will disagree, but I'll go with Gould and Huxley on that. Alleged spontaneous generation is the alleged genesis of evolution or biogenesis, i.e. bio-genesis, i.e. beginning of life spontaneously/randomly.
And neither quote you provide from Gould or Huxley indicates that this is their definition of spontaneous generation.
"Spontaneous generation" has a very specific meaning in biology and was (at least as far as the story goes) disproven by Pasteur.
