“I was taught over and over again that the accumulation of random mutations led to evolutionary change - led to new species. I believed it until I looked for evidence.” TaughtEvidenceSpeciesAccumulationMutationGenetic Mutation Author:Lynn Margulis
“Although random mutations influenced the course of evolution, their influence was mainly by loss, alteration, and refinement... Never, however, did that one mutation make a wing, a fruit, a woody stem, or a claw appear. Mutations, in summary, tend to induce sickness, death, or deficiencies. No evidence in the vast literature of heredity changes shows unambiguous evidence that random mutation itself, even with geographical isolation of populations, leads to speciation.” ShowsCoursesLiteratureLossInfluenceEvolutionEvidenceWingsFruitPopulationIsolationSicknessStemDeficiencyRefinementClawsWoodyAlterationsHeredityMutationSummarySpeciation Author:Lynn Margulis
“The accumulation of genetic mutations were touted to be enough to change one species to another….No. It wasn’t dishonesty. I think it was wish fulfillment and social momentum.
