Why Evolution is True. Brent Dalrymple Riccardo Giacconi In a very real sense, students and colleagues who were curious about science were all her children. She later formulated a theory that proposed symbiotic relationships between organisms of different phyla or kingdoms as the driving force of evolutionand explained genetic variation as occurring mainly through transfer of nuclear information between bacterial cells or viruses and eukaryotic cells.

According to her the main problem, archaea, falls under the kingdom Prokaryotae alongside bacteria in contrast to the three-domain system, which treats archaea as a higher taxon than kingdom, or the six-kingdom system, which holds that it is a separate kingdom. Quotes Sagan’s number Stewart Avenue. Joanna Fowler JoAnne Stubbe endosmibiotica However, Margulis did more than rediscover endosymbiotic theory; she restated it in the then emerging language margupis cell and molecular biology, opening the idea to scientific test.
She introduced a modified classification by which all life forms, including the newly discovered, could be integrated into the classical five kingdoms. I am not a neo-Darwinist! New York, New York: PNAS stated that the decision had nothing to do with the Williamson controversy.
