Microbiologists have announced the discovery of over 30 new species of bacteria that thrive between the teeth and gums of humans. The bacteria could not be grown in the researcher's laboratories, nor were any of them ever observed via and kind of microscopy.
If they couldn't culture them or see them, how could the researchers know they discovered a new species? If they couldn't examine the cells for the presence of a nucleus, how did they determine that the organisms were prokaryotes and not eukaryotes?
Why do some microbiologists disagree with classifying bacteria and archaea as “prokaryotes”?
