Does YOUR gut contain an entirely new form of life? Scientists say mystery ’fourth domain’ may be lurking inside us all
Scientists from Marie Curie University in Paris and the University of Montreal in Canada sampled DNA from 86 unusual gene families in the human gut.
Further analysis traced found that some sequences in these families shared 60 percent or less DNA with any known gene sequences.
This suggests, but does not conclude, that there may be a new domain of life.
Current classifications account for three groups of life: eukaryotes, bacteria, and archaea.
These mysterious #microbes may fall outside of these categories and into a fourth domain.
