A team of researchers affiliated with a large number of institutions in Japan has found a possible link between primitive archaea and the development of eukaryotes. In their paper published in the journal Nature, the group ...
Archaea, bacteria and eukaryotes are what biologists call the three domains of life. Of these three, archaea form an important link within the evolutionary theory. They are the direct ancestors of eukaryotes, but resemble ...
