  1. MLx, where the parameter x is the smallest ancestrality that the COG must have to be included into LUCA. The numbers of COGs in different MLx and their overlap with LUCA 1.0 [2] are also shown. Column I - x; Column II - number of COGs in LUCA-MLx; III - Number of COGs found in LUCA-MLx, but not found in LUCA 1.0; IV - Number of COGs found in both LUCA-MLx and LUCA 1.0; V - Number of COGs found in LUCA 1.0, but not found in LUCA-MLx.
