aeb3 alignment

Aeb3 comprises representatives from each phylum/supergroup with no sequences from Archezoa or Euglenozoa and trimming performed after the construction of the supermatrix (resulting in 17876 positions). The removal of the fast-evolving Euglenozoa represents an attempt to further mitigate LBA artifacts. To examine the effects of missing data and specifically test how missing data influences the relationship between Archaea and Eukarya, ribosomal proteins shared by Archaea and Eukarya were deleted from some archaeal taxa
