New book expands biological classifications to account for 'alien' life

...em the highest levels are three domains ?bacteria, archaea and eukarya, the last of which includes all animals. Ward's plan places those three domains within a larger dominion, which he calls "terroan" to signify Earth origins. Another dominion he calls "ribosa" because it is based on ribonucleic acid, or RN...
