Employability skills are generally divided into three skill sets: (a) basic academic skills, (b) critical thinking skills and (c) personal qualities. The three skill sets are typically broken down into more detailed skill sets.
In the past Archaea were classified as an unusual group of bacteria and named archaebacteria, but since the Archaea have an independent evolutionary history and manifest numerous differences in their biochemistry from other forms of life, they are now classified as a separate domain in the three-domain system.
In this tree of life, one of the basal branches evolves into a group of organisms that is part of Domain Prokarya, and is the current extant Kingdom Bacteria. Eubacteria is a synonym used by some authors for the kingdom of the bacteria. As you may recall, bacteria were first part of Kingdom Plantae (green) when there were only two kingdoms. The organisms had cell walls at least and so that was enough for them to end up in that kingdom. Once we understood that they lack a nucleus or chloroplast or mitochondrion, the bacteria needed to be moved into a new kingdom...Monera (yellow) was created for them in the 3 to 5 kingdom era. The Archaea were split out from Monera in the transition to 6 kingdoms, so Monera was renamed Bacteria (or Eubacteria).
