Such categories change as biologists learn more about the organisms involved and determine that existing classifications are more or less useful. They include all levels of taxons. Specializations of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVji6JwpEbGdrcN5Y29ycA" class="cyc_term">BiologicalTaxon</a> include <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjjKZwpEbGdrcN5Y29ycA" class="cyc_term">BiologicalOrder</a> and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjK65wpEbGdrcN5Y29ycA" class="cyc_term">BiologicalSpecies</a>; instances include <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi8hJwpEbGdrcN5Y29ycA" class="cyc_term">Marsupial</a> and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVicmpwpEbGdrcN5Y29ycA" class="cyc_term">Ape</a>.

The predicate <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> is used by the code which generates CycL to English paraphrases, but its applicability is not restricted to this use. prettyString The collection of all instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4r_4bScKNtQdiVw7XtX-HN0Q" class="cyc_term">ClarifyingCollectionType</a> that are used by the <font color="#ff0000">#$KRAKEN</font> application to resolve natural language ambiguities.
