Recently a number of biologists and philosophers have proposed a drastic revision of this traditional ontological categorization. They have argued that species ought be viewed as individuals rather than as classes or <a name="1"></a><A HREF="../../Notes/Notes_0/Notes_27.htm">natural kinds</A><SUP>1</SUP>. In this paper an attempt is made to show that (a) the reasons advanced in support of this new view of species are not persuasive, (b) a reasonable explication can be given of the treatment of species as classes that is consistent with current theory and practice in evolutionary biology and systematics, and (c) that once certain confusions concerning the species concept have been clarified, there are good theoretical grounds for maintaining that species are best viewed as classes or kinds.</ol></FONT><FONT COLOR = "0000FF"><HR></P><a name="ColourConventions"></a><p><b>Text Colour Conventions (see <A HREF="../../Notes/Notes_10/Notes_1025.htm">disclaimer</a>)</b></p><OL TYPE="1"><LI><FONT COLOR = "0000FF">Blue</FONT>: Text by me; &copy; Theo Todman, 2018</li><LI><FONT COLOR = "800080">Mauve</FONT>: Text by correspondent(s) or other author(s); &copy; the author(s)</li></OL> <BR><HR><BR><CENTER> <TABLE class = "Bridge" WIDTH=950> <TR><TD WIDTH="30%">&copy; Theo Todman, June 2007 - August 2018.</TD> <TD WIDTH="40%">Please address any comments on this page to <A HREF="mailto:theo@theotodman.com">theo@theotodman.com</A>.</TD> <TD WIDTH="30%">File output: <time datetime="2018-08-02T06:59" pubdate>02/08/2018 06:59:07</time> <br><A HREF="../../Notes/Notes_10/Notes_1010.htm">Website Maintenance Dashboard</A></TD></TR> <TD WIDTH="30%"><A HREF="#Top">Return to Top of this Page</A></TD> <TD WIDTH="40%"><A HREF="../../Notes/Notes_11/Notes_1140.htm">Return to Theo Todman's Philosophy Page</A></TD> <TD WIDTH="30%"><A HREF="../../index.htm">Return to Theo Todman's Home Page</A></TD> </TR></TABLE></CENTER><HR> </BODY> </HTML>
