It is
        legitimate to speak of adaptations as being 'for the
        benefit of' something, but that something is best not
        seen as the individual organism. It is a smaller unit
        which I call the active, germ-line replicator. The most
        important kind of replicator is the 'gene' or small
        genetic fragment. Replicators are not, of course,
        selected directly, but by proxy; they are judged by their
        phenotypic effects. Although for some purposes it is
        convenient to think of these phenotypic effects as being
        packaged together in discrete 'vehicles' such as
        individual organisms, this is not fundamentally
        necessary. Rather, the replicator should be thought of as
        having <EM>extended</EM> phenotypic effects, consisting
        of all its effects on the world at large, not just its
        effects on the individual body in which it happens to be
        sitting. </P></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/FDB65F73-6B62-4BF4-BD96-30AF9C8606BF/blog/" title="blog or email this clip"><img src="http://content6.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
