And all navel oranges are effectively clonal (with the requisite amount of replication drift).  Dawkins chief subject of study was insects, so his books are filled with descriptions (and math!) of genetic similarity and divergence within different insect colonies.  Some insect species have colonies whose members have a better than (human) sibling relationship with their &quot;sisters&quot;, and in fact may even be (1&#x2F;2) clonal instances of the queen, and full clonal instances of each other.  The workers themselves are non-fecund, but their genes replicate on through the fertile queen.  We certainly don&#x27;t want to say the sterile workers are without species, <i>and</i> it may make more sense to think of the insect colony as a &quot;super-organism&quot;...if we could get past the fact that tissues and organs are distributed, but the long term success of the genetic line is concentrated in the germ-line.
