Hello All,
Because Robert Mann is busy working on the problem of *Creationism V.
Evolution* I will thru the help of a friend try to answer my above
questions.  A friend sent me a email saying he has a published study by
John B. Free ,"The Social Organization of Honeybees" from the mid 70s
(he thinks).  We can search for positive information but for the purpose
of this post i see no need.  Because i have never read the study and my
friend is quoting from memory Bee-L readers feel free to add to or
correct us.
 The study makes much of scientific trials showing bees could regenerate
glands which had ceased to be used ,effectively rejuvenating themselves
in order to ensure the survival of the colony, or even of hungry brood
given to a swarm.  We are fairly sure of the title and author.
Sincerely,
Bob & friend
