Please join us for a SPECIAL TUESDAY ECOLUNCH seminar next week on 
Tuesday, April 10th at 12:15 p.m. Our speaker will be Dr. Egbert Leigh 
from the Smithsonian Tropical Research Institute in Panama. The title of 
his talk is "Neutral theory: a historical perspective". A brief abstract 
follows below.

ABSTRACT
The talk will
      1. Point out that the motive for neutral theory in population 
genetics was not anti-adaptationist, and a lot of the best neutral 
theory techniques were first developed to better understand the origin 
of adaptation. In ecology, Hubbell, at least, invented neutral theory to 
see what he could explain without invoking Darwin's principle of 
adaptive divergence
      2. Outline some crucial techniques of neutral theory
      3. Show how the current focus of ecological neutral theory on 
species-abundance distributions is about the least useful possible, 
because the same distribution could be generated by many mechanisms, and 
explore some unfinished tasks of neutral theory that must be finished to 
make it useful.
      4. Observe that the simplicity of neutral assumptions allows null 
theories of many topics, that would serve both as useful null hypotheses 
and stimuli for more realistic theory.
      5. In sum, this is an essay on how urgent it is for neutral 
theorists to "broaden the theory's bottom."
