Meeting time and place

We are meeting this semester in the Bamford Room (TLS 171) Fridays from 2-3pm. Let's try to get started on time, as another group is meeting in the Bamford Room starting at 3pm on Fridays.

Theme for Spring Semester 2008

The theme this semester is Tree Thinking. David Baum (Univ. Wisconsin, Madison) is writing a book on Tree Thinking and has agreed to let us read the chapters he has written in return for some constructive criticism. Baum's book will be supplemented with some thought-provoking and heated-debate-generating papers on subjects such as these:

  • can you ever say that a clade is basal?
  • do non-uniform clade priors make sense?
  • what can and can't fossils say about node age
  • when gene trees and species trees are both right, but different
  • the signature of an adaptive radiation

Some suggested papers are listed below the schedule in the section entitled Some possibilities.

Tuesday, January 22, 2008: Basal clades

Discussion leader: Paul Lewis

Two of our Tuesday time slots this semester will be taken over by departmental seminars, so rather than waste the first time slot with an organizational meeting, let's get right into things with a consideration of the meaning of the word basal.

In this paper, Kevin de Queiroz considers how to define names for clades, and discusses tree terms such as crown group, stem lineage, etc.
