Another update --

I have three weeks of travel coming up, starting tomorrow (South Carolina & then Brazil), but I'll try to check in here periodically. I'm continuing to work on JAM's question about body size, which has resolved itself into two sub-questions (a) how does one infer the genetic basis of traits for extinct taxa? and (b) what is the relevance of variation under domestication to possible ranges of variation for extinct or natural (i.e., not domesticated) groups?

Question for Wesley: what do you see as the canonical formulation (by Eldredge and Gould) of punctuated equilibria?  Do you see any contradictions, or simply changes of emphasis, between their 1972, 1977, and subsequent (e.g., 1993) papers?

Alb, a semi-biggish favor: would you mind sending me the complete list of textbooks you've examined, in re Haeckel's embryos? Please indicate title, authors, date of publication, level [e.g., high school, college introductory, college advanced], brief description of content on embryology as evidence for common descent, and anything else you think bears on the matter.  Thanks.  As described, that's actually a BIG favor, but I'd greatly appreciate the information.  Email: nelsonpa@alumni.uchicago.edu
