Re: Structuralism and evolutionary theory

Frustratingly enough, I can recall but not locate a recent article that
said that a detailed analysis of the cells after a very few divisions
(during the twin-possibility stage) showed that the division of cellular
contents were not exactly identical among the cells. The ratty part of
my lack of recall is that I cannot recall what the specific gene-related
material evaluated was. Anyone else recall this news?

In any case, this article
<http://www.umassmed.edu/pap/news/2005/10_06_05.cfm> speaks of how cell
division is not through mutual agreement of the about-to-be daughter
cells, but that one of the two resultant cells bears resultant markers
which appear to make them non-identical from this process alone. JimA
