Abstract: Modern animals develop in three-dimensional space, using
complex coordinate systems to coordinate the growth of complex structures
such as internal organs and appendages.
Precambrian animals seem to have achieved a progression from one to two
dimensional body plans over a period of approximately one billion years,
with evidence of linear and then fractal-like body plans (exploring
dimensionalities intermediate between one and two), before the appearance
of regular disk-like body plans. I wish to present a hypothesis: That
the development of coordinate systems lagged behind in this progression,
and will present a mathematical model of a body plan of Dickinsonia type
which has only a single coordinate (uses only a single growth inhibiting
factor or morphogen) to produce a two dimensional body. I will close with
some comments on the relationship between the structure of
human memory and the dimensionality of the space we live in.
Prior to the colloquium, three short talks by iTHES members
will be presented as follows;
14:00-14:15 S. Wanajo (iTHES-phys)
14:15-14:30 Y. Kamiya (iTHES-cond)
14:30-14:45 W. Nishima (iTHES-bio)
14:45-15:00 break
15:00- R. Sinclair (OIST)
