A question about segmentation lengths in aquatic organisms

Post by benhj » Wed Feb 25, 2009 5:47 pm

Hi there,

Does anybody know if body-plan segmentation in any aquatic organism follows a particular trend in terms of individual segment lengths? I have run some computer simulations of undulatory organisms composed of 5 segments and I have found that over a process of simulated evolution, there is a trend for segment 2 (segment 1 = head segment; segement 5 = tail segment) to become lengthened whilst a trend for the 5th, tail segment to become shortened. I have conducted this experiment 50 times for statistical significance and always have this finding.

Best Wishes,
Ben.

Are you using the archaic definition of "segment"? If you mean metameres, your numbering system won't work; just the use of the word "segment" is problematical - it has several different definitions.
