So then you would presume "to know" if then that plants ARE NOT going to the same places as animals? If so, would you be kind enough to try your sense at this question, "When a seed falls does it fall to the Earth or the Sun or some other Inertial System?" For thinking this way it is impossible to tell which way the psychology went and I see not reason to think that leaves didnt some how cut them self out of this arrow called the stem invert their "tail" end in your sense and provide the animals a convertable front and back at will of the higher clade seperation level. At least the variation in amphipods is not depauperated on this thought. The problem is that bilateral symeetry was used by Kant to show God's hand in his time and I see no reason this should not be found in plants if so well as well. Instead you have descended to vulgar or common language in your linkage of filiation.
I do not think it occurs by a formula Weyl tried to use of lattice points + metric but I also do not think like Wolfram that Gould's selection on different levels can not be found. I have often wondered if Pasteur's grand asymmetry undelay biological symmetry much as an arrow could but Maxwell used the figure as well for nonorganic matter so I am matterially torn but not unthinking on the matter. Some people try to find chiralty as cause but the effect of Wolfram's program could indeed see Gould's biology trump any universality common in this to both plants and animals as well as the others.
