My favorite part of biology is at night. And yes -- I did fall asleep in every class. Except quantum mechanics and advanced numerical methods -- both of which the professors brutally fast pace better matched my wakeing mind.

The question of animal and vegetable is sort of Maxwell's Demon type entropy question, btw. Or one 2atHomeMom might consider. How is that? We have two gases in the same tank. One I'll label animal, the other I'll label vegetable.

Are they at equilibrium? And if at informatiomal-energy (to posit some energy-like metric that measures evolutionary advancement) equilibrium why haven't vegetables eveolved independent motion? Or why did animals?

2atHomeMom is a dope and is probably considering which screen name to take next time.

I am pretty much at equilibrium with the weeds in my yard but it was a tough two years ...

As for motion, if you don't believe plants can move, have you never seen a dandelion seed pod float in the wind headed straight for your yard?

In a nutshell, photosynthesis doesn't give you enough energy to get up and walk - you burn far more energy than the plant, and hence you have commensurately greater energy requirements.
