I'd like to learn more about molecular evolution (or I think I would)...
I've been reading an anatomy / physiology textbook and that was really interesting until it got into how atoms bind into molecules... Too technical for an arts and social science student lol. Surface anatomy, organ systems, and different levels of explanation was interesting though :-)

Did you know there are 11 different organ systems?
(Cardio-vascular, Respiratory etc to give you different areas of medicine)

And I think it goes...

Atoms -> Molecules -> Organelles (not so sure what they are - strings of protein or something like that?) -> Tissue -> Organs -> Organ Systems -> Organism.

And... Anatomy deals with describing structures.
And... Physiology deals with the function of the described structures.

:-)

(I am getting a little bored waiting to start up again)

One thing I got to thinking about was that the organ systems are supposed to function to achieve / maintain homeostasis (or equilibrium) on... Maybe four things... (Temperature etc). And I got to thinking... About the (biological) meaning (function) of life... Homeostasis... Hmm...

Happy reading
