why are most species symmetrical externally - while not internally (Feb/18/2004 )
by chance or by design?
about origin of species, evolution or intelligent design, which do you believe?

i suppose for balance and locomotion. also most species are vertebrates thus i donīt really see the point why we have our bone structure and be assymmetrical. is it intelligent design or evolution? i think both.
