Why don't our arms grow from the middle of our bodies? Vertebrae, limbs, ribs, tailbone ... in only two days, all these elements take their place in the embryo, in the right spot and with the precision of a Swiss watch.

The more one learns the more miraculus and mysterious life becomes!

Evidence that evolution is at least part 'right' and should be taught in science class as theory to teach scientific method. Also evidence that creationism should be taught in religious class (sunday school or equivalent) and be encountered in history class, because it still looks like some outside influence helped life on earth along in its development. No absolute proof in either direction, as usual. Fun seeing how we all start out and how the Jacquard loom of our development works.

Jacquard loom is an interesting analogy.

Noted. When will we learn that we are all a miracle of creation, and that this world is very precious? We spend too much time and effort hoping for special planets in the universe, when we already inhabit this wonderful one!
