I love it, both your Wörtespiel and the link!

This part about one lung being 3-lobed I'd never heard before:

"However, our internal organs
are largely asymmetrical. The right lung has 2 lobes whereas the left has 3, the right kidney is
usually lower and wider than the left, and the two ovaries also have significant structural
asymmetries (Davies & Coupland, 1967). Therefore, it appears as though symmetry in the
human body disappears when there is no adaptive pressure to retain it. "

...symmetry in the human body disappears when there is no adaptive pressure to retain it

Why should we be surprised? Human bilateral symmetry is truly only skin deep...one liver here, one spleen there, one stomach on this side, one pancreas on that side, one gall bladder, one...

Well, you get the picture (can't say "point" here, can I? Not in an asymmetric post!)

Something sinister is going on here...

You left something out, right?

On the other hand....for wannabee southpaws:

Can an Ultra-Sound Test Make You Left-Handed?
STOCKHOLM, Sweden (Reuters) - A Swedish study of 180,000 young men showed routine ultra-sound
examinations of the fetus can affect the brain and lead to left-handedness, Swedish radio is reporting.
The study by Uppsala University Hospital and the Karolinska Institute showed that men born in the 1970s
who had been exposed to ultra-sound tests while in the womb were more likely to become left-handed.
Most people are predisposed to become right-handed with only about six percent becoming left-handed.

If you can't see the bright side, polish the dull side.

So that explains Leonardo da Vinci's genius!!

Ummm....YES! But - butbutbut - how then do we explain the genius of the guy who invented ultrasound?

If you can't see the bright side, polish the dull side.

Whoever designed our bodies must actually be patted on the back. There's not a lot of space to waste and a lot of interlinked subsystems to cram in. Whoever it was obviously took suitcase packing lessons from my wife ...

Human bilateral symmetry is truly only skin deep

Less than that really, wofa - there's that experiment/game where you stick a mirror vertically on a picture of someone's face (along the nose line) and produce two significantly different, though perfectly symmetrical, faces. There's actually something alien-looking about perfect symmetry.

though symmetry in the human body disappears when there is no adaptive pressure to retain it
In my view, this statement puts things upside-down: If you consider evolution of organisms, the more primitive was the more symmetrical, and each breach of symmetry represented a jump in evolution (spherical -> cylindrical -> flat with differentiated underside -> front-end and back end + left and right asymmetry). It was thus "adaptive pressure" that made asymmetrical organisms "win", roughly speaking. There are still highly symmetrical competitors around, like the viruses (do not re-start a thread about this plural).

the lack of perfect symmetry is why we don't usually like our own photos-- we are used to looking at ourselves in a mirror, and we get used to that view. in a photo, we don't have that reverse symmetry, and we don't look as we would expect.

it is very interesting to take a full frontal face view, slice it down the middle, and then make two perfectly symmetrical faces out of each half.. not to hard to do with a program like photoshop.

the three images are distictly different, and both look like the whole face, but the doubled right and the doubled left often don't look at all alike.

still, there is a good deal of evidence that the concept of beauty is linked to symmetry in the face.
