Snails Have Nodal!

Secretly I’m a bit of a science geek under my literary vestments.

I’ve just learnt that we, as in Homo sapiens, are related to the common snail. New research has just found out that snails have the same nodal as humans. We are all completely asymmetrical inside the body, unlike the outside, and it’s the nodal that decides whether, say, the heart is bigger on the left than on the right. And now it appears that the spirals on snails’ shells use the same molecule as we do.

I’ll never put salt on a snail again.
