My latest column for Seed is now available online. It's an abbreviated summary of how vertebrates make segments (so it's illustrated with a fly…), with special emphasis on the global and clocklike mechanism we use.

Somehow, your column is always the first thing I read when a new issue of Seed comes in the mail. Lovely article, as always.

Me too! I always read your column in SEED first also. Great article, PZ!

I have to volunteer that I received my first issue of SEED in the mail today! Actually, the August and October issues arrived together, but I'm psyched.
Looking forward to the article, PZ.

Clearly, you should have been involved in that editorial choice, PZ. At least then we would've gotten a bonus cephalopod in the process. ;-)

Wait, they make segments, and not twists in toruses? Why do you hate balloon animals so?
