grasping instinct

Just saw this at Jerry Coyne’s blog. Vestigial structures (click here for wiki) are fascinating. Goosebumps, hiccups, male nipples and male uterus-es all connect us to our animal ancestors. A friend of mine told me about the moro reflex recently and I decided to have a baby of my own to try it. Now all I gots to do is get my lady prego.

Thanks to Coyne’s post yesterday, I get to add a baby’s auto grasp of hands and feet(!) to my list of fun vestigial reflexes.

My question, what’s your favorite vestigial structure/reflex?
