Did you know that not all that long ago, you (yes, you!) had a tail?

I’m not talking about evolution; I’m talking your very own embryonic history. At about four and half weeks’ gestation, when you still didn’t know air and lived like a fish inside the liquid medium within your mother’s amniotic sac, you had a large, tadpolelike head and a tail and resembled “a prehistoric animal” (Nilsson 1990, 80).

So let me ask you: how does this bit of embryonic trivia change your sense of humanity, if at all?

Time for a mindful tail wag, human fish!
