Biologists induce flatworms to grow heads and brains of other species

Biologists at Tufts University have succeeded in inducing one species of flatworm to grow heads and brains characteristic of another species of flatworm without altering genomic sequence. The work reveals physiological circuits as a new kind of epigenetics – information existing outside of genomic sequence – that determines large-scale anatomy. The finding that head shape is not hard-wired by the…
