Biologists induce flatworms to grow heads and brains of other species

The finding that head shape is not hard-wired by the genome but can be overridden by manipulating electrical synapses in the body suggests that differences in species could be determined in part by the activity of bioelectrical networks.

and what does this tell us? There is no new genetic information. There are no mutations. There is genetic expression as we learned it in the good old days.........

And what we use to determine species is pretty superficial.
