What are the obstacles to overcome to genetically engineer a biological radio communication system?
Imagine if you had an organ in your brain that allowed you to communicate with someone else via radio waves.
It would basically be telepathy.
What are some of the material problems that would prevent such an organ from working?
And why has radio communication not evolved in the animal kingdom, while bioluminescence, electricity and sonar have?
