Today’s Biology Lesson. … from the Quantum World. To me this is all brand new. Nothing like this was taught when I took biology class. A. You know many birds migrate long distances each year. What is not well understood is how. But it is generally assumed they use the earth’s magnetic field – somehow. This is now explained using modern physics, particularly quantum physics. It is through the process of quantum entanglement , where two distant photons (light particles) are instantly entangled with each other no matter the distance between them. Already observed only recently in the physics lab, it is now apparently so in the biology lab for a species of Robin, and the way the photons of light entangle depends on the magnetic field. And this is how the bird chooses its flight direction. BTW, a one-eyed robin could not migrate because it couldn’t get direction information. B. You know smells, and you know not a lot of molecules are needed to stimulate a smell. Be
