A recent experiment may have placed living organisms in a state of quantum entanglement
The quantum world is a weird one. In theory and to some extent in practice its tenets demand that a particle can appear to be in two places at once—a paradoxical phenomenon known as superposition—and that two particles can become “entangled,” sharing information across arbitrarily large distances through some still-unknown mechanism. Perhaps the most famous example of quantum weirdness is Schrödinger’s cat, a thought experiment devised by Erwin Schrödinger in 1935. The Austrian physicist imagined how a cat placed in a box with a potentially lethal radioactive substance could, per the odd laws of quantum mechanics, exist in a superposition of being both dead and alive—at least until the box is opened and its contents observed. As far-out as that seems, the concept has been experimentally validated countless times on quantum scales. Scaled up to our seemingly simpler and certainly more intuitive macroscopic world, however, things change. No one has ever witnessed a star, a planet or a cat in superposition or a state of quantum entanglement. But ever since quantum theory’s initial formulation in the early 20th century, scientists have wondered where exactly the microscopic and macroscopic worlds cross over. Just how big can the quantum realm be, and could it ever be big enough for its weirdest aspects to intimately, clearly influence living things? Across the past two decades the emergent field of quantum biology has sought answers for such questions, proposing and performing experiments on living organisms that could probe the limits of quantum theory. Those experiments have already yielded tantalizing but inconclusive results. Earlier this year, for example, researchers showed the process of photosynthesis—whereby organisms make food using light—may involve some quantum effects. How birds navigate or how we smell also suggest quantum effects may take place in unusual ways within living things. But these only dip a toe into the quantum world. So far, no one has ever managed to coax an entire living organism—not even a single-celled bacterium—into displaying quantum effects such as entanglement or superposition. So a new paper from a group at the University of Oxford is now raising some eyebrows for its claims of the successful entanglement of bacteria with photons—particles of light. Led by the quantum physicist Chiara Marletto and published in October in the Journal of Physics Communications, the study is an analysis of an experiment conducted in 2016 by David Coles from the University of Sheffield and his colleagues.

One wonders what the limits could be.
I think that esp is related.. macro sensors within which smaller pieces interact.. the article mentions bacteria being entangled with photons.. easily you could imagine structures in the brain or any cell really that might facilitate something like this.. biological advantage goes to the wolf who just sense not to take the path down the hill to the right even though it smells right.
Who knows right?
