How did senses evolve?
vision = light waves
hearing = radio waves
taste = ? molecules in matter
smell = ? molecules in the atmoshpre
feeling = Gravity
Touch came first, as single cells bumped up against things.
Taste almost simultaneously, as single cells decided what was and was not edible.
Smell is detection of molecules that are are not food or danger directly but are emitted by food or danger.
Vision, is a reaction to molecules absorbing light, as an easier way to pump ions across membranes, so storing energy formulated release.
Sound. I haven’t given that much thought. How far down the scale of evolution do we have to go before organisms couldn’t hear? Can plants hear?
